Member Function Documentation
◆ get_class_priority()
|
virtual |
Returns the relative priority associated with all lights of this class.
This priority is used to order lights whose instance priority (get_priority()) is the same–the idea is that other things being equal, AmbientLights (for instance) are less important than DirectionalLights.
Implements Light.
Definition at line 95 of file rectangleLight.cxx.
◆ get_specular_color()
|
inlinefinalvirtual |
Returns the color of specular highlights generated by the light.
This is usually the same as get_color().
Reimplemented from Light.
Definition at line 37 of file rectangleLight.I.
References Light::get_color.
◆ make_copy()
|
virtual |
Returns a newly-allocated PandaNode that is a shallow copy of this one.
It will be a different pointer, but its internal data may or may not be shared with that of the original PandaNode. No children will be copied.
Reimplemented from Camera.
Definition at line 75 of file rectangleLight.cxx.
◆ register_with_read_factory()
|
static |
Tells the BamReader how to create objects of type RectangleLight.
Definition at line 110 of file rectangleLight.cxx.
References BamReader::get_factory(), and Factory< Type >::register_factory().
Referenced by init_libpgraphnodes().
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from LightLensNode.
Definition at line 119 of file rectangleLight.cxx.
References BamWriter::write_cdata(), and LightLensNode::write_datagram().
Member Data Documentation
◆ get_max_distance
|
inline |
Returns the maximum distance at which the light has any effect, as previously specified by set_max_distance.
Definition at line 44 of file rectangleLight.h.
◆ set_max_distance
|
inline |
Sets the radius of the light's sphere of influence.
Beyond this distance, the light may be attenuated to zero, if this is supported by the shader.
