I am trying to do some raytracing in OpenGL via the compute shader and I came across a weird problem. At the moment I just want to display a sphere without any shading. My compute shader launches a ray for every pixel and looks like this: #version 430 struct Sphere{ vec4 position; float radius; }; struct Ray{ vec3 origin; vec3 dir; }; uniform ...

Opengl and glsl can be used for both ray and path tracing if you are really good at it. however there are few other better options like Nvidia optix with Cuda toolkit, directx 12, vulkan ray tracing, metal, falcor. Note that, all these are low level APIs that could be good performance with Nvidia recent rtx technology and support multi gpus Share

My results doing ray tracing in the fragment shader : opengl

The vertex shader therefore can be made to simply pass a point on a plane at z=-1 in camera space to the fragment shader. Normalise (this point - the origin) and you have a ray direction and origin already calculated. Just pass through the world triangle data and do all intersection tests and ray spawning in the fragment shader itself.
