CPU powered raytracer written in C++
The pre-compiled binaries won't work on anything else
./raytracer [file.scene]The program will create a output.ppm file.
To view the produced image, you can do so using the included viewer
./PPM_viewer [file.ppm]
Ladies and Gentlemen, behold the sphere!
This was supposed to be a raycasted sphere, well... Something definitely didn't go as planed.
As you can see by the shadow below the sphere, this is already raytraced and illuminated by the sky.
Here I had to implement a proper material class that handles rays differently depending on the choosen material.
Spheres are cool, but what's cooler is being able to render any type of surface, so here's planes. I wish I had the time to implement triangles, This would've allowed me to support obj files and my raytracer would've been able to render actual 3D meshes.
This scene introduces 2 new main things. First of all, an actual light material that illuminates its surroundings, it was limited to light from the sky before that. And also boxes, which is a simple mix of 6 planes. You can see some very nice penumbra shadows in the scene, as well as some subtle indirect lighting hitting the roof.
This image doesn't really introduces anything new, but I just think it looks cool and it deserves to be showcased :)
