Let's walk through the major stages of this pipeline from start to finish:
- Vertex specification: In the first stage, the vertices of the drawing are determined by your application. A vertex is essentially a point in a 3D space that can be used to draw a shape. The vertex may also contain metadata about the point, such as its color.
