GPU, Matrices

See Sections 1 and 2 of my Tutorial. It refers to a language (HLSL) used to describe shaders. For the time being, we only set some values from the outside. Important points: data flow on a GPU; z-buffer; linear perspective, homogeneous coordinates. Note that XNA Game Studio uses a right-handed coordinate system, unlike pure DirectX.

XNA Game Studio does no longer support the old "configurable" 3D pipeline without shaders; it requires the use of shader programs, the so-called "programmable" 3D pipeline. However, there are "basic effects" that can be used with no shader programming.
