This function determines whether a particular pixel will be drawn based on the contents of the stencil buffer at that location. The formula is <tt>StencilFunction([[NiStencilPropertyGetStencilMask|mask]] & buffer value, mask & [[NiStencilPropertyGetStencilRef|ref]])</tt>. Thus, assuming the default mask value of <tt>0xFFFFFFFF</tt>, a StencilFunction value of 1 (<tt>LESS</tt>)would mean that the stencil property tests <tt>value < ref</tt>, and if true, draws the pixel in question. | This function determines whether a particular pixel will be drawn based on the contents of the stencil buffer at that location.
