You can do so by navigating to Layer -> Add Raster Layer -> Select Once you have GRASS installed start by adding your raster layer.

Make sure it is checked in your Manage and Install Plugins list! In order to install the GRASS plugin (if you already have QGIS installed), just navigate to Plugins -> Manage and Install Plugins -> Get More and install GRASS. I have found that NVIZ (which is a part of the GRASS package) is a useful tool for visualizing DEM data as a 3D model. So, really, your best bet if you have a GeoTiff, ASC or just about any other height data raster is to write a little script to iterate over the raster as there is no ready-made plugin for most use-cases, unless you can export your DTM to DXF, VRML or OBJ. IMG importer in Blender but GDAL can only read PDS IMG files (not to be confused with Erdas IMG files which are different).

There is an add-on for XYZ data but it is non-standard and aimed mainly at molecular data, though perhaps you could bend it to your will. ArcScene and NVIZ) though this route is maybe necessarily strictly free.
The only thing you need to be careful of is that the version of GDAL you have matches the version of Python in the Blender release you are using. Therefore, I use Python in Blender and import the GDAL libraries and construct a Blender-native mesh directly from the GIS data. As a result, STL files contain no scale information, and the units are arbitrary.Blender has a Python API. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. Binary files are more common since they are more compact.Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing.

Many other software packages support this file format. STL is a file format native to the stereolithography CAD software created by 3D Systems. The platform is used worldwide in commercial applications, as well as in research and development. VTK is part of Kitware's collection of supported platforms for software development. It comes with state-of-the-art tools for 3D rendering, a suite of widgets for 3D interaction, and extensive 2D plotting capability. The Visualization Toolkit (VTK) is open-source software for manipulating and displaying scientific data.
