Automatic generation of 2.5D digital bas-relief from 3D model recently becomes a hot spot in relief design.This paper proposes the algorithm for semi-automatic generation of bas-relief from 3D triangle mesh,and compresses the 3D model through non-linear decreasing geometric energy in the frequency domain.In order to meet the image spectral analysis,the triangle mesh of original models is changed into range image by resampling.In the compression process,the low frequency energy is compressed through high pass filter tools and application of methods such as logarithmic compression function on edge of mesh models to achieve better results.Examples show that generating the bas-relief in frequency domain is feasible,and the model without rich details is used to produce the same better digital bas-relief.
