Class that implements the data storage and functionality of a region as a connected area of triangles on the mesh surface that share common curvature properties. These triangles are situated on relatively contained and localized position on the mesh which are thus implemented as regions.

| void edu.tum.cs.vis.model.util.Region.addTriangleToRegion | ( | final Triangle | newTr | ) | [inline] |
Adds triangle to the list of triangles included in the region. The addition is performed only if the triangle was not previously inside the region. If the triangle was already in the region, this function does nothing.

| void edu.tum.cs.vis.model.util.Region.addTriangleToRegionBoundary | ( | final Triangle | newTr | ) | [inline] |
Checks if a triangle is at a region's boundary and if it is it adds it to the list and then removes any triangles from the list that are not longer at the boundary. If the triangle is not at the boundary, this function does nothing. The check is based on the neighbors of the triangle compared against the triangles already in the region.

| void edu.tum.cs.vis.model.util.Region.buildUpRegion | ( | ) | [inline] |
Builds the region starting from the initial triangle seed used to initialize the region. The growing algorithm makes sure to classify triangles with the same curvature properties in the same region without stepping over the edges identified as sharp edges. Thus the growing process is based on the neighboring relations among triangles and on their curvature information. Consequently, connected triangles on the mesh that share same curvature properties and are not separated by a sharp edge are brought together starting from the seed triangle of the region.
The region growing algorithm is based on the paper "A new CAD mesh segmentation method, based on curvature tensor analysis", Guillaume Lavoue, Florent Dupont, Atilla Baskurt, Computer-Aided Design 37 (2005), 975–987.
