I have difficulty in rasterizing 3 dimensional dxf (single building) to mask netCDF using GRASS, Blender, or Qgis.
I want the mask netCDF to have value 1 in interior of the building and zero value out of the building. But the dxf file has only geometric information. How can I get mask 3d ? Once I could get a mask 3d, I can convert it to netcdf using
I think I should assign 1 value to the volume covering surfaces, first. I know I can assign some value to vertexes. If so, how can I assign 1 value to the volume of interior building?
v.to.rast3in GRASS (Converts a vector map (only points) into a 3D raster map) enter link description here. So GRASS can convert vector points to 3D raster map (voxelization). But I need to convert a volume (surrounded by faces) into a 3D raster map.
