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. http://duoduokou.com/csharp/37722994462387354608.html
