class
OccluderNode¶ Bases:
PandaNodeA 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.
Inheritance diagram
-
__init__(name: str) → None¶ The default constructor creates a default occlusion polygon in the XZ plane (or XY plane in a y-up coordinate system). Use the normal Panda set_pos(), set_hpr(), set_scale() to position it appropriately, or replace the vertices with
setVertices().
-
setDoubleSided(value: bool) → None¶ If true, the back-face will also be used to occlude
-
isDoubleSided() → bool¶ Is this occluder double-sided
-
setMinCoverage(value: float) → None¶ 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.
-
getMinCoverage() → float¶ Returns the minimum screen coverage.
-
setVertices(v0: LPoint3, v1: LPoint3, v2: LPoint3, v3: LPoint3) → None¶ 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.
-
getNumVertices() → size_t¶ Returns the number of vertices in the occluder polygon. This should always return 4.
- Return type
size_t
-
getVertex(n: size_t) → LPoint3¶ Returns the nth vertex of the occluder polygon.
- Return type
LPoint3
-
setVertex(n: size_t, v: LPoint3) → None¶ Sets the nth vertex of the occluder polygon.
-

getClassType() → TypeHandle¶ - Return type
-
getVertices() → list¶

- Setter
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.
