Member Function Documentation

Vec3d ACG::SceneGraph::ManipulatorNode::direction

(

)

const

Get direction in world coordinates. Will take the current rotation into account.

Definition at line 584 of file ManipulatorNode.cc.

void ACG::SceneGraph::ManipulatorNode::set_direction

(

Vec3d &

_v

)

Set direction in world coordinates. Will take the current rotation into account.

Definition at line 574 of file ManipulatorNode.cc.

void ACG::SceneGraph::ManipulatorNode::setIdentity ( )

virtual

set the current transformation to the identity transformation, i.e. change the center() to the transfomed center and loadIdentity().

Reimplemented from ACG::SceneGraph::TransformNode.

Definition at line 118 of file ManipulatorNode.cc.

bool ACG::SceneGraph::ManipulatorNode::touched ( )

inline

if the manipulator node has been clicked by the mouse, this function will return true. Use reset_touched to reset this flag
