Bas-relief generation algorithm based on laplace operator decomposition of 3D model

Bas-relief generation algorithm to compress the depth of a Three Dimensional(3D) model in view direction was studied.Taking the idea of mesh fairing by Laplace operator,a 3D triangular mesh model was decomposed into parts with different frequency:base mesh,Laplace operator and higher degree Laplace operator.A bas-relief generation algorithm was proposed by setting different compression strategy for the decomposed parts.There was no necessity in conducting re-sampling for the model and solving large sparse linear function.The generated Bas-relief models were machined in different materials.Experiments demonstrated that the bas-relief had fine details with better visual effect.
