Opengl fragment shader example

WebYou can grab the full example program here, but the important files are main.cpp and opengl_cs.cpp. In main.cpp we create an OpenGL 4.3 context (I'm being strict and using a forward-compatible core profile, but you don't have to), a texture for the compute shader to write and the fragment shader to read, and two program objects. Web9 de nov. de 2015 · 1 Answer. Sorted by: 5. This is a pixelation shader, it seems. What it does is, it divides the screen into tiny rectangles, the side of each rectangle is determined by the values dx and dy. The smaller the value of pixels, the more pixelated the screen is, as that increases the size of dx and dy and thus the size of the rectangles.

In the previous example we saw how to transform the geometry sent from the application to draw a model with a color defined as a constant in the fragment shader. In here we’re going to explore some more flexible ways of setting color for a 3D model. The first approach is to consider color as a vertex attribute.
