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. Web7 de fev. de 2016 · Rasterization.

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.
