Here Manu explains one of his all time favourite setups: Dual Surfaces. By calculating the dual graph to the initial delaunay mesh, the triangle mesh that is, we end up with a very interesting voronoi-style surface topology. By splitting the mesh based on curvature, we then use this structure to come up with organic forms that remind of sea-creatures or reptile skin. Try this quick and easy effect that produces stunning results. Download project file: The render uses the sIBL HDR file “Old Industrial Hall“ that you can get here:
