In the first lecture the professor mentioned that everything we see in computer graphics can be made up of triangles. All shapes can be made up of many many triangles. How do these triangles associate with the pixel Area? Are the pixels forming many many triangles?

@ laurenz06 It seems that the rasterization process essentially breaks down the continuous 2D triangles into discrete pixels, and the shading and color information for each pixel are determined based on the attributes of the corresponding 3D triangle. I don't think the pixels themselves are forming triangles, but I do believe that triangles are a fundamental building block in computer graphics in general since they are simple to work with and can approximate a wide range of shapes and surfaces.
