gewebe

a collection of tools, methods and techniques for working with meshes in Processing.

anatomy of a mesh

dependencies + libraries

• Processing
• Cycles a physically based renderer included in the Blender project
• Sunflow an open source rendering system for photo-realistic image synthesis written in Java ( v0.07.3 )
• Java 3D™ a scene graph-based 3D API for Java ( v1.5.2 )
• Computational Geometry Algorithms Library (CGAL) ( v5.0.2 )

known limitations and bugs

• CGAL binding only works on macOS
• Cycles standalone renderer is currently only compiled + distributed for macOS + windows ( but not tested )

resources

• Bandai Namco Research Motiondataset -- "This repository provides motion datasets collected by Bandai Namco Research Inc." motion data can be used with the BVH importer.

exporting model from 3D application to use in processing

• create shapes in 3D application
• convert model to mesh and to triangles
• export model as *.obj ( sometimes also called WaveFront )
• check file in text editor
  • file should only contain one line with group ( g ). additional groups will be ignored.
  • lines describing faces ( f ) should only contain 3 blocks of numbers. e.g f 1 2 3 or with textures f 1/4 2/5 3/6
• put file in data folder of processing sketch
• load file in processing sketch as string array. e.g String[] md = loadStrings("donut.obj");
• create mesh from model loader. e.g Mesh m = ModelLoaderOBJ.parseModelData(md).mesh();
