Loading Geometry into NetLogo3D

NetLogo3D is an Agent-Based Simulation which uses a three-dimensional raster as environment its agents. It has three different ways to represent geometry, (1.) as wireframe made out of vertices and edges, (2.) as solid faces or (3.) as voxel grid. Sadly, loading geometry is only supported for the second option, through a proprietary text format for which no converter exists. The other two options are completely left to the programmer. I find that this is a pity, and have therefore worked on loading geometry from a standard format (Wavefront .obj) and representing it as one of the three mentioned options. The description of the resulting model, available at [1], is the aim of this technical report.
