vertex

Point in space, usually a point in a mesh model. A vertex can be both a 3D or 2D point. Not to confuse with vector allthough conversion can be done. A vertex usually contains more than just a position. It can also contain color, mapping coordinates, normals and other properties. One vertex - Many vertices. Typical vertex definition in C: struct vertex { float x; float y; float z; float nx; float ny; float nz; int color; float u; float v; } Three or more vertices makes a polygon, if connected.
