OccluderEffect

class OccluderEffect

Bases: RenderEffect

This functions similarly to a LightAttrib or ClipPlaneAttrib. It indicates the set of occluders that modify the geometry at this level and below. Unlike a ClipPlaneAttrib, an OccluderEffect takes effect immediately when it is encountered during traversal, and thus can only add occluders; it may not remove them.

OccluderEffect.add_on_occluder()

Returns a new OccluderEffect, just like this one, but with the indicated occluder added to the list of occluders enabled by this effect.

static OccluderEffect.get_class_type()

OccluderEffect.get_num_on_occluders()

Returns the number of occluders that are enabled by the effectute.

OccluderEffect.get_on_occluder()

Returns the nth occluder enabled by the effectute, sorted in render order.

OccluderEffect.has_on_occluder()

Returns true if the indicated occluder is enabled by the effect, false otherwise.

OccluderEffect.is_identity()

Returns true if this is an identity effect: it does not change the set of occluders in use.

static OccluderEffect.make()

Constructs a new OccluderEffect object that does nothing.

OccluderEffect.remove_on_occluder()

Returns a new OccluderEffect, just like this one, but with the indicated occluder removed from the list of occluders enabled by this effect.
