Python Ray Tracing

It's a simple ray tracing engine on python designed for rendering scenes. The code is written keeping as much readability as possible.

Render example

Installation and Launch

The project supports python 3.10.0 and higher.

Just clone or download this repo.

Install dependencies using the command pip install -r requirements.txt.

Code example of a simple scene:

import numpy as np
import matplotlib.pyplot as plt

from RTEngine import RayTracingEngine
from RTEngine import Material
from RTEngine.objects import Sphere, Cube
from RTEngine.lights import Light

if __name__ == "__main__":
    scale = 3

    camera_pos = np.array([0, 0, -3])

    lights = [
        Light([0, 2, 0.3]),
    ]

    objects = [
        Sphere(np.array([0.5, 0, 0.5]), 0.3, Material([0.9, 0.6, 0.6], 0)),
        Sphere(np.array([-0.5, 0, 0.5]), 0.3, Material([0.6, 0.6, 0.9], 0.7)),
        Cube(np.array([0, -1000, 0]), 1000 - 0.3, Material([0.5, 0.5, 0.5], 0.3))
    ]

    rte = RayTracingEngine(300 * scale, 200 * scale, 6, camera_pos, objects, lights,
                           sky_color=np.array([0.3, 0.6, 1.0]) / 2)

    plt.imsave('image.png', rte.render(sampling=8, gamma=0.7))
