PiSHi LE + FW LE Public Domain Source Release by EMMIR 2018-2022

alt text

PiSHi LE (PL) is a subset of the 3D graphics library used in King's Crook. FW LE is a subset of the windowing library used in King's Crook.

Just like King's Crook, this code follows the same restrictions:

  1. Everything must be done in software, no explicit usage of hardware acceleration.
  2. No floating point types or literals, everything must be integer only.
  3. No 3rd party libraries, only C standard library and OS libraries for window, input, etc.
  4. No languages used besides C.
  5. No compiler specific features and no SIMD.
  6. Single threaded.

================================================================ Feature List:

  • N-gon rendering (not limited to triangles)
  • Depth (Z) buffering
  • Flat polygon filling
  • Affine texture mapped polygon filling
  • Near plane clipping
  • Viewport clipping
  • Back face culling
  • Immediate mode interface
  • Matrix stack for transformations
  • Code to generate a box
  • King's Crook DMDL format importer

================================================================

Compiling for macOS/Linux:

  cd PL3D-KC

  cc -O3 -o pl *.c fw/*.c -lX11 -lXext

  ./pl

or use CMake for Linux, macOS or Windows -- tested with GCC, Clang, Intel oneAPI, Visual Studio, NVIDIA HPC SDK, AOCC, ...

cmake -B build
cmake --build build
build/main

macOS requires an X-server such as XQuartz running in the background. Prerequisites for macOS can be installed via Homebrew:

brew install libx11 xquartz

Don't forget to compile with max optimization!
