In order to test whether a ray hits a transformed object, we need to describe the ray in the object's local coordinates. We transform the ray by the inverse of.

A tiny ray tracer, only useful for people who never written one themselves, but would like to. It lacks features, but provides a foundation to build your own, featureful ray tracer upon.
3. Parametric and Implicit Surfaces - A Minimal Ray-Tracer
The focus of this lesson is to explore how the property of being definable by an equation facilitates the calculation of ray-geometry intersection tests.
In the previous lesson, we learned how to generate primary rays. However, we have not yet produced an image because we have not learned how to calculate the intersection of these primary rays with any geometry. In this lesson, we will explore computing the ray-geometry intersection for simple shapes, such as spheres. Spheres are relatively straightforward to ray-trace, making them a common choice for those learning to program a ray tracer. Thus, this lesson will cover a somewhat eclectic mix of topics:

Aug 8, 2018 · We will be building a fully functional ray tracer, covering multiple rendering techniques, as well as learning all the theory behind them.
We investigate the basics of ray tracing and render some spheres.

Jul 8, 2021 · In this blog post, I want to show you how I did it for mine. The testing code is approximately 300 lines long. I try to break down each important part into ...
Every single time I want to consider myself done with the PSRayTracing project, I find myself running back to it for something. Recently I’d like to start contributing to another ray tracer that was also based on the same books, so I asked the main developer if he had any testing infrastructure up. Other than some sample files, He really didn't.

Ray tracing is a technique used for rendering scenes with 3d geometry. ... At this point, you will be able to test your raytracer implementation thus far and ...
8. A Minimal Ray-Tracer: Ray-Sphere Intersection - Scratchapixel
The geometric solution to the ray-sphere intersection test relies on simple math, mainly geometry, trigonometry, and the Pythagorean theorem.
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 few important subtleties to pay attention to.
