Vertices in 3D
In Chapter 7, you learned that a vertex has a few attributes:
- Position
- Color (optional)
- Texture coordinates (optional)
- You created a helper class called
Vertices, which handles all the dirty details for you. You limited the vertex positions to have only x- and y-coordinates. All you need to do to go 3D is modify theVerticesclass so that it supports 3D vertex positions.
Vertices3: Storing 3D Positions
Let's write a new class called Vertices3 to handle 3D vertices based on your original Vertices class. Listing 10–1 shows the code.
