Then the map image is draped over top of the 3D surface and rendered with realistic lighting. The software will generate a 3D surface by extruding parts of the image using DEM pixel values as the magnitude of extrusion. Blender can use rasterized elevation data in a similar way to GIS software such as ArcGIS and QGIS. The two images used to create the maps below can be downloaded Here.Ī 3D map can be created in Blender using two images: A map of the area of interest and a digital elevation model (DEM) that covers the area. Render a 3D map with realistic lighting.Create a 3D surface from elevation data in Blender.Modify GIS data so it is suitable for Blender.By the end of this article you will understand how to: This article is a brief introduction to using Blender to visualize GIS data for those with some GIS and raster manipulation experience. Blender is a versatile open source 3D creation suite that is able to render maps with realistic lighting and textures.
