Yes, the new ogles2.library is intended as Warp3D Nova wrapper for all the OpenGL ES 2.0 commands so OpenGL ES 2.0 ports can be more easily ported across.
As you can imagine the Warp3D Nova project is mammoth undertaking, and it has been a year so far in the making. The pre-release version (1.15) was made available to the public/developers back in May to start the ball rolling with third-party developments. The idea was to incremently add more advanced features through free updates such as Stencil buffering and Mip Mapping. Stencil buffering has now been recently added and Mip mapping is almost there (a week or less) so the bulk of the work is now done.
Going forward over the next few months, there are a few last things to do such as enhancing the Shader compiler and refine it further, render-to-texture/bitmap as texture and finally smart register allocation. The ongoing development process will not prevent third party developers use it for their projects, in fact there are some in process now (I will not steal their thunder by pre-announcing them).
I'm sorry if my comments might sound a bit critical but I've been burned more than once over the years when it comes to OS4 and OS4 hardware support.
I can understand the scepticism, but that is one reason we wanted to get the pre-release out there and build upon that foundation with regular free updates rather than hide it away for months (years) without being practically used by developers and users. We wanted to show that Shaders on AmigaOS are real and can be used now.
