A GPU-accelerated implementation of Peter Shirley's "Ray Tracing in One Weekend" using Python, CUDA, and Numba.

Feb 1, 2023 · Ray-tracing is a method for turning information about 3D objects into a 2D image. It’s at the heart of bleeding-edge, photorealistic 3D graphics, and is a key development area for graphics card...

After a bit of Vector algebra brush-up I learnt about how to represent a sphere in a vector form and then it was pretty straightforward. Check if the ray is hitting the sphere: This is done by solving the quadratic dot(p(t) - C, p(t) - C) = R*R; All we had to check was to see if the discriminant was positive to confirm that there is a solution

A Python-based ray tracing engine that renders 3D scenes with realistic lighting, shadows, and reflections. Supports spheres, planes, and cubes with customizable materials and lighting.

Intersecting a ray with a sphere is the simplest form of a ray-geometry intersection test, which is why many ray tracers showcase images of spheres. Its simplicity also lends to its speed. However, to ensure it works reliably, there are always a …

Jul 20, 2013 · Very simple ray tracing engine in (almost) pure Python. Depends on NumPy and Matplotlib. Diffuse and specular lighting, simple shadows, reflections, no refraction. Purely sequential algorithm, slow execution. - raytracing.py

Oct 5, 2014 · In this post I will show how to use VTK to trace rays emanating from the cell-centers of a source mesh, intersecting with another target mesh, and then show you how to cast subsequent rays bouncing off the target adhering to physics laws.

Instantly share code, notes, and snippets. 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):

So please do type in the code, but you can find the finished source for each book in the RayTracing project on GitHub. A note on the implementing code for these books — our philosophy for the included code prioritizes the following goals: The code should implement the concepts covered in the books. We use C++, but as simple as possible.

Jun 2, 2021 · In this post I will explain the basics of ray tracing and show how you can implement a very simple program to render scenes containing spheres, lights and shadows using this algorithm. We will use Python, even though it isn’t the best language for this kind of application, it will serve us very well for learning purposes.
