Image Description, by Bruno Levy



This image shows our newest results for the LSCM parameterization method. More details are available from http://www.loria.fr/~levy

LSCM (Least Squares Conformal Maps) makes it possible to create an atlas, i.e. a representation of an object very usefull for texture mapping, level of details with normal maps, ... This latter application has been previously shown at Flipcode by Charles Bloom, see his page here.

To construct an atlas, the model is first subdivided into pieces, which are flattened. The flattened pieces are then grouped in (u,v) texture space (lower left image). The lower right image shows how a regular grid is mapped from texture space to the object.

This parameterization has been constructed thanks to a multiresolution version of LSCM, combined with an automatic segmentation algorithm.
