Started coding during a boring friday lecture in uni, finally finished on a rainy Saturday
Definition: A path tracer is a type of rendering program or algorithm that generates images by simulating the paths of light rays as they bounce around a scene, capturing realistic lighting, shadows, reflections, and refractions.
Why in Python: I dont know. I wanted to type less words and doze off in between the renders.
Resource: Ray Tracing in One Weekend (Part 1 and Part 2)
The heart of the pathtracer is the ray_color() function inside core.utils.
I've tried to write extensive comments in various places to explain in short.
I've implemented Sphere and Quadrilaterals till now, and three material types: Lambertian Diffuse, Metal and a
Light Emitting one.
Note
The first 2 photos are so noisy because I had kept sampling = 30, to reduce the rendering time.
Formatted with black.
Git clone, and run main.py. Tune parameters beforehand.
The image generated will be of .ppm format.
Note
Read this if you are having some trouble with understanding how the viewport works.
I don't want to bother myself by typing the same thing again, so just see my scribbles below:
