D3D_SHADER_VARIABLE_CLASS enumeration (d3dcommon.h)

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.
