Key techniques on terrain rendering based on wavelet translation
|
Abstract:
This paper showed how to select suitable wavelet basis for terrain rendering according to the characteristic of DEM data and how to filter wavelet coefficients according to viewpoint and complexity of the terrain block to implement progressive reconstruction. Then it analyzed several boundary problems caused by block wavelet transform and gave the solution. Finally, it proposed an acceleration algorithm for wavelet translation based on GPU to improve rendering efficiency.
