Didn't watch the whole video yet (I'm at 2:46) but damn I never heard about this technique ray casting. So does it mean that it only computes the first object that hits the ray and discard anything behind that first object?

It's really good for fast rendering. Yeah it discards anything behind it and only uses the first object for the color.

@@voxelbee Having never programmed a GPU, I was not clear on the distinction between C++ and GPU programming. Is this written in GPU programming(shaders?) or C++ or both? How much of the time is executed by CPUs vs. GPUs? Also, I don't know the difference between multithreading/multicore programming on GPUs vs. multithreaded/multicore CPUs.

@voxelbee 3 жыл бұрын

@@yvindharboe7048 Yeahh so all of the rendering is done on the GPU using shaders this takes about half of the current frame time or less. Then the CPU is generating the scene and sending that to the GPU this could be done in multiple threads speeding up the scene generation time and therefore the FPS.

@geekonarium 3 жыл бұрын

If you divide all voxels into groups, couldn't raytracing skip certain regions if they are empty? Maybe 10 times 10 voxels in a group. And then you could divide these groups into larger groups again? These groups has a flag if they are empty or not. Also light rays could overjump empty cells. Would this bring any performence benefits? Just guessing. Sorry for the noob question :-)

@voxelbee 3 жыл бұрын

Currently it is implemented using octree ray casting so this does mean the rays skip over empty space very quickly! Very similar to what you said about groups of voxels!
