document: Wavelet-based level-of-detail representation of 3D objects In this paper , we propose a 3D object LOD -LRB- Level of Detail -RRB- modeling system that constructs a mesh from range images and generates the mesh of various LOD using the wavelet transform . In the initial mesh generation , we use the marching cube algorithm . We modify the original algorithm to apply it to construct the mesh from multiple range images efficiently . To get the base mesh we use the decimation algorithm which simplifies a mesh with preserving the topology . Finally , when reconstructing new mesh which is similar to initial mesh we calculate the wavelet coefficients by using the wavelet transform . We solve the critical problem of wavelet-based methods - the surface crease problem - by using the mesh simplification as the base mesh generation method
