How to compile

• mkdir build
• cd build
• cmake ..

How to use

You must be in the project root dir, leave the build folder if you're still in it.

Scene files are located in the resources directory. Take a look at resources/light_scene.json if you're interested in how to make a scene for yourself. (Hint: the available object types are sphere cube_box menger).

Let's render our basic raytracer scene. ./build/isim ./resources/light_scene.json ./build/output_light.png

If you want to render our sponge fractal. ./build/isim ./resources/result_scene_1.json ./build/output_sponge.png

How to watch results ?

Open the png file you generated.

What about animated results ?

Unfortunately, we didn't have time to code camera movement in the json file. Therefore it has to be done in code, and repeatedly call the function snapshot in main.cpp. Of course this is less than ideal, and we don't recommend that you bother doing this.
