CrazyBump
may not be the first utility that might spring to mind as a
CNC application. However,it
can be employed to rapidly create excellent quality sources
for height-mapped engraving or model generation purposes.
CrazyBump
has the unique ability to "stack" normal or displacement
maps, with
many options available in respect of combining map effects.
A Recent
development is the move to "Demo" rather than "Beta" status. This
utility will eventually emerge as a full-blown commercial
application for 3D modellers. Click the image to access the
