Whereas the latter is made in multi-paneled mold segments that join together, thus permitting the development of more sophisticated surface modeling, texture and design.
The high end discipline in surface modeling matches the quality level of Class A. This modeling effort needs advanced tools and different workflows as concept modeling.
Another type of modeling technique is 'surfacing' (Freeform surface modeling).
Rodin's talent for surface modeling allowed him to let every part of the body speak for the whole.
A two-dimensional contour map created from the surface modeling of rainfall point measurements may be overlaid and analyzed with any other map in a GIS covering the same area.
The upper part of the tower was furnished with battlements and a pattern of surface modeling of the brickwork, several nice ring dog tooth courses running below the battlements.
Implicit surface modeling - an older subfield which examines the use of algebraic surfaces, constructive solid geometry, etc., for surface representation.
Freeform surface modeling is often combined with solids to allow the designer to create products that fit the human form and visual requirements as well as they interface with the machine.
Freeform surfaces (usually NURBS) allow more complex shapes to be represented via freeform surface modeling.
Nor Arneson, whose stoneware "Abstract Vessel" (1957) is a surprisingly unrepresentational (for him) essay in tortuous surface modeling, almost like a sculpture by de Kooning.
