opencl support?

[zoey9628]

Hi!

I want to run it not in nvidia drivers, but in other drivers and I wanted to speed things up. So I want to implement SceneRefineOpenCL.cpp, and I will be glad to do so if you will commit source code of openCL. I will be glad to help with this.

Hi @zoey9628 Great idea adding support for openCL. Two suggestions I'd like to make:

• if you want to reimplement refine mesh algorithm you should use plain openGL shaders, and no CUDA or openCL; first of all I lost the original cuda kernerls for this, second the entire refinement process is just a bunch of triangles rasterization, which is perfect for any rasterization pipeline like OpenGL, or even OpenGL ES which will work on any GPU, including mobile :)
• however the densification algorithm would be a perfect match for porting to OpenCL, so pls try that instead if you really want to use openCL

Thanks a lot for your apply. As you said, I wanted to use openCL in densification algorithm.

• On cpu, densification algorithm take about 35 seconds, so I wanted to speed up the algorithms with openCL. I will give it a try :)

• Refine mesh algorithm take less than 1 second on the cpu, so it is enough to meet my requirements
