polySplit

Go to: Related nodes. Attributes.

Split faces and edges of a polygonal object. New vertices can be inserted along existing edges or placed as free points within existing faces. First and last new points must lie on existing edges.

Long name (short name)	Type	Default	Flags
vertices (v)	float3
Array (multi-attribute) of new free vertices (used to create a new point in a face). The order of the array corresponds to the order of the free points, but is not the same size and does not line up with the desc array (it only contains entries for free points).
vtxx (vx) distance (float) 0.0cm New vertex x coord
vtxy (vy) distance (float) 0.0cm New vertex y coord
vtxz (vz) distance (float) 0.0cm New vertex z coord
edge (e)	float	0.0
Array (multi-attribute) of edge distance ratios used to create new points on existing edges. Range of edge values is [0.0, 1.0]. A value of 0 puts the new point at the start of the edge, 1 specifies the new point should go at the endpoint. This array has the same size as the desc array. A free point index in desc will correspond with a -1.0 edge value for that index.
desc (d)	integer	0
Array (multi-attribute) of descriptors indicating whether the new point to be inserted should be placed on an existing edge or inside a face (as a free point). If a free point, the desc value for that index will be the face number. If the new point is to be on an existing edge, the desc value will be the edge number bitwise ANDed with either 0x40000000 for a hole border edge or 0x80000000 otherwise.
subdivision (s)	integer	1
Edge subdivision. New edges for which both vertices lie on existing edges will have this many subdivisions. New edges involving free points are not subdivided.
smoothingAngle (sma)	angle (double)	0.0deg
Angle below which new edges will be smoothed
maya70 (m70)	bool	true
Enable Maya 7.0 behaviour. This attribute is not meant to be modified through command line.
splitPoints (sps)	compound	n/a
Each entry is a set of connected split points.
splitPoint (sp) compound n/a contains a face id, triangle within the face, and the barycentric coordinates within the triangle of a new vertex position. face (f) integer 0 face id of a split point triangle (t) integer 0 which triangle within the face baryCoord (bc) double3 barycentric coordinate within the triangle of the point to be split baryCoord1 (bc1) distance (double) 0.0cm First bary coord baryCoord2 (bc2) distance (double) 0.0cm Second bary coord baryCoord3 (bc3) distance (double) 0.0cm Third bary coord
detachEdges (de)	bool	false
If true, and the split has been done using the splitPoint attribute, then a detach edge operation will be run on the resulting new edges.
clean2Verts (c2v)	bool	false
If true, the valence two vertices along the cut line will be deleted after the operation completes.
insertWithEdgeFlow (ief)	bool	false
True to enable edge flow. Otherwise, the edge flow is disabled.
adjustEdgeFlow (aef)	float	1.0f
The weight value of the edge vertices to be positioned.
