iReal 2E handheld color 3D scanner, featuring with super large depth of field and scanning area, is designed for medium and large objects and human body scanning. It adopts the infrared VCSEL structured light technology to bring you safe and comfortable scanning experience of invisible light. Without marker points, a quick texture capturing and geometry acquisition can be achieved. Mixed alignment modes meet various scanning situations. With the advantages of cutting-edge algorithm functions, easy-to-use software, ergonomic design, portable and durable, iReal 2E creates an efficient, accurate and rich texture 3D color measurement solution.
The difference between iReal 2E and iReal 2S is that the latter has better scanning details and stronger material adaptability due to blue scanning mode.
iReal 2E 3D scanner, a device based on the principle of structured light, is composed of 3 VCSEL infrared emitters and a CCD camera. The fixed and coded speckle projected from VCSEL onto a measured item, and CCD camera calculates the spatial position (X, Y, Z coordinates) according to the speckle changes. The point cloud data of the surface contour of the object is obtained for 3D reconstruction.
When violating the principle, we can’t capture data that will result in splicing failure.
Please connect the computer to the power supply and set the power mode into high performance when scanning.
Please close firewall and third-party protection software that might cause high-latency scanning.

Change from Real Viewer to iReal 3D.
UI of this version software has all been upgraded for better and more convenient use. The corresponding interaction logic is also different from Real Viewer, which will be introduced in detail below.
Improve real-time scanning quality and add a new intuitive function – chromatogram display.
Add real-time project file saving:
It supports us to save project file at any time after pausing the scanning.
Improve the efficiency of on-site operations through using multiple computers to process project files.
Hair scanning enhancement mode:
Turn on this option to make a clear scanning of hair.
Its principle is to increase scanner’s recognition of thin and black hair. In actual operation, we can use this function to scan not only hair, but also for all hair-like objects.
However, hair enhancement mode is also a double-edged sword. Enhancing the black effect means that it might overexposure to cause low quality data and generate some noise when scanning a white object. Therefore, we should pay attention to turn off the option when scanning some matte objects.
Invisible light scanning mode:
Perform 3D scanning without any visible light to bring you a safe and comfortable scanning experience especially for human body scanning.
We can select certain resolution under the drop-down menu on the right of “finish” icon after scanning.
Different resolutions mean different scanning details.
The closer the scanning distance is and the longer the scanning time is, the better the details.
We can scan it with closer distance and longer time as soon as possible to reach a certain part with high details. After this operation, select 0.2mm resolution before click “finish” icon.
However, how do we know is it ok? Please refer to chromatogram display.
There are default scanning distance ranges under different scanning modes for better work. We can edit it under real-time scanning parameters according to your custom.
iReal 3D V3.0 supports multi-scene switch among project interface, point cloud, mesh files, and color mapping because it saves these scanning files in memory. The function helps us get the desired data state quickly while adding some memory consumption.
We can even return to scanning interface after mesh wrapping. It is worth noting that the previous files will be covered after point cloud process and mesh process, which refers to that there in only one kind of data in every interface.
Are you worried about scanning crash or emergencies like power outage? We add this new function to recover project files and keep scanning.
Mark points scanning splicing mode:
Do we need to align the coordinates and then export it before saving the files?
We offer Coordinates straightening we add can be found in tools and the icon is like this . Click the icon to rotate the 3D model to face us and export it. You will find the 3D model is straight in other third-party software.
Note: The 3D model in iReal 3D scanning software is still in statu quo because the model data should be matched with mapping, coordinates. So, it can’t be changed at ease.
It is on the top bar of tool interface. Scanning data has changed to red and green after starting the function, and red means low quality data and green is high quality data.
Real-time chromatogram display allows users to check the data quality clearly and scan again with closer distance and more times for those low-quality data to ensure the data is with high details and integrated.
See chromatogram display for more details.
When there is abnormal for colorful texture scanning, we can find calibrate interface and click white balance icon to calibrate it. Take out the calibration board and put it on the table, then focus the scanner on the grey card on the left. Press the device button and keep it for 5 seconds to finish white balance calibration.
When having a wrong operation, we can click this to reset white balance and restart it.
See calibrate process for more operation.
There is an arrow near the icon of mesh wrapping after click “finish” , which means other options can be selected. If you ignore it, it will run on the default parameters. At the same time, we can return to re-select when forgetting some operation.
The default parameters are configured through the most commonly used schemes based on a deliberate consideration.
iReal series tutorial
This is the main and precise working device, please don’t drop it.
Please handle with care because it’s made by glass.
When the internal structure of the scanner has errors due to external factors, the board is helpful for calibration.
Marker points are stuck on the surface of those items with less features or the surrounding to help scanning.
This product uses 90W input power.
It’s for data transmission.
The outer packing box of this set is for daily store and carry.
You need to plug in the dongle every time you use the device to scan for the security.
E-AR Display Module (Optional)
It’s more convenient that the scanning interface can be displayed on the glasses in real time.
It’s necessary to close third-party protection software before the software installation and the scanning process, which might result in latency.
Software is suggested to install in the disk with large storage space.
Graphics card setting:
Right-click on the computer desk — Open NVIDIA control panel — Click “Manage 3D Settings” — Click “Program Settings” — Manage selection of the graphics processor — Choose high-performance NVIDIA processor and — Add — iReal 3D.exe — Apply.
Please turn the arrow mark on the power cord over to the top, align the four thimbles with the power port socket, and then gently plug it in.
It needs to import the configuration files located in U disk for the first use.
Importing the configuration files is the key to have a normal use of the software and hardware after starting iReal 3D V3.0.
The configuration file is the third most important thing besides the scanner and calibration board, please keep and backup it properly.
When a prompt appears in the lower left corner of the software, the license status of the device has expired. Please contact your salesperson to obtain the latest license file.
Follow these steps to update it:
iReal 3Dand open the file location.
iRealSETcan be found.
The device should be calibrated before 3D scanning for the first use in order to have a calibration on camera parameters. It needs to be calibrated again in the following situations:
which cannot be upside down, and connect the device. Click calibration icon after it shows connected status.
Don’t turn over the calibration board when operating. There isn’t any feedback in the process of calibration when the board is inverted.
The three orange circles represent three cameras of the device. Blue means the camera can capture the markers on the board while orange vice versa. Please adjust the angles to change the color of orange into blue.
There are 5 steps: right above, upper right (inclined), upper left (inclined), upper rear, upper front.
It’s not necessary to calibrate the white balance for the first time. The purpose is to calibrate the color standard according to the light environment at that time. Calibration is required in the following situations:
Click the WB icon to reset if there are any mistakes.
Click the WB icon to quickly return to factory settings when coming back indoors.
Click the icon of point cloud to enter into the surface. The top tool bar can help you delete the isolated point and disconnected components. Select the way of filling holes to generate mesh data through the arrow that is near the icon of mesh .
There are three ways of filling holes:
Not Close Holes: It means fast saving and not closing any holes, and this kind of file is suitable to import third-party software to process.
Close Small Holes: In human body scanning mode, closing small holes will extend the edge to trim holes while it will trim most of holes in object scanning mode.
Fully Close Holes: All holes will be filled. The filling effect will be not good if trimming the holes that are obviously not able to be enclosed.
There are tools such as mesh simplify and mesh refine after clicking the icon of mesh to enter into mesh interface. Choose whether to smooth the texture and generate it by the arrow near the icon of texture .
Smooth texture will optimize the color and decrease the details.
Click to enter into texture interface. The tools include the adjustment of hue, saturation and ambient.
The whole project is divided by 4 modules based on scanning process and each module represents a kind of data and an interface.
This is tools interface which is relatively isolated with scanning process.
The action of saving the file can be carried out at any time that is located in the upper left corner of the interface.
Therefore, what kind of data we want to save depends on what module we have finished and what type of file we want to save.

Open a single file in the folder such as ASC, STL, etc.
Open project file
Open the index file (.epj/.apj./.spj) under the project file.
It includes three types: scanning project file (.epj), point cloud project file (.apj) and mesh project file (.spj).
Save and open
A folder with the specified name will be saved in the specified location.
The folder is different from ordinary neutral files and includes multiple files.
Click “Open Project File” when opening and find the right *pj file.
The project file supports to be saved at any time during the scanning process.
Its attractive feature is that you can continue to scan after opening it next time and supports offline process.
Point cloud project file
It will be saved in the specified location with specified name.
The folder includes
.asc file and
It’s the index file of oping project file.
ASC file can be copied and warped to generate as
STL file in third-party software. This
STL project file can be mapped in
iReal 3D, but the premise is that the coordinates have not been modified in the wrap process. 2
ASC project files can be registered in
iReal 3D including the texture information.
It saves the texture information that can only be read in
iReal 3D. The software will try to map the texture information to the
STL file when opening them though the
STL files aren’t original files.
The greatest function of project files is that they can make data registration between two files.
Mesh project file
It’s same as point cloud project file, which includes
spj file that has the same functions with
TextureImage and a
STL file can be used as single-color model for
3D printing, data archives and supporting other third-party software.
STL file can also be imported to restoration software and sculpture software to make optimization. The optimized file needs to be saved under the original location and then mapped in
Mesh project file can support make texture mapping after optimizing the model.
Although iReal 3D scanner works fast, you cannot scan across it. The right way is scanning the objects from all angles to ensure that the data gets complete and check the chromatographic display at any time.
Otherwise, there may be more data noise and have orange peel phenomenon.
Move back to previously scanned area and stay for 2-5s.
The scanned area should have as many features as possible, and the space span should not be too large.
If it has not been retrieved for a long time, you can press the pause button on the hardware first and then aim at the scanned area again to try to recovery it.
Keep the scanned area with rich features to avoid mis-splicing.
It needs to form a closed loop of scanning path and keep smooth and slow scanning.
Try to scan from the middle to the periphery when scanning medium or large items such as carvings and human body.
Multi-angle scanning will help you obtain more details and higher accuracy.
Hair scanning is more difficult because of the fewer features, so we need to align with the help of body parts.
Try to bundle or tie your hair up for the better scanning.
It’s necessary to tell the scanned person to keep as still as possible and look straight ahead before scanning.
Remove the difficult-to-scan objects such as reflective accessories, glasses and watches.
It’s better to keep eyes opened to reduce mending work if 3D data is used for 3D printing or portrait sculpturing.
Keep a stable and fast scanning for body because of avoidable and slight movement.
Have a first scan for those body parts are difficult to keep still and try the best to finish the data capture in one scan.
Extreme poses should be supported by auxiliary tools, such as T pose and A pose.
Please scan the arms at one time because of easy shaking in T pose and A pose.
Chest – Face – Hair – Chin – Chest – Right leg – Belly – Left leg – Right arm and hand – Back – Right leg – Left leg – Butt – Hair – Left arm and hand.
We can make artificial texture to help data splicing when there are not any features.

Black Material/Hair Scanning Enhancement Mode in tool bar.
Hairs are difficult to scan as they reflect light in random directions, you can try to apply dry shampoo or mat color spray on the hair to turn them mat.
Or do the post processing with a mesh editor. You can find some library or draw hair using 3DMax, Maya, Blender, Z brush. These kinds of software require advanced skills.
increase the physical ups and downs.
Light source and fill light can be edited at any time in the process of scanning, and we can also change the point distance after scanning which will affects the models. See the function of chromatogram display for more details.
All three default scanning modes have complex algorithmic logic, so customization is not supported.
Human body scanning mode
The default parameters: color scanning, with fill light, splicing by features, 0.7mm point distance, 280-600 mm scanning distance.
Object scanning mode
The default parameters: color scanning, with fill light, splicing by features, 0.7mm point distance, 280-600 mm scanning distance.
LED off model
The default parameters: colorless scanning, without fill light, splicing by features, 0.7mm point distance, 280-600 mm scanning distance.
Each blue circle under the icon can be clicked to hide or display the mode icon in main interface.
In practice, custom mode is probably the mode we use frequently, so how to add a new custom mode?
Why need to splice data? It’s not enough to generate point cloud and wrap by imaging in one moment when we scan large objects, which is like putting blocks together. The only way is to capture the whole data of the scanned item while there are several factors such as splicing failure preventing us from scanning smoothly.
If there are rich, irregular and non-repeatable spliceable features in the common area of the two scanned frames Below three feature splicing modes can complete the splicing.
And the point cloud of two frames in common areas may be mis-spliced/un-spliced when there are too few point cloud data/spliceable features.
We can gradually complete the scan by precisely matching the data based on the fact that each frame of the scan is different for those scanned objects with obvious geometric features.
Figure 1: Common area with rich features helps have a smooth splicing.
Figure 2: Common area with repeatable features may fail to splicing.
Figure 3: There is a few features that will cause an unsuccessful splicing.
Figure 4: Little point cloud data is a factor of failing to scan.
It’s similar to feature splicing and depends on rich variation of patterns.
Reflective marker points are identifiers that the scanner can recognize, which help the device make judgments of the scanned position.
However, a marker point is only identified as a coordinate point in space, and there are many more coordinate points like this that do not constitute uniqueness. Therefore, three or four nearby marker points need to be formed into a geometric recognition with high uniqueness to perform a stable and accurate splicing.
The distance between each two markers is 30mm to 80mm, and it should be determined according to the actual situation. If the curvature of the surface is small, the distance between the markers can be farther, the maximum distance is 80mm. If the curvature of the surface changes greatly, the distance between the markers can be
smaller, the minimum distance is 30mm.
When pasting the marker points, try not to paste the obvious features to avoid the loss of key feature data; the more irregular the pattern composed of marker points, the less likely to be misspelled; the pattern composed of three marker points should not become isosceles/ equilateral triangles; try to paste the marker points on different levels, the splicing accuracy will be higher; when scanning the marker points, you need to identify the marker points through different inclination angles (right above, front / back / left / right / slant 45°) to ensure the identification accuracy of the marker points.
The mechanism of hybrid mode adopts splicing of marker points, features and texture with different weights.
Marker point splicing > Features splicing > Texture splicing
Objects that are partially flat, patterned, and feature-rich are suitable for hybrid splicing.
Sticking 4 or more reflective markers in a single frame on a flat part before scanning, smooth data splicing can be carried out. The larger the flat area is, the more markers are stitched.

Invisible Scanning Mode
Prepare two ASC project files that should have large common area.
If the model is too large, you can use the surface reduction tool after wrapping.
How to replace STL file and cover color in RealViewer 2.0 and above version?
- One low-quality 3D model including (Hereinafter referred to as low poly.)○ 3D data scanned by iReal device.○ ASC point cloud project file.○ 3D data aligned by 2 point cloud project files.
- One high-quality 3D model including (Hereinafter referred to as high poly.)○ 3D data scanned by laser scanner.○ Sculpturing data in ZBrush.○ Optimized data of a low poly.
- Please note that a dongle is required when opening realviewer 2.6.5 or above version.
- Wrap the low poly in iReal 3D and save it as STL project file, then a folder is formed including RTImageMessage.asc, text.image and XXX.stl.
- Align the coordinates of the high poly to that of low poly in Geomagic studio, and wrap in Gom Inspect. Please keep the high poly (movement) moving to the low poly (fixed) because the latter one is project file and its coordinates should be accordant with col or information.
- Export the high poly and move it to the folder of the low poly after the coordinates are aligned. Please pay attention to the naming to distinguish the two models.
- Open the high-accuracy model in iReal 3D which will automatically perform mesh optimization and mapping.
- Make appropriate adjustments and export it to OBJ format that can be covered colors.
Matte and light-colored objects can be easy to scan the 3D data.
Items with rich colors have better mapping.
The color difference of monochrome items is more obvious.
It needs to spray powder on black, transparent, highly reflective objects to finish the scanning.
The objects with the size of 30cm is better for scanning.
Scanning spray can be applied on any surface (black reflecting, transparent, etc.) to improve the point cloud data quality.
Such as glass and transparent plastic.
It cannot scan glass since the scanner light will penetrate the glass which makes the camera unable to accurately capture the location of the reflected light. In the case of translucent items, the camera receives insufficient signal from the reflected light to complete the data acquisition. In addition, impurities in translucent objects can affect the reflected light, and the messy reflected light causes the data not to be acquired correctly.
For example, jade, ceramic, etc.
The scanner light hits the surface of the object and penetrates inside the object, resulting in the location of the light captured by the camera not being the surface contour of the object, thus affecting the accuracy of the scanned data.
Like mirrors, metal processing and highly reflective surface.
The camera is supposed to capture the diffuse reflected light after the scanner light hits the surface of the object, while highly reflective materials such as mirrors produce specular reflection of light because of smooth surface, so that the scanner’s two cameras cannot capture the reflected light at the same time.
The light information reflected to the camera becomes less because black items absorb light, which will reduce the scanning speed or cause difficult capture of data.
The above parameters can be changed at any time.
Value range: 0-100
Default value: 5
It only effects on splicing mode.
The programmer valued all objects for features to distinguish between strong and weak features. If the value is adjusted to 30, only features that reach the value of 30 will be involved in the splicing while weaker features below 30 will be ignored. Weaker features are easily misidentified to lead to mis-splicing.
Increase this value to avoid data mis-splicing. However, it also improves the splicing difficulty. It can be used in feature or mixed splicing.
Feature value of common objects can be observed in the bottom bar when scanning.
See scanning distance for details.
Value range: 0-1
Default value: 0.85
The value of 1 means the flatness accounts 100%.
The higher the value, the less likely it is to be mis-spliced.
Value range: -2 -2
Default value: 0.3
When scanning objects that are difficult to scan with black surface, decreasing this value will increase the number of points and accordingly the noise. On the contrary, increasing the value to reduce noise. Although it’s with high-quality data, there are fewer data to be captured. Only when the scanned object is the best material to scan.
Stray colors are involved in the calculation in the camera shot in dark environment during 3D reconstruction, which results in some unwanted deviation values that appear over the surface of the item. Sometimes it is very far away, sometimes it is very close. When it is very close, wrapping point cloud also participates in the calculation to result in orange peel on the surface of the data, and thus the data quality is not high.
The scanner is based on camera imaging, so there is a depth of field issue. iReal 2E has a scanning depth of field of 280mm-1000mm, 720mm in total.
The scanning distance affects the details and splicing. The purpose of this parameter is set up to keep the depth of field within a reasonable range and ensure better detail richness.
The closer the distance, the better the detail. Chromatic display tends to be green, the more difficult the splicing.
The farther away, the worse the detail. Chromatographic display tends to be red, the easier the splicing.
Generally, we will pre-set the best scanning distance in each default mode, but it may not meet everyone’s scanning habits. It can be edited in real-time scanning parameters .
Chromatogram display is located on the top tools in the scanning interface.
Short-range and long-time scanning helps capture rich details according to real-time resolution and high-resolution scanning on parts.
Observe scanning distance on the right bar to check our scanning distance, then how to know the long-time?
It can select a certain resolution after generating point cloud, see scanning process for details.
Scanning data quality will be presented in different colors after clicking the icon of chromatogram display.
Green refers to high quality data and red is on the contrary.
Suggestion: Don’ t open smart color map when using human body scan mode. This mode is special because human body is easy to move such as breathing that might cause scan errors in the real-time scanning.
The range of chromatogram display various with the change of resolution. The area of green will be decreased under 0.2 resolution while be increased under 1.0 resolution. The reason is that the higher resolution models require more details.
It allows you to have a real-time and clear check of parts with poor data. You can optimize it without professional judgement by performing a repeated scanning with closer distance to turn into green. A perfect and high-quality 3D model is obtained easily.
The richness of the details can be interpreted as the resolution on the 2D picture. The higher the resolution of the same scene, the richer the details.
The deviation value between the scanned model and the actual object is regarded as scanning accuracy.
Regarding the frame rate, the default of 1Ofps will suit your needs.
If you want smoother stitching and your computer has z6G video memory,you can increase the frame rate to 15 fps.
The faster the scan speed, the more data you getin asingle frame, the better the geometry stitching.
