I am just watching the Shaders intro video from here where the Youtube is saying 3 vertices make up a triangle and Could generate a couple hundred fragments based on how much of the screen that triangle occupies Its super easy to understand the first thing but the next thing fragment? What actually the fragment is? W... | What is a fragment in a fragment shader? Wikipedia says that: In general, a fragment can be thought of as the data needed to shade the pixel, plus the data needed to test whether the fragment survives to become a pixel (depth, alpha, stencil, scissor, window ID, etc.) So is it textures, vertices or something else... | "A flea hops randomly on the vertices of a triangle with vertices labeled 1,2 and 3, hopping to each of the other vertices with equal probability. If the flea starts at vertex 1, find the probability that after n hops the flea is back to vertex 1." Could someone provide a hint to help me start this? | eng_Latn | 10,350 |
