Comparison options.

Syntax

typedef enum D3D10_COMPARISON_FUNC {
  D3D10_COMPARISON_NEVER = 1,
  D3D10_COMPARISON_LESS = 2,
  D3D10_COMPARISON_EQUAL = 3,
  D3D10_COMPARISON_LESS_EQUAL = 4,
  D3D10_COMPARISON_GREATER = 5,
  D3D10_COMPARISON_NOT_EQUAL = 6,

} ;

Constants

 
D3D10_COMPARISON_NEVER
Value: 1
Never pass the comparison.
D3D10_COMPARISON_LESS
Value: 2
If the source data is less than the destination data, the comparison passes.
D3D10_COMPARISON_EQUAL
Value: 3
If the source data is equal to the destination data, the comparison passes.
D3D10_COMPARISON_LESS_EQUAL
Value: 4
If the source data is less than or equal to the destination data, the comparison passes.
D3D10_COMPARISON_GREATER
Value: 5
If the source data is greater than the destination data, the comparison passes.
D3D10_COMPARISON_NOT_EQUAL
Value: 6
If the source data is not equal to the destination data, the comparison passes.
D3D10_COMPARISON_GREATER_EQUAL
Value: 7
If the source data is greater than or equal to the destination data, the comparison passes.
D3D10_COMPARISON_ALWAYS
Value: 8
Always pass the comparison.

Remarks

A comparison option determines whether how the runtime compares source (new) data against destination (existing) data before storing the new data. The comparison option is declared in a description before an object is created. The API allows you to set a comparison option for a depth-stencil buffer (see D3D10_DEPTH_STENCIL_DESC), depth-stencil operations (see D3D10_DEPTH_STENCILOP_DESC), or sampler state (see D3D10_SAMPLER_DESC).
