Detailed Description

Use a manipulator to translate and scale the children of this node.

Definition at line 90 of file TranslationManipulatorNode.hh.

Member Enumeration Documentation

enum ACG::SceneGraph::TranslationManipulatorNode::ActiveRotations

enum to define which rotation axis should be enabled

This enum defines which rotation axis rings will be visible and available for picking. The modes can be combined.

Definition at line 121 of file TranslationManipulatorNode.hh.

enum ACG::SceneGraph::TranslationManipulatorNode::ManipulatorMode

enum to define the manipulator mode

This enum defines several modes of the manipulator.

TranslationRotation: Full featured mode, rotations and translations will be possible
LocalRotation: The manipulator can be rotated, but no transformation is applied to the child node (use to re-align manipulator)
Resize: No rings, no rotation. The manipulator scales along each axis seperatly. Center sphere scales uniformly in all directions
Place: –
