General Module Function

triangulate_polygons converts a closed polyline into a triangulated surface. This surface can be extruded or used by the area_cut module to perform areal subsetting of 3D models.

Polylines with WIDTH in AutoCAD DWG files are converted by Read_CAD into triangle strips of the specified width.  As you zoom in on polylines with width, the apparent width will change, whereas the apparent width of lines DOES NOT change.  However, once they are triangles, they DO NOT define a closed area and therefore would not work with triangulate_polygons.

Module Input Ports

triangulate_polygons has only one input ports which is one or more closed polylines that will be converted to triangles. triangulate_polygons does not use the convex hull of a closed polyline, it honors the full complexity.

Module Output Ports

The triangulate_polygons module has two output ports. The first output port (closest to the left) outputs an EVS field containing the triangulated surface. The second port outputs a renderable version which can connect directly to the Viewer.

Module Control Panel

The control panel has only one parameter which is the tolerance for closing polylines.
