Hi!

We are using Optix from .NET ourselves and would be very interested in this project. I have been using optix in managed code using C++/CLI, and have some ideas for such a .NET wrapper lib. To list a few:
* An interface similar to that of optixpp
* Proper IDisposable implementation instead of reference counting, including automatic GC cleanup. (Just don't try to destroy optix objects after their context has been destroyed, we've hit that one a few times...)
* Using interfaces for all classes to allow dependency injection and faking in unit tests.

Do you have a link to the project repository?

Tobias

I was going to post it here once it was a little farther along :) You can also find it here: http://optixdotnet.codeplex.com/

Thanks for the suggestions! The interface at the moment is similar to optixpp with some added convenience functions/classes.

The math library is incomplete and OBJ loading is not complete (should be done by the weekend). And unit tests still need to be implemented.

I think a neat addition would be to do something similar to CUDAfy and allow writing optix programs in-line in C#.

Edit:
Latest now has PBO backbuffer support, better OBJ mtrl/group handling, and PathTracer sample.

Released Beta 2.0 for Optix.NET:
-New D3D11 and Optix interop Instant Radiosity sample
-New Visual Basic sample
-New CompiledCuda functionality for run-time compiling and saving of cuda shaders on dev machines
-Cleaner math interface
-User type buffers now work with d3d/ogl interop
-More error detection for d3d Buffers
