I created a library to display polygons in 3D. It is also possible to use it to create 3D XUI views.
This library can be used to create 3D models from code or load them from obj files.
To create a 2D drawing app, to create games, animations, introductions, and 3D effects
You can find a detailed description of the methods and algorithms used in this thread.
After a long and troubled reflection that has lasted for months now, I decided to release the complete library in B4XLib format. This will improve performance.
At the same time I do not authorize to open or decompile in order to obtain the original source. I do not authorize any changes to the source.
You can use the library in your applications, including commercial ones, by inserting the author's acknowledgment of this library.
The examples must be updated to select the complete version of the library (no longer SD_XUIView3D_DEMO but SD_XUIView3D)
If you want you can make a donation for this library, I would be grateful.
