hi The wrml i have is 3d model of cave, i created ascii file and i imported it in to grass (but only points), but i found a way to import this in to grass. First, import to blender and export to .dxf and then import .dxf in to grass (v.in.dxf). best mt

The only node type which has any real relation to GIS is the ElevationGrid type. This is what v.out.vrml generates. If you have a VRML file which is essentially a DEM which has been converted to an ElevationGrid, I suggest extracting the actual coordinate data using a text editor (or sed) then importing it with r.in.ascii. A VRML importer would require a fair amount of effort (it would need a full VRML parser just to extract ElevationGrid nodes), and I'm doubtful of its utility, given that any suitable VRML files would almost invariably have been generated from some other format, and the original data would probably be far more amenable to importation (i.e. GRASS probably already supports the format, and may be able to obtain georeferencing information from it). -- Glynn Clements <[EMAIL PROTECTED]>
