Assembly: Microsoft.Xna.Framework.Graphics (in microsoft.xna.framework.graphics.dll)
The reference value is compared, by the comparison function specified by the StencilFunction property, to the stencil buffer entry of a pixel. This can be illustrated by a simple equation:
ReferenceStencil StencilFunction (stencil buffer entry)
This comparison applies only to the bits in the reference value and stencil buffer entry that are set in the stencil mask by this property. If the comparison is true, the stencil test passes and the pass operation (specified by the StencilPass property) is performed.
