pyOBJExplorer

Explore 3D visualization of Wavefront OBJ models with pyOBJParser, a showcase of how to integrate VPython and pyOBJParser. pyOBJExplorer offers an intuitive and straightforward solution, allowing users to delve into the intricate details of textures, materials, and geometries within OBJ files.

VPython (Visual Python)

VPython is a lightweight and simple Python library for creating interactive 3D visualizations and simulations, often used in education to teach concepts like physics and computer science. Testing Wavefront OBJ files larger than 10 MB for simulation is not recommended.

Following files is included

• Explorer.py The main file to run. It can also be executed from the command line with a specified OBJ file.
• WavefrontOBJ.py source: pyOBJParser
• WavefrontMTL.py source: pyOBJParser
• Triangulate.py source: pyTriangulate

Dependencies

• os
• sys
• numpy
• vpython
• atexit

Install vpython

pip install vpython

Usage

From the command line, simply enter 'explorer.py' followed by the file name.
Please ensure to close the browser upon completion to restore command line control.

python Explorer.py .\objFiles\rubikcube.obj

Rubik's cube with standard color

python Explorer.py -w .\objFiles\rubikcube.obj

Rubik's cube with wireframe

python Explorer.py -b .\objFiles\drill.obj

Drill with texture and axis align bounding box
