First, the boundaries of all the polygons to be stitched are found. An edge is a boundary edge if it is shared by no other polygon. The uniqueness of edges is determined by point numbers, and not by spatial positioning. Each boundary is then split at each "corner" into a number of pieces. A list of corner points can be manually specified, or any point at which the boundary changes direction by a certain amount can be flagged as a corner.
Finally, any two boundary pieces that are within the tolerance of each other are stitched together. This is performed by snapping the points of the high detail edge to those of the low detail edge.
Polygons to Stitch
The polygons to consider for stitching.
A list of point numbers that are to be considered breaks in the boundary edges.
Max Dist to Stitch
The maximum distance which two edges can be from each other and still be stitched together
When several points along ONE edge are snapped to the same position, consolidate them into a single point.
Automatically Find Corners
Whenever an edge changes direction at a point more than the specified angle, mark that point as a corner.
The maximum angle a boundary can change at a point before it becomes a corner.
This example demonstrates how the Polystitch SOP can stitch together or refine seams between polygonal surfaces with incongruent U and V divisions. This is useful for smoothing and eliminating cracks at seams.
