Using
displacement without changing the shape of objects
Lightwave's
displacement feature uses an image to displace points along one of the
3 axes (X, Y or Z). In the pin toy example at right, each pin is displaced,
but the pin’s shape is not distorted, as you would normally expect.
To achieve this I used a UV texture for the displacement. Each group
of points, which make up a single pin, has been collapsed to a single
point in the UV map. Therefore all the points in each pin move as a
single unit.
