Realtime Rendering Assignment 4 at Trinity College Dublin. This video demonstration shows the 6 different texture minification methods offered by OpenGL when applying a texture to an object. The first 2: GL_NEAREST and GL_LINEAR do not generate mipmaps and perform the worst. The last 4: GL_NEAREST_NEAREST, GL_NEAREST_LINEAR, GL_LINEAR_NEAREST and GL_LINEAR_LINEAR do generate mipmaps and perform progressively better in the order I've listed them in above. Also included is an anisotropic filtering parameter that I change between 2x, 4x, 8x and 16x to demonstrate how anisotropic filtering can be used to improve poor texture sampling at long distances. This demonstration takes place on a flat checkerboard plane, a sloped checkerboard landscape and on various other 3D models placed further and further away from the camera to demonstrate the aliasing affects that occur as objects move further and further away from the camera.
