A simple Python raytracer that supports spheres with configurable "material" properties (base color and a bunch of
light coefficients). To generate a raytraced image of the pre-defined scene, run: python raytracer.py and open
image.ppm with a PPM-compatible viewer (eog works fine on Linux):
I found the following resources extremely helpful:
| import numpy as np | |
| import matplotlib.pyplot as plt | |
| def normalize(vector): | |
| return vector / np.linalg.norm(vector) | |
| def reflected(vector, axis): | |
| return vector - 2 * np.dot(vector, axis) * axis | |
| def sphere_intersect(center, radius, ray_origin, ray_direction): |
