QueryLat

DESCRIPTION

This module responds to pick mouse button events by determining the lattice value at the first pick intersection and creating text geometry with the value at that location. To use the module, wire a lattice into the input port, wire the Render pick output into the input port, and wire the output geometry into the Render input port.

The value will be displayed while the mouse button is held down and will disappear when the mouse button is released. Trilinear interpolation is used between lattice samples. If the pick location is not within the bounds of the lattice, no geometry will be created.
