Welcome to my Raytracer in one weekend (or two)

Thanks to Peter Shirley and his book Ray Tracing in one weekend for making this exercise so easy and enjoyable.

Compile & run

Assuming a file called raytrace.cpp containing scene description similar to the sample programs, use g++ -Wall -std=c++11 -o raytrace raytrace.cpp

All sample programs will take as argument the name of a file to write to, if no argument is given the program name is used. ./raytrace output_file

Then simply open the generated output_file.ppm with your image viewer of choice.

You can also build the "main" program with viewer using cmake. From the project root directory: mkdir build cd build cmake .. && make

And run bin/raytracer.

Samples

There are examples and tests that can be compiled and ran automatically using the bash scripts found in the respective folders. Note that on Windows you'll have to have nomacs installed and an alias set for the example script to be able to show the result. Otherwise you can simply open the resulting file manually.

All example programs can produce a PPM image, written to a file for which the name can be given as parameter. If no parameter is given, the name of the executable is used to generate the output file.
