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.
explicit OccluderNode(std::string const &name)
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
Returns the minimum screen coverage.
std::size_t get_num_vertices(void) const
Returns the number of vertices in the occluder polygon. This should always return 4.
Is this occluder double-sided
void set_double_sided(bool value)
If true, the back-face will also be used to occlude
void set_min_coverage(PN_stdfloat value)
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.
