Intro To 3D
Vectors : Vector3 x , y , z
Right handed vs Left Handed Coordinate Systems RHCS and LHSC
Matrices: A matrix is a class that is used to transform vectors.
High Level Shader Language
HLSL pathway to Hardware.
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 vertices 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.

Matrices can be multiplied together to combine the effects to their translation. The order in which you combine them does matter.
- I Identity
- S Scale
- R Rotate
- T Translate
- O Orbit

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