TYPE: SOP
TITLE: PolyBevel SOP

PolyBevel can be used for beveling points and edges. In the most simple case of zero repetition, it replaces points and edges with faces. This is a useful tool for removing sharp edges and points and creating some basic shapes such as 
tetrahedons and soccerballs from boxes. It can be used to increase 
detail in facial features by bevelling edge loops around eyes and mouths.

Parameters:

    Group		 - The edges or points to bevel.
    Bevel Type		 - At zero repetition, all four bevel types result in
			    identical outputs (that is, single surfaces are 
			    formed in place selected points and edges). The 
			    difference between the bevel types is characterized
			    by the way each adds detail to the resulting 
			    bevelled faces with increasing repetition values. 
			    There are four bevel types:
	Flat - The bevel surfaces remain flat, but are divided into symmetric 
		sets of new geometry.
	Low Density Round - Edges are rounded with additional geometry added
		in place of flat bevel surfaces with curvatures that
		approximate the original edges. Faces that replaced corners
		in edge and point bevelling are substituted by minimal 
		additional geometry to maintain a sense of curvature around
		the original corner. The low density round is often a better 
		option than the high density round in the cases of bevelling 
		irregular geometry and large sets of geometry because it is 
		unlikely to produce unexpected or overlapping geometry 
		in the corner areas.
	High Density Round - Edges in the high density round bevel are treated 
		in the same way as in the low density round bevel. However,
		faces that replaced corners in edge and point bevelling are
		substituted by multiple quad patches between adjacent boundary 
		edges. It is important to note that there is not necessarily 
		continuity between patches that share a common boundary edge 
		and that this lack of continuity becomes more apparent 
		at higher repetitions. It is recommended that the subdivide 
		sop be used for further smoothness. In the case of point 
		bevelling, the high density round may not be the best choice 
		for obtaining a rounded corner.	One alternative is to corner 
		bevel the point and smooth the resulting geometry from the 
		corner bevel using the divide sop.
	Corner - This bevel type maintains the shape of the original geometry
		while additional geometry are introduced. 
			
    Relative Inset	 - Inset is interpreted as a ratio of the distance from
			    a primitive's vertices to its center. This type
			    of inset is bounded. It is the best choice when 
			    bevelling large sets of geometry, facial features, 
			    and in cases where very different sizes of 
			    primitives are involved. 	    	/relinset
    Absolute Inset	 - Inset is interpreted as an absolute length from 
			    either a vertex along an corresponding edge 
			    or from an edge along its perpendicular. This type 
			    of inset is generally not bounded. It is useful 
			    when bevelling symmetrical geometry, small sets of 
			    geometry consisting of primitives with similar
			    sizes, and in cases where the desired inset is
			    explicitly known.			/absinset
    Repetitions		 - Repetitions is a measure of the quantity
			    of additional geometry introduced. It correlates
			    to twice the number of geometry added in place of
			    an edge and to twice the number of segments 
			    each edge of the new face created in place 
			    of a point is divided into.		/repetitions
    Recompute Point Normals - Re-evaluates point normals if they
			    exist.  If this is not set, the point
			    normals will be interpolated in the same
			    manner as the points.
