C++ 3D

I am using C++, and moving on to doing 3D things with it. I've some good experience with Java3D's API.

My question: OpenGL / DirectX / ???someothersuggesteions???

Leaning more so to OpenGL. I've heard a bit about Ogre3D too.

Well, the great thing about doing graphics through OpenCL or DirectCompute is that they are based off of ISO C99, with extensions for doing SIMD math, steaming data to/from buffers, and coordinating GPU threads and wavefronts. For someone who used to do demo coding on Amiga and DOS, this level of control on the GPU is very enticing to demoscene coders in a nostalgic sense as it finally makes doing software rendering practical again. There's lot of people experimenting with custom GPGPU ray-tracers, ray-casters, deferred shaders, and more esoteric types of graphical methods and data-structures that were previously confined to non-realtime.
