Is it possible to use hardware acceleration in OpenCL
I built a small game engine using OpenCL and SDL2 but it's not running really fast compare to Vulkan and OpenGL. I wrote rasterization code, but when I did some research Vulkan and OpenGL use hardware ...

How to balance GPU compute usage against render usage?
The GPU's primary purpose, obviously, is to render the scene.
However, if we use compute capabilities on the very same GPU, how do we partitition and control these calls such that they do not ...

Synchronization between several glDispatchCompute with same SSBOs
Let's say I have one compute shader A which writes to an SSBO, and then a second compute shader B which reads from the same SSBO.
Do I need to do anything special to ensure that A has finished ...

How do I build a 3D array result set from a compute shader in unity?
I took this right down to the absolute most basic scenario but for some reason I can't get anything back from the GPU when this completes, could someone explain what I am doing wrong ...
Here's my ...

Are GPU physics implementations branchless?
I've implemented MPR on the CPU and in pixel shaders (long story!) and there seems to be unavoidable conditional loops both to find the starting portal as well as to find the final solution. I know ...

a flexible data structure for geometries
What data structure would you use to represent meshes that are to be altered (e.g. adding or removing new faces, vertices and edges), and that have to be "studied" in different ways (e.g. finding all ...
