java.lang.Object javax.media.j3d.PickInfo.IntersectionInfo
public class PickInfo.IntersectionInfo
The IntersectionInfo object holds extra information about an intersection of a PickShape with a Node as part of a PickInfo. Information such as the intersected geometry, the intersected point, and the vertex indices can be inquired. The local coordinates, normal, color and texture coordiantes of at the intersection can be computed, if they are present and readable, using the interpolation weights and vertex indices.
If the Shape3D being picked has multiple geometry arrays, the possible arrays of IntersectionInfo are stored in the PickInfo and referred to by a geometry index. If the picked geometry is of type, Text3D or CompressGeometry, getVertexIndices is invalid. If the picked Node is an Morph object, the geometry used in pick computation is alway at index 0.
Method Summary  

double 
getDistance()
Retrieves the distance between the start point of the pickShape and the intersection point. 
Geometry 
getGeometry()
Retrieves the reference to the intersected geometry in the picked object, either a Shape3D or Morph. 
int 
getGeometryIndex()
Retrieves the index to the intersected geometry in the picked node, either a Shape3D or Morph. 
Point3d 
getIntersectionPoint()
Retrieves the reference to the intersection point in the pickable node. 
int[] 
getVertexIndices()
Retrieves the vertex indices of the intersected primitive in the geometry.
