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.
Get the constant Graph::INode interface. This method returns a constant pointer to the node's Graph::INode interface, to be able to query common node properties such as active state, visibility or ID.
Murl.Graph.INode GetNodeInterface()
Get the constant Graph::ITransform interface. This method returns a constant pointer to the node's Graph::ITransform interface, to be able to query the node's transformation matrix and depth order.
Murl.Graph.ITransform GetTransformInterface()
Get the constant Graph::ILightNodeTarget container. This method returns a constant pointer to the node's Graph::ILightNodeTarget container, which allows to query the light this transform node refers to.
Murl.Graph.IGenericNodeTarget.GraphILight GetLightNodeTarget()
Get the constant Graph::IAnchorNodeTarget container for the target position. This method returns a constant pointer to the node's Graph::IAnchorNodeTarget container, which allows to query the referenced Graph::IAnchor node used as a view target.
Murl.Graph.IGenericNodeTarget.GraphIAnchor GetAnchorNodeTarget()
Set the target anchor up vector. The up vector is used to orient the view when a target anchor node is given.
Boolean SetUpVector(Murl.Math.Vector upVector)
upVector | The up vector. |
Get the target anchor up vector.
