Hi,
Wondering if someone can point me in the right direction. I have grass 7. I am using NVIZ to display a dem with raster and vector overlays. Looks fantastic. I now would like to export this model (with colours and light settings etc) to VTK, ultimately so I can convert it to dae file so I can load several of them in Google earth as DEM's stacked on top of each other with surface and vectors. I can find lots of documentation / help with parameters and settings but am not having much luck on actually exporting the models. I have searched video tutorials but haven't found anything there either. I have a simple need - am finding it very complex with no success. I think I am stuck at converting 2D rasters to 3D rasters first. I also tried generating all the parameters to create a 3D raster. This gave me a nice script based on the 3d display of DEM, overlay, vectors, colours, vertical exaggeration etc. I tried to paste this from the GUI to the NVIZ 3d dialog for generating a ppm file but couldn't paste it. I had to use the dialog to build the script which is displayed at the bottom of the dialog but it cannot be copied or pasted. This process created a ppm file but was only 1k with no 3d model to be found. I would be grateful if someone could point me in the right direction. Regards David
