is a point in 3D space, defined by x,y,z coordinates. Couting: 1 vertex, 2 vertices
Shown are three vertices you need to supply to OpenGL in order to draw a triangle
Vertex coordinates are basically a vector
, therefore vector math
applies to both of them.
Vertex can have normals
, which determine the curvature of the face
near this vertex. The normals are usually interpolated
unless normal map
