7. Transform Modules
The modules in the "Transforms" category implement various coordinate transformations. They have
inputs corresponding to the X, Y, and (in some cases) Z coordinates of a point, and outputs giving
the coordinates of the same point in a different coordinate system.
Linear
This module implements an arbitrary linear coordinate transformation. This can consist of any
collection of translations, rotations, and scalings. Double-click the module to bring up a
window in which you can specify the translation, rotation, and scale along each of the three
coordinate axes.
Polar
This module transforms from rectangular to polar or cylindrical coordinates. It has input ports
for the X and Y coordinates of a point, and outputs the corresponding polar coordinates R and
Theta.
Spherical
This module transforms from rectangular to spherical coordinates. It has input ports for the
X, Y, and Z coordinates of a point, and outputs the corresponding spherical coordinates R,
Theta, and Phi.
Jitter
This module outputs a "jittered" version of its input coordinates. That is, the X, Y, and Z
coordinates each have a random displacement added to its value. For each coordinate you can
specify the amplitude of the random displacement, and the length scale over which that
displacement varies.
