TYPE: CHOP
TITLE: Geometry CHOP

This CHOP reads point positions and point attributes from a SOP. Point 
information can be modified by CHOPs, and then stuffed back into geometry
using the Channel SOP.

There are no local variables.

Parameters
Geometry
    SOP             - Retrieves the geometry from the SOP pointed
		      to by this path.
    Group           - Fetch only the points within this point group.
		      If blank, all points are fetched.
    Method          - The geometry fetch method.
	Static   - Creates one channel for each attribute, and
		   all points use this channel (the first point
		   resides at index 0, the next at 1, and so on).
		   The length of the channels will be the number
		   of points fetched.
	Animated - Creates one channel per attribute per point.
		   The channels show the animation of each 
		   point's position/attribute values.
    Attribute Scope - A string list of attributes to fetch from the
		      SOP. The common attributes are:
        P     - point position (X, Y, Z) - 3 values
        Pw    - point weight - 1 value
        Cd    - point color (red, green, blue) - 3 values
        Alpha - point alpha - 1 value
        N     - point normal value (X, Y, Z) - 3 values
        uv    - point texture coordinates (U,V,W) - 3 values
    Rename Scope    - The names to use for the newly fetched 
		      attributes. There must be one name per attribute,
		      so an attribute scope of "P" should have a
		      rename scope with three names (like tx ty tz).
    Transform Object - If a transform object is specified, the point values
		      will be represented relative to that object's
		      origin and rotation. 
    Organize by Attribute - (Applies to 'Animated Method' only)
		      Will rebuild the fetched channels by the value of
		      this attribute.  A common example is the 'id' 
		      attribute found in particles.  A channel is built for
		      each unique id since the number of points may vary.
Channel
    Start/End       - The time range over which to fetch    /start /end
		      the geometry values when "Animated"
		      Method is selected.
    Sample Rate     - The sample rate to use for the        /rate
		      fetched channels.
    Extend Left     - The extend condition before the 
		      channel's beginning.
    Extend Right    - The extend condition after the 
		      channel's ending.
    Default Value   - The value of the default value        /defval
		      extend condition.
