I have a high resolution landscape which was generated through Metashape using drone footage of a localized area. This is a great model but it includes all sorts of detail such as trees, which I would like to remove so that I have a relatively accurate map of only the landscape.
I have been able to produce a nice topo-map using depth data (of course this also shows high density tree locations). Can anyone suggest a good way to reduce the density of the mesh while retaining a close contour of the landscape itself?
I’ve not had much luck with the standard decimation tools, but perhaps that’s a matter of user ignorance. I’ve also tried shrink wrapping a grid as well as cloth simulation, dropping the cloth grid over the ladscape with the thought that it might be easier to smooth out the trees once I have a uniform mesh but I can’t seem to find the right technique. Is this really just a matter of brute force on a very high density mesh?
I would also need to insure that the orthographic UVs are able to transfer properly in order to prevent distortion from the map generated through Metasape.
