HLSL supports many different intrinsic data types. This table shows which types to use to define shader variables.
|Use This Intrinsic Type||To Define This Shader Variable|
|Buffer||Buffer, which contains one or more scalars|
|Vector, Matrix||Multiple-component vector or matrix|
|Sampler, Shader, Texture||Sampler, shader, or texture object|
|Struct, User Defined||Custom structure or typedef|
To help you better understand how to use vectors and matrices in HLSL, you may want to read this background information on how HLSL uses per-component math.
