A brief post not related to Surface modeling but still hopefully useful...Last week-end I was testing a first version of the X3D converter to be added to CAD Exchanger. X3D stands for eXtensible 3D format (ISO19975) which could be seen as a successor of VRML format. Check http://www.web3d.org for more details.The persistent representation uses XML as a file format, and I use Open...
(continued...)PlatingThis is one of the advanced techniques of surface modeling that Open CASCADE offers. Other names for it are hole filling, or constrained filling. ACIS calls it covering.It involves creation of a surface that meets several constraints:- point constraints – the surface must pass through given points;- point constraints and tangency, and (optionally) curvature – the same as above + extra Gn requirements...
