shader - Random noise functions for GLSL - Stack Overflow NB: Nowadays GLSL have integers, so there is no longer any reason not to use "serious" int-based hash generators when quality distribution (and dynamics) is required, with similar performances ( excepted for very low-end devices )
What is the difference between opengl and GLSL? GLSL is a higher-level language that can be compiled and run on graphics hardware So to sum it all up, programmable shaders are an integral part of the OpenGL framework (or any modern graphics API), and GLSL makes it vastly easier to program them

opengl - Get supported GLSL versions - Stack Overflow Meanwhile, I want to check what GLSL versions the current driver card supports, so I use this: glGetString ( GL_SHADING_LANGUAGE_VERSION ) Which, to my dismay, returns only "1 30" How can I get the full list? Or even if it's not the full list, how can I get standard GL supported versions, and GLES supported versions?
c++ - OpenGL bool uniform? - Stack Overflow I'm trying to send a boolean to an OpenGL glsl shader Currently I have this in the shader: uniform bool foo; And I use this to set it: glUniform1i(glGetUniformLocation(shader, "foo"), true); Th
glsl - How to do ray tracing in modern OpenGL? - Stack Overflow Opengl (glsl) can be used for ray (path) tracing however there are few better options: Nvidia OptiX (Cuda toolkit -- cross platform), directx 12 (with Nvidia ray tracing extension DXR -- windows only), vulkan (nvidia ray tracing extension VKR -- cross platform, and widely used), metal (only works on MacOS), falcor (DXR, VKR, OptiX based
