D3D_SHADER_VARIABLE_CLASS enumeration (d3dcommon.h)

2022-01-31

Values that identify the class of a shader variable.

Note

For programming with Direct3D 10, this API has a type alias that begins D3D10_ instead of D3D_. These Direct3D 10 type aliases are defined in d3d10.h, d3d10misc.h, and d3d10shader.h.

Syntax

typedef enum _D3D_SHADER_VARIABLE_CLASS {
  D3D_SVC_SCALAR = 0,
  D3D_SVC_VECTOR,
  D3D_SVC_MATRIX_ROWS,
  D3D_SVC_MATRIX_COLUMNS,
  D3D_SVC_OBJECT,
  D3D_SVC_STRUCT,
  D3D_SVC_INTERFACE_CLASS,
  D3D_SVC_INTERFACE_POINTER,
  D3D10_SVC_SCALAR,
  D3D10_SVC_VECTOR,
  D3D10_SVC_MATRIX_ROWS,
  D3D10_SVC_MATRIX_COLUMNS,
  D3D10_SVC_OBJECT,
  D3D10_SVC_STRUCT,
  D3D11_SVC_INTERFACE_CLASS,
  D3D11_SVC_INTERFACE_POINTER,
  D3D_SVC_FORCE_DWORD = 0x7fffffff
} D3D_SHADER_VARIABLE_CLASS;

Constants


`D3D_SVC_SCALAR` Value: 0 The shader variable is a scalar.
`D3D_SVC_VECTOR` The shader variable is a vector.
`D3D_SVC_MATRIX_ROWS` The shader variable is a row-major matrix.
`D3D_SVC_MATRIX_COLUMNS` The shader variable is a column-major matrix.
`D3D_SVC_OBJECT` The shader variable is an object.
`D3D_SVC_STRUCT` The shader variable is a structure.
`D3D_SVC_INTERFACE_CLASS` The shader variable is a class.
`D3D_SVC_INTERFACE_POINTER` The shader variable is an interface.
`D3D10_SVC_SCALAR` The shader variable is a scalar.
`D3D10_SVC_VECTOR` The shader variable is a vector.
`D3D10_SVC_MATRIX_ROWS` The shader variable is a row-major matrix.
`D3D10_SVC_MATRIX_COLUMNS` The shader variable is a column-major matrix.
`D3D10_SVC_OBJECT` The shader variable is an object.
`D3D10_SVC_STRUCT` The shader variable is a structure.
`D3D11_SVC_INTERFACE_CLASS` The shader variable is a class.
`D3D11_SVC_INTERFACE_POINTER` The shader variable is an interface.
`D3D_SVC_FORCE_DWORD` Value: 0x7fffffff This value is not used by a programmer; it exists to force the enumeration to compile to 32 bits.

Remarks

The class of a shader variable is not a programming class; the class identifies the variable class such as scalar, vector, object, and so on. D3D_SHADER_VARIABLE_CLASS-typed values are specified in the Class member of the D3D11_SHADER_TYPE_DESC structure.
