A hobby portable raytracer in C++.
- Written in portable C++98, compatible with GCC, DJGPP, and Open Watcom v2 (Linux and MS-DOS targets)
- 3D scenes are described in a simple text format
- Outputs rendered images as PNG or JPEG
- Multi-threaded rendering on platforms with OpenMP support
Install the required tools if not already present:
mikraytrace > apt-get install build-essential cmake
Some external libraries are used for image processing (toojpeg98 and lodepng); these are vendored directly.
You will also need example textures. I created a texture pack
based on free textures from OpenGameArt.org. Create a textures directory and
unpack them there.
The project is built with CMake. Use any of the attached build scripts, like so:
mikraytrace > ./build-gcc-linux.sh
The MS-DOS build scripts have hardcoded compiler paths; set the WATCOM and DJGPP
environment variables to override this.
Render a scene by passing one or more scene files to mrtp_cli:
mikraytrace > ./build-gcc/mrtp_cli bluemol.txt
