Detailed Description

A TouchSensor node tracks the location and state of the pointing device and detects when the user points at geometry contained by the TouchSensor node's parent group.

As the user moves the bearing over the TouchSensor node's geometry, the point of intersection (if any) between the bearing and the geometry is determined. Each movement of the pointing device, while isOver is TRUE, generates hitPoint_changed, hitNormal_changed and hitTexCoord_changed events. hitPoint_changed events contain the 3D point on the surface of the underlying geometry, given in the TouchSensor node's coordinate system. hitNormal_changed events contain the surface normal vector at the hitPoint. hitTexCoord_changed events contain the texture coordinates of that surface at the hitPoint. The values of hitTexCoord_changed and hitNormal_changed events are computed as appropriate for the associated shape.
