PyEngine3D is open source opengl 3d engine project wirtten in python.

Welcome to PyEngine3D

• An open source Python 3D engine using the pyopengl API that uses pygame and pyglet as the game backend.
• Homepage : https://pyengine3d.blogspot.com
• Documents : https://pyengine3d.readthedocs.io

Requirements

• OpenGL 4.3 ( Shading language 430 )
• numpy
• pillow
• pyglet or pygame
• PyOpenGL
• PyOpenGL-accelerate ( optional )
• Windows, Linux, Mac(not tested)

How to install PyEngine3D

  git clone https://github.com/ubuntunux/PyEngine3D
  cd PyEngine3D
  pip install -r requirements.txt
  python main.py

ImportError: DLL load failed

Solution1)
conda install -c anaconda pillow

Solution2)
conda install --channel conda-forge pillow=5

Solution3)
conda remove pillow
pip install pillow
