CUDA-将OpenGL渲染的图像复制到2D数组

Question

Is it possible, to render a scene using OpenGL and than somehow copy rendered image to, for example, 2D array using CUDA? I'd need to place a result in bool picture[resX][resY] array, where true = coloured pixel, false = empty space.

Thanks is advance for any suggestions!

Answer 1

You could render to a PBO in OpenGL and then subsequently map this to a CUDA texture. Have a look at the OpenGL interop documentation for some pointers
