More 3D virtual rocks

The rocks in the image above are all virtual 3d models and are a selection of over 60 models available for download from the Intresto collection on Google’s 3dwarehouse (http://sketchup.google.com/3dwarehouse).

All the models were derived from real rocks so they have a natural look even when scaled to the size of a small stone or large boulder. The models were generated from a 3D laser scanner or from the point cloud derived from the Photosynth photogrammetry application. The models were processed as triangular meshes using MeshLab and then textures applied using Sketchup.

The models can be imported for free directly into Sketchup, used in your landscaping or hardscaping projects or exported as a Collada dae file then imported into Meshlab. From MeshLab they can be saved in a range of 3D formats such as VRML, obj, ply or stl then imported into CAD or 3D animation, graphics and rendering applications such as Blender. Have fun.
