Real-time ASCII 3D rendering engine

Project description


RendASCII is a real-time, z-buffering based 3D rendering engine written from scratch in and for Python 3. Unlike traditional real-time rendering engines, RendASCII renders frames as printable strings using ASCII characters for pixels. RendASCII is open source under the MIT license.

  • No external dependencies; uses just the Python standard library.
  • Multiprocess based rendering.
  • Optional Cython based accelerator extension modules.
  • Load and render 3D models from Wavefront object and material files (*.obj and *.mtl, respectively).
  • Load and render 2D sprites from ASCII based Portable PixMap files (*.ppm).
  • Render the same or different scene(s) using multiple virtual cameras.
  • ASCII overlays for displaying fixed graphics and/or information.
  • Map sprite and material colors to ASCII characters using JSON colormaps.
  • Transform models, sprites, and virtual cameras using arbitrary homogeneous transformation matrices.
  • Utility for easily constructing complex transformation matrices with scaling, translations, and rotations.
  • Utility for managing frame-rate and calculating delta time.


Using Pip

# pip3 install rendascii - download and install pure Python distribution.

# pip3 install --no-binary rendascii rendascii - download source distribution, build accelerator extension modules, and install resulting binary distribution.


$ git clone - clone repository source.

$ cd rendascii - change working directory to cloned source.

# python3 -m setup install - build accelerator extension modules and install resulting binary distribution.

# PURE_PY_DIST=true python3 -m setup install - build and install pure Python distribution.
