Volume-preserving FFD for programmable graphics hardware
2011
The Visual Computer
Preserved Fulltext
Several authors have addressed the problem of volume preserving FFD. ...
In this paper we take advantage from the multi-linear nature of the volume constraint in order to derive a simple, exact and explicit solution to the problem of volume preserving FFD. ...
In [21] it has been shown that FFD can be accelerated significantly using programmable graphics hardware, but without volume preservation. ...
