OccluderNode

class OccluderNode

Bases: AcronNode

A node in the scene graph that can hold an occluder polygon, which must be a rectangle. When the occluder is activated with something like render.set_occluder(), then objects whose bouding volume lies entirely behind the occluder will not be rendered.

OccluderNode.__init__()

The default constructor creates a default occlusion polygon in the XZ plane (or XY plane in a y-up coordinate system). Use the normal Acron set_pos(), set_hpr(), set_scale() to position it appropriately, or replace the vertices with set_vertices().

static OccluderNode.get_class_type()

OccluderNode.get_min_coverage()

Returns the minimum screen coverage.

OccluderNode.get_num_vertices()

Returns the number of vertices in the occluder polygon. This should always return 4.

OccluderNode.get_vertex()

Returns the nth vertex of the occluder polygon.

OccluderNode.is_double_sided()

Is this occluder double-sided

OccluderNode.set_double_sided()

If true, the back-face will also be used to occlude

OccluderNode.set_min_coverage()

Minimum screen coverage needed before occluder used. Range should be 0 to 1. For example, setting to 0.2 would mean that the occluder needs to cover 20% of the screen to be considered.

OccluderNode.set_vertex()

Sets the nth vertex of the occluder polygon.

OccluderNode.set_vertices()

Replaces the four vertices of the occluder polygon. The vertices should be defined in a counterclockwise orientation when looking at the face of the occluder.
