Detailed Description

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.

Member Function Documentation

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

Definition at line 143 of file TransformNode.cc.

void ACG::SceneGraph::TransformNode::setIdentity ( )

virtual

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.
