• Texel - element of a texture
• Mipmap - pre-calculated impages that accompany a main image (MIP = multum in parvo == latin for much in a small space)
• Anisotropic - direction dependent (vs. isotropic - homogenity in all directions)
• Anisotropic mipmap - ? using higher resolution textures for directions where more details is needed ?

• Bilinear filtering - smooths textures that are smaller or larger than actual size - interpolating among the 4 texels nearest the output pixel
• Trilinear filtering - does linear interpolation between mipmaps
  1. do bilinear filtering on 2 mipmaps closest to the desired size
  2. interpolate between the 2
