List of the stencil functions used by NiStencilProperty blocks. Used by NifSE.
Stencil Functions
This function determines whether a particular pixel will be drawn based on the contents of the stencil buffer at that location. The formula is StencilFunction(mask & buffer value, mask & ref). Thus, assuming the default mask value of 0xFFFFFFFF, a StencilFunction value of 1 (i.e. LESS) would mean that the stencil property tests value < ref, and if true, draws the pixel in question.
- NEVER = 0
- LESS = 1
- EQUAL = 2
- LEQUAL = 3
- GREATER = 4
- NOT_EQUAL = 5
- GEQUAL = 6
- ALWAYS = 7
