The ILightTransform graph node interface. More...
#include <murl_graph_i_light_transform.h>
The ILightTransform graph node interface.
A light node defined in the scene graph only defines the general parameters of a light in the virtual world; to be able to position and rotate the light, it is necessary to define an ILightTransform node that refers to a specific light. By separating a light from its transform, it is possible to already use a light before its actual world position and rotation are evaluated; this way, the light can be quickly attached as a child to e.g. a moving object that is supposed to be also influenced by that light.
See Graph::ILight for defining individual light sources and their group assignment.
See Graph::ILightState for activating lights for rendering.
