A very fast and simple software renderer using only integers and fixed point math. PiSHi LE (PL) is a subset of the 3D software graphics library used in King's Crook.
PL3D-KC
PiSHi LE + FW LE Public Domain Source Release by EMMIR 2018-2022
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:
- Everything must be done in software, no explicit usage of hardware acceleration.
- No floating point types or literals, everything must be integer only.
- No 3rd party libraries, only C standard library and OS libraries for window, input, etc.
- No languages used besides C.
- No compiler specific features and no SIMD.
- 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!
