Data Types
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 |
| Scalar | One-component scalar |
| 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.
