Simple implementation of path tracing, based on the Ray Tracing in One Weekend series. Not good -- just an exercise for different ways to speed up a program.
- Very simple raytracing
- No configuration or command line options, you can only write a new function or change existing variables in the code and recompile the whole thing
- Multithreaded ray tracing with either POSIX threads or Windows threads
- Almost definitely way slower than it could/should be
I know that this build works using clang to compile, as used in the build
scripts. If you want to use a different compiler, gcc might also work.
Currently, I don't think msvc will work because I'm trying out using a
compiler extension for locked adds.
There are no arguments. Just run
./build.sh
on *nix or
.\build.bat
on Windows.
This will build the program and immediately render a 384 x 216 bitmap. If you
want to change the scene or render a larger image you'll have to modify
yellow.cpp. Note that you'll need clang in order to compile using these
scripts. I'm also using a __sync_fetch_and_add compiler extension.
