StencilAttrib

from panda3d.core import StencilAttrib
class StencilAttrib

Bases: RenderAttrib

A StencilAttrib is a collection of all stencil render states. The render states in a StencilAttrib are read-only. A StencilAttrib is created with make or make2Sided(). To determine if two sided stencil is supported, call the function GraphicsStateGuardian:: get_supports_two_sided_stencil.

static makeDefault()RenderAttrib

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

static makeOff()RenderAttrib

Constructs a StencilAttrib that has stenciling turned off.
