NiStencilPropertySetStencilFunction
This is a command from NifSE.
Syntax
(bool:success) NiStencilPropertySetStencilFunction short:stencilFunc short:nifID short:blockID (bool:success) NiStencilPropSetFunc short:stencilFunc short:nifID short:blockID
Sets the function used by the NiStencilProperty specified by blockID. The possible values and their meanings are indicated below.
Returns 1 if successful, 0 otherwise.
The default value of blockID, 0, indicates the NIF's root, a NiNode. NiNode blocks are not derived from NiStencilProperty, so this function will always require an explicit blockID.
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
