Latest Releases of iReal 3D Mapping Software

New functions:

(1) Color calibration module

*Support automatic detection of 24 colorchecker
*Supports multiple formats, including jpg,  png, bmp, tif, RAW (CR2, NEF, RAF, DNG, ARW)
*Support multi-threaded output
*Support CIEDE2000 color different statistics

(2) Add a new module of Focus View (below the camera list) in texture mode.

*Alt key: To turn the cursor into a cross. Click on the model to enter the focus view mode, which can display a close-up view of the area.
*W/S key: To switch photos(W/S: previous/next photo). In focus view mode, when switching photos, the view of the corresponding area can be automatically be enlarged for display.
*ESC key: To exit focus view mode.

(3) Add camera mask image input, which can effectively prevent lens stains from affecting the texture in the texture parameter settings.

*Create your own black and white images in Photoshop, with white representing stained areas (will-be-removed areas) and black representing normal areas.

Optimization:

(1) Relative orientation: Improve the computational efficiency of default algorithms

(2) Relative orientation: Automatically activate the color correction function, and perform color correction on images with significant color differences based on nearby photos

(3) Rubbing rendering: automatically smoothen the rubbing during high-resolution rubbing rendering

(4) Photo Cap: Speed up the thumbnail rendering efficiency

(5) Transformation mode: After entering the mode, automatically set the world coordinates right.

Revises:

(1) Photo Cap: Successfully oriented photos will show a green name and the number of successful photos will be counted.

(2) Absolute orientation: automatically determines whether all photos can be selected.

(3) Startup image replacement

Bug fixed:

(1) Absolute orientation: fixed the crash of clicking on global alignment when only oriented one photo.
(2) Texture refinement: fixed the crash of a white model (without textures) imported to Blender.
(3) Fixed the bug of failing in pressing the button in full screen display.
(4) Fixed the crash of continuous undo during texture seam line editing.

New Functions

(5)Absolute Orientation: Enable deleting photos that cannot align with the model to enhance matching accuracy.

(6)Fine Registration: If the Register value appears abnormal, you can halt the program anytime and revert to the previous step to review the data.

Revises

(1)The software interface layout has been restructured for a user-friendly experience, facilitating easier navigation for users.

(2)For object center perspective projection, update as follows:

• When rotating the mouse outside the model, the center of the model’s bounding box is automatically selected as the rotation center.
• When rotating the mouse inside the model, the cursor’s location becomes the rotation center.

(3)Clicking the “Close All” button will clear both data and Flow steps in the software.

(4)The Template process now includes only the “Scan Texturing” and “Photo Modeling”, with “Photo Replacement” replaced by the “Scan Texturing”.

(5)To modify a process template, navigate to “Tools → Flow → Edit Flow”. Once done, save your changes using “Tools → Flow → Save Flow”.

(6)Enable switching model directions by clicking on the XYZ axis in the software interface’s lower right corner.

(7)In Transformation mode, a grid appears along the XYZ axis, facilitating easy adjustment of the model angle.

(8)Photo Gallery: the “Show Subject Only” button has been removed. Now, when a background mask is present, thumbnails will be automatically cropped.

(9)In rendered images, minimize the black-and-white stretching in rubbing mode to connect with Photoshop for manual adjustments.

(10)The official website address has been added to Help → Homepage, and online instruction guidance can be found under Help → Help.
