3D engines under active development?

[bbmario]

Are there any DC-specific 3D engines under active development, using the KGL wrappers?

Unfortunately KGL was in a quite sorry state before but it's picking upsteam recently. So I think most engines used PVR directly before.. If you're using a third party engine like CubicVR you should not need to care about whether they use KGL or PVR internally though. What are you trying to do?

Using PVR directly means writing raw PowerVR ASM?

My current objective is just a small 3D game. Something like marble blast or a platformer.

There is no such thing as PowerVR ASM. The PVR isn't a programmable GPU -- it is fixed-function.

As bogglez said, it shouldn't matter whether the engine uses the PVR directly or uses KGL, as it should expose the functionality you need without ever having to touch either of those layers directly.

There is a C API http://gamedev.allusion.net/docs/kos-2.0.0/pvr_8h.html
It is a Dreamcast-specific graphics API. You can use the KGL implementation for simple stuff too, the performance has improved a lot.
But the implementation is not complete.. if you encounter errors you can report them here:
