TransformNode - general 3D geometric transformation node. Provides functionality to translate, scale or rotate around a specified center. This is the base class for e.g. the TrackballNode and the ManipulatorNode, that only add a GUI for generating the transformations.
Note that in order for the transformations to apply in each traversal of the scenegraph, one has to call apply_transformation(true) once.
Definition at line 95 of file TransformNode.hh.
| void ACG::SceneGraph::TransformNode::loadIdentity | ( | ) |
Reset transformation to identity, i.e. reset rotation, translating and scaling factor.
Definition at line 97 of file TransformNode.cc.
| void ACG::SceneGraph::TransformNode::rotate | ( | double | _angle, |
| const Vec3d & | _axis | ||
| ) |
Add a rotation to the current Transformation. Assume angle in degree and axis normalized

set the current transformation to the identity transformation, i.e. change the center() to the transfomed center and loadIdentity().
Reimplemented in ACG::SceneGraph::TranslationManipulatorNode, ACG::SceneGraph::TrackballNode, and ACG::SceneGraph::ManipulatorNode.
