Glsl c++

Rendering the shadow map. The basic of shadow mapping is that we render the scene first as the light source would be the camera. In order to do that we create two View matrices and two Projection matrices, one for the light source and one for the camera. In the first step we pass the light source MVP matrix to the shaders.

Glsl c++. glReadPixels always returns the same value in glClearColor. I've been struggling to understand the output of glReadPixels, which appears to be straightforward in theory, but actually produces puzzling (at least to me) results. Let's assume I have a simple fragment shader that draws a single triangle with a color value of vec4 (0.2, 0, 0, 0 ...

My suggestion would be to make the incorporation of shader into your binary a part of your build process. I use CMake in my code to scan a folder for shader source files and then generate a header with an enum of all the available shaders: #pragma once enum ShaderResource { LIT_VS, LIT_FS, // ...

Parallax Occlusion Mapping. In general terms, we can consider that parallax mapping is a ‘shading hack’ it means that it works only on the “VIEW” side of things and is practically useless in the general context of Blender toolset.
