Tao creates geometry along paths, and gives you several options for that path. The Path Generator group creates a path for you.
The Generate Path checkbox creates a path for you to use in one of three shapes: circle, line, or fractal. This option is on by default, so if you would like to use another method to create a path (such as with a mask or a path from a light), you may want to turn this option off.
Shape pop-up menu:
The Size property controls the size of the path, and therefore the overall size of the structure when the Shape pop-up menu is set to either Circle or Fractal. This value is relative to the height of the composition. With Size set to 50 for example, Tao will be 50% of the comp height. Note that fractal displacement allows geometry to go beyond this value, but the bulk of the geometry will still exist in that range.
NOTE: This is not to be confused with the Size parameter in the Segment group, which controls the size of the pieces of geometry along the path.
The Center value controls the center of the path when the Shape pop-up menu is set to either Circle or Fractal.
Rotate X, Y, Z Rotates the mesh around the X, Y and Z axis. This does a 3D rotation that is processed before the transformations in the Repeater and World Transform groups, so these properties only rotate the original path, not the whole world.
When the Shape pop-up menu is set to Line, the path becomes a line drawn from Line Point 1 to Line Point 2, both of which have their own X, Y, and Z position coordinates. When the Shape pop-up menu is set to Fractal, the displaced path it creates can be adjusted by the following fractal properties.
Gridify will constrain path deformations to happen only along the X, Y, and Z axis, creating a grid-like structure.
Enable tapered edges by turning on the Taper Size checkbox. Selecting this options also enables other parameters for adjusting the taper.
Start Path specifies (in percentage) where the geometry begins along the path.
End Path specifies (in percentage) where the geometry ends along the path.
Start Taper determines (in percentage) where the starting taper ends, and the geometry is its normal size.
End Taper determines (in percentage) where the ending taper begins.
