Any help working with Mono on Linux would be appreciated, please give me a holler.

Yippeeeee!

I’ve finally sorted out all problems with Brahma and OpenGL, and I’m glad to announce that there will be a release of Brahma that runs on Mono (Windows + Linux, but not MacOS – I don’t have bindings for it) very soon. I’m going to be using my own method of initializing an OpenGL context on Windows and X11 using the Tao bindings for both. Stay tuned for screenshots of the samples running on Linux!

I’m really excited as I’ve never done any significant cross-platform coding, and it’s always nice to see write-once, run anywhere code!

Comments and suggestions are welcome as always.

I’ve been trying to get Brahma working with OpenGL, and although the code is complete to bring the OpenGL/GLSL provider on par to the DirectX provider (GLSL code is generated, compiles fine), I’m having problems getting results back from the GPU. I really wish OpenGL would DO something about the dreadful uncertainties across versions, vendors and drivers. I got a whiff of something called OpenCL that’s being cooked up. If delivered properly, it might be answer to a lot of woes. Anyway, I digress. There’s enough material there for a whole new post :)

I’m having problems getting a proper data-round trip between the CPU and GPU (I’m using FBO’s). I’m not sure why that is, but it works if I don’t perform any renders, but just crashes the moment I do. Since I’m at a loss as to what’s going on, I though I’d give a holler to any OpenGL experts out there who can help me figure out what’s going on.

The two unit tests of relevance in this case are

  1. DataRoundTrip
  2. IdentityTransform

Weird. Hope someone can help me figure this out soon, I’d really like to get this baby running on Linux and Mono. Thanks in advance for any help!
