How to use Relative Orientation in Metashape?
3. When using Relative Orientation, you can check Metashape for calculations.
What should I do if my computer prompts a virus after downloading software?
When some customers download iReal 3D scanning software, iReal 3D intelligent mapping assistant or other related files using the channels provided by iReal 3D’s official website, they may encounter a browser pop-up window “virus exists” after the download is completed.
In this case, you need to complete the following operations in the computer settings:
Open the computer system settings and enter the “Security Center – Virus and Threat Protection” interface. Turn off “Real-time protection”, “Cloud-provided protection” and “Automatic sample submission“.
Once you have done the above, you can download the software normally!
(The files downloaded from the iReal 3D website are virus-free and pose no threat to your computer’s security, so please feel free to download them!)
What is the difference in mapping results among the common color 3D mapping methods?
3D Laser Scanning + DSLR Photography + iReal 3D Mapping Software vs DSLR Photography + Photo Modeling
Conclusion: The difference in mapping results is not significant.
3D Laser Scanning (Resolution 0.2 mm) vs. DSLR Photography + Photo Modeling (High-poly)
The 3D data obtained by 3D laser scanning has higher precision (up to 0.02 mm) and can restore the details of the scanned object to the largest extent, and the mapping effect is much better.
3D Laser Scanning + DSLR Photo + iReal 3D Mapping Software vs iReal 2E 3D Color Scanning
The mapping result obtained via DSLR is way better than via color 3D scanning, no matter from its color definition or color restoration, especially when 3D scanning medium or large-sized objects.
3D Laser Scanning vs. iReal 2E 3D Scanning (Both Resolutions Are 0.2 mm)
Conclusion: The 3D data obtained by 3D laser scanning restored more details of the object
(especially in the face of reflective parts, black parts, small and medium-sized parts, slender parts, etc., the scanning results will be better), and the mapping effect will be better.
Is the process of Photoshop a must?
This step in Photoshop can be selectively skipped according to the requirements for texture quality.
When do you need to extract the mainbody and when you don’t?
The purpose of extracting the subject is to prevent the background from interfering with the orientation, and the decision of whether to extract the subject is based on whether the relative position of the object and the background changes. If the object does not move and the person moves, there is no need to extract the subject; if the object moves (such as taking a picture on a turntable) and the person does not move, the subject needs to be extracted.
What should I do if the software crashes?
If you encounter a software crash, you can find proj.flow under the project directory and drag it directly into the software. It automatically saves the data in the process but does not save the operation.
Is the step of seam line editing a must?
If there is nothing wrong with the seam line, you don’t need to edit the seam line especially.
What is center point zeroing? What could make the model position change?
After zeroing the center point of the model, you can rotate it how you want. Center point zeroing is to return the center of the model to the center of coordinates. After the center point is zeroed, only the translation/rotation function will change the actual position of the model.
What is the function of model baking?
When the model is baked, it is two-way baking. The mid-model bakes the texture map for the high model, and the high poly gives the normal map of the mid model.
How to make sure the texture is accurately aligned with the model?
You can check whether the camera position is around the model during fine registration, or you can return to the absolute orientation to check the result after fine registration.
