Blender 2.5: Modeling terrains for architecture with Surface Sketch
There are a lot of ways to create terrains with Blender to use for architectural visualization. The technique to model a terrain will mostly depend on the reference that we have to create the terrain. One of the tools of Blender that can really help with the modeling of terrains is Surface Sketch. With this tool, we can import an image with the contour lines of the terrain and draw the lines to create the terrain. This morning I found a great tutorial that shows how to use Blender and Surface Sketch to create terrains for architectural visualization. Besides the modeling process with Surface Sketch, the author of the tutorial also shows how to create terrains using the bridge add-on for Blender, which was showed here a few days ago.
If you never had the opportunity to create terrains in Blender, I strongly recommend you to check out this tutorial!
