I want to create a fly-through in GRASS GIS 3D. The problem: throughout the "flight" the rendering is at low visual resolution, while it is set a high resolution. Is there a way to render a flight sequence at high resolution (1)?

    Did you set under "Data" tab the "Fine resolution" to a low number (yes, that's a bit counter-intuitive)? See also grass.osgeo.org/grass72/manuals/wxGUI.nviz.html#data-properties – markusN Nov 26 '17 at 13:43
  • Yes. Static rendering is fine, just when I switch to fly mode it gets crude. One work-around is Meshlab/Blender, but then I need to convert all to vector data and I want to avoid that. The data set is all raster. – Peter Nov 27 '17 at 7:02

    Try to set "Coarse resolution" to 1 as well. – Anna Nov 27 '17 at 18:34
  • Anna - thank you. That works. Makes sense, as GRASS renders "coarse" initially. – Peter Nov 28 '17 at 6:12
