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. <p> 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. <p><P><P><DL><DT><B>Since:</B></DT> <DD>Java 3D 1.4</DD></DL><HR><P><!-- ========== METHOD SUMMARY
