B4A Library 3D Bodies - Four libraries

Reuse of something I did in B4ppc days and got a round tuit now for B4a.
There are three libraries, doing similar thing with variations:
1. A 3D cube, with or without dice numbers on, can roll by touch or by command or provide a throw result by click.
2. A 3D library for any body, provided that you know how to define its verteces and polygons. There are examples of several bodies which may help, see photos.
3. A 3D library for any body (like 2 above), using Open_GL 1 library (thanks to Agraham). Note that I have very limited knowledge on the use of Open_GL and this implementation is very basic, however the user of this 3D library does not need any knowhow of Open_gl at all.

In all libraries you can create a view which is a base panel and the body on it. The panel may be transparent or with a bitmap.

A demo application is attached, including the bodies in the photos and a surprise.
The documentation is inherent and simple.
Important: The demo with the BodyGL library has some code with a timer - the specific item will fail when running in rapid debugger or even in legacy, but runs well in release mode (probably due to heavy load of Open_GL).

The three libraries use a coordinate system in which X is to the right, Y is up and Z is into the device. Flattened to 2D, z is diagonal from bottom-left to top-right.
The units of this system are much larger than the pixels, few units cover the display (depends on the z coordinate and the ViewAngle.

Edit: Cube3D updated to ver 1.01 , now its possible to define it as custom view.
see post 3 for details.

Edit: Ver 1.02 - CubeGL added , doing what Cube3D does but using openGL.
Cube3D and CubeGL both are also CustomView in the designer. See post #5 for details.
Edit: Frame line option added to BodyGL.
Edit: Body3D version is updated to 1.1, removing a limit of the number of points in a body and adding ViewAngle method. It is updated in 3D.zip file.
Edit: all libraries updayed to ver 1.2, inclusion of LineWidth method.

Note: The examples use openGL library , not updated to openGL2 !
