vbo-convert

A few ways to convert Tangram VBOs to 3D file formats.

These scripts work with vertex buffer objects (VBOs) exported from Tangram. For an example of how to export these VBOs, see https://github.com/meetar/manhattan-project/blob/master/lib/batch_export.js

usage

python [scriptname] [infile] [outfile]

example usage

python vbo_to_ply.py tile_verts tile_faces.ply

filelist

• tile_verts - processed vertices extracted from a Tangram tile's VBO
• tile_verts_small - a trimmed version of tile_verts with only 1000 vertices
• vbo_to_obj.py - Wavefront OBJ format converter
• tile_verts.obj - sample output of above
• vbo_to_ply.py - Stanford Poly format converter - includes vertex color information
• tile_verts.ply - sample output of above
• tile_points.ply - example pointcloud for visualization
• tile_faces_base.stl - example of OBJ file converted to STL, with an extruded ground plane
• tile_faces_base.gcode - stl file sliced with Makerbot software – ready to print!
