I learned a few new terms today for graphics programming. Pixel is something everyone knows of course but Texel and Voxel are less known.

• A pixel is the single smallest point addressable on your screen.
• A texel is the smallest unit of whatever it is that you are drawing to the screen. It’s pixels are inferred based upon many factors (for example, scaling).
• A voxel is the smallest unit of 3D space that you are drawing. All the voxels being drawn in a 3D object are inferred based upon relation to other voxels (you specify points to define a volume).
