WebA simple OGL 4.0 GLSL shader program that shows how to map a 2D texture on a mesh. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. The texture matrix defines how the texture is mapped on the mesh. By manipulating the texture matrix, the texture can be displaced, scaled and rotated. WebIf I Know GLSL, 5 What Do I Need to Do Differently to Write a Compute Shader? Not much: 1.
