Cropping
- Cropping is a method for exploring a solid
or a set of isosurfaces by showing only that portion
that lies on one side of a cropping plane. (How to crop)
- Model Viewer implements three pairs of cropping
planes, denoted as the x, y, and z.
- By default, the pair of x cropping planes is
perpendicular to the x axis, and similarly for the y and z cropping planes.
- However, the x and y cropping planes may also be
rotated.
- When cropping is enabled, only the portion between a pair
of cropping planes is displayed.
- The locations of the pair of x cropping planes, in
their unrotated state, are specified as x =
value1 (Min position) and x = value2 (Max position), where value1
is less than or equal to value2. The locations of the pair of y and z cropping
planes are specified similarily. Note that the x, y, and z are
normalized coordinates.
The figure below illustrates cropping a solid using the
pair of y cropping planes at y =
0.3 (Min position) and y = 0.7
(Max position).

The figure below illustrates cropping a set of
isosurfaces using the pair of y cropping planes at y =
0.3 (Min position) and y =
0.7
(Min position).
