This enumeration provides values used to identify actions that the Direct3D Mobile pixel pipeline will take as the result of a stencil test. For more information, see Stencil Operations.

Syntax

typedef enum _D3DMSTENCILOP {
  D3DMSTENCILOP_KEEP        = 1,
  D3DMSTENCILOP_ZERO        = 2,
  D3DMSTENCILOP_REPLACE     = 3,
  D3DMSTENCILOP_INCRSAT     = 4,
  D3DMSTENCILOP_DECRSAT     = 5,
  D3DMSTENCILOP_INVERT      = 6,
  D3DMSTENCILOP_INCR        = 7,
  D3DMSTENCILOP_DECR        = 8,
  D3DMSTENCILOP_FORCE_ULONG = 0x7fffffff,
} D3DMSTENCILOP;

Elements

  • D3DMSTENCILOP_KEEP
    Indicates that the stencil buffer will not be updated.
  • D3DMSTENCILOP_ZERO
    Indicates that the stencil buffer value for the given pixel will be set to 0.
  • D3DMSTENCILOP_REPLACE
    Indicates that the stencil buffer value for the given pixel will be set to the stencil reference value.
  • D3DMSTENCILOP_INCRSAT
    Indicates that the stencil buffer value for the given pixel will be incremented by 1. The stencil buffer value is limited to 2^n, where n is the number of bits in the stencil buffer channel.
  • D3DMSTENCILOP_DECRSAT
    Indicates that the stencil buffer value for the given pixel will be decremented by 1. The stencil buffer value cannot be set to a value less than 0.
  • D3DMSTENCILOP_INVERT
    Indicates that the bits of the stencil buffer value for the given pixel will all be inverted.
  • D3DMSTENCILOP_INCR
    Indicates that the stencil buffer value for the given pixel will be incremented by 1 with all overflow bits thrown away. As a result the stencil buffer value will wrap around to 0.
  • D3DMSTENCILOP_DECR
    Indicates that the stencil buffer value for the given pixel will be decremented by 1 with all underflow bits thrown away. As a result the stencil buffer value will wrap around to 2^n, where n is the number of bits in the stencil channel.
  • D3DMSTENCILOP_FORCE_ULONG
    Forces the compiler to interpret the enumeration as a ULONG value. This value is not used directly in Direct3D Mobile programming.

Remarks

Stencil-buffer entries are integer values ranging from 0 to 2n –1, where n is the bit depth of the stencil buffer.
