TYPE: COP
TITLE: RotoSpline COP

This COP generates free form bezier or polygonal shapes. Adding and modifying
points is done completely interactively. Each point is animatable.

To create a rotospline, follow the prompts on the message line at the bottom of
the Houdini window. Also see the Rotospline Operation help in the toolbox.

Middle click on the dialog '?' help for more generator help.

Parameters:
Spline
    Spline Type     - Select Bezier or Polygon rotosplines.
    Fit Tolerance   - The tolerance applied to the bezier spline fit when
		      the rotospline is first created. It has no effect
		      once the spline is created.
    Level of Detail - The level of detail used when converting bezier
		      rotosplines to polygons before rendering.
    Fill            - The type of spline rendered.
	Closed  - A solid filled spline.
	Hollow  - An outlined closed spline.
	Open    - An open sline.

    Fill Outside    - If on, the 'outside' region is filled instead of the
		      interior (for hollow and open splines, the outside
		      region is the region not included by the line 
		      thickness).
    Thickness       - For Hollow and Open splines, the thickness of the
		      lines to use, in UV space. 
    Color           - The color to render the spline with.

Transform
    Overview - A 2D animated transform can be applied to the spline.  All
               units are in UV space.

Image & Sequence
    Overview - See extra help (Middle click on the dialog '?' help).

Local Variables:
    L   - Sequence length
    S   - Start of sequence
    E   - End of sequence
    IL  - Input sequence length
    SR  - Sequence frame rate
    NP  - Number of planes in sequence
    W,H - Width and height of image
    I   - Image index (0 at start frame)
    IT  - Image time (0 at start frame)
    AI  - Current plane array index
    PI  - Current plane index
    PC  - Num of channels in current plane
