| Summary | 0028125: Modeling Algorithms - support of BRep shapes based on tessellated geometry | ||||
| Description | OCCT TopoDS model allows defining BRep shapes with edges and faces based on triangulated representation, without geometric curves and surfaces. This representation can be quite useful in some applications, especially when working with large models without a need to modify them. However, most of OCCT algorithms cannot handle such data. It can be reasonable to improve some OCCT algorithms to be able to deal with tessellated shapes. The first candidates are: - calculation of bounding boxes -- should be already available (BRepBndLib) - calculation of volume and surface properties (BRepGProp) - calculation of distances between objects (BRepExtrema) - calculation of HLR (HLRBRep_PolyAlgo)? This is meta-issue to provide this kind of functionality in OCCT. Issues for improvements of particular algorithms shall be created as children of this one. | ||||
