This weekend I’ve started the process of getting Voxeliens to run under OpenGL as well as Direct3D. A large part of this transition is handled automatically as we use Ogre as our rendering system and it already has support for both APIs. However, we do need to convert all our HLSL shaders into GLSL versions.

So far this transition is going fairly smoothly, and the screenshot below is taken from the new OpenGL version. As you can see, the voxel colours are coming through but the lighting and shadows are missing. Shadows are probably going to be the trickiest part but hopefully it will come together over the next week of so.

Although I’m still working on Windows, the motivation behind the OpenGL version is to allow the port to Linux. Stay tuned for further updates!
