Detailed Description

The H3DCoordinateDeformerNode is the abstract base class for all nodes specifying deformation of coordinates based on contact of haptics devices.

All subclasses are required to implement the deformPoints method to specify how the coordinates should be deformed.

For usages of the node type, see DeformableShape.

virtual string H3D::H3DCoordinateDeformerNode::defaultXMLContainerField (   )  [inline, virtual]

Returns the default xml containerField attribute value. For this node it is "deformer". Reimplemented from H3D::Node.

virtual void H3D::H3DCoordinateDeformerNode::deformPoints (  const vector< bool > &  is_touched, const vector< Vec3f > &  touch_point, const vector< Vec3f > &  touch_normal, const vector< Vec3f > &  touch_force, const vector< Vec3f > &  penetration_points, const vector< Vec3f > &  orig_points, const vector< Vec3f > &  resting_points, const vector< Vec3f > &  deformed_points, vector< Vec3f > &  new_resting_points, vector< Vec3f > &  new_deformed_points )  [pure virtual]

The deformPoints method determines the deformation of coordinates based on the interaction of a haptics device. The is_touched, touch_points, touch_normal and touch_force parameters all are vectors of the same size, where the first value in the vector is the value for haptics device 0, the second for haptics device 1, and so on. Parameters: is_touched  Specifies if a haptics device is in contact or not. touch_point  The contact point in local coordinates for each device. touch_normal  The normal at the contact point for each device. touch_force  The force with which the surface is pressed for each device. penetration_points  The weightedProxyPosition of each device. orig_points  The original points before any deformation. resting_points  The resting coordinates (see DeformableShape) deformed_points  The deformed coordinates (see DeformableShape) new_resting_points  Output parameter that specifies the new resting coordinates after the deformation. If no changes are made to the resting coordinates, return an empty vector. new_deformed_points  Output parameter that specifies the new deformed coordinates after the current deformation. If no changes are made to the deformed coordinates, return an empty vector. Implemented in H3D::CoordinateDeformer.
