Summary

Textures are used to add details and enhance realism in rendering by mapping 2D images to polygons, composed of 2D "texels". Texture coordinates are introduced as an additional component to geometry, with conventions varying between Direct3D/XNA and OpenGL/Unity. Texture mapping examples demonstrate how textures are applied to objects, with considerations for perspective correction and repeated textures. Magnification and minification techniques, such as nearest point sampling, averaging, and bilinear filtering, are used to handle cases where texel and pixel mapping is not 1-to-1. Mip-mapping and tri-linear filtering using mipmaps improve performance and detail for far and close-by objects. Anisotropic filtering preserves details for oblique viewing angles, but is computationally expensive.
