WebGLSL Tutorial – Color Example. 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. WebIn Fragment Shaders, there is one other circumstance that can remove implicit derivatives: non-uniform flow control. Uniform flow control for a particular location in code means …
