The ICameraTransform graph node interface.
A camera node defined in the scene graph only defines the general behavior of a camera in the virtual world; to be able to move and rotate the camera, it is necessary to define an ICameraTransform node that refers to a specific camera. By separating a camera from its transform, it is possible to already use a camera before its actual world position and rotation are evaluated; this way, the camera can be quickly attached to e.g. a moving object that is supposed to be also visible throught that camera, by simply defining an ICameraTransform node as a child of the respective object.
See Graph::ICamera for defining a specific camera for rendering.
See Graph::ICameraState for activating a camera 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::ICameraNodeTarget container. This method returns a constant pointer to the node's Graph::ICameraNodeTarget container, which allows to query the camera this transform node refers to.
Murl.Graph.IGenericNodeTarget.GraphICamera GetCameraNodeTarget()
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.
Murl.Math.Vector GetUpVector()
