World
- Matrix that holds all Vertices send to video card
View
- frustum of the camera view; near and far clipping plane
Projection
- Flat 2D plane that is interpolated from the 3D View
The video card is handed a list of vertices the vetices are then places in the world. The View is used to see the world and the projection is the actual view surface.
- Vertex Buffer
- Vertex buffer is a list of vertices that are used to make one of the XNA privative shapes.
- VertexDeclaration

Homework
Create a simple 3D Vertex buffer that draws some kind of simple object. You can use points, Triangles, or lines, but no meshes.
