WebRay tracing [C++ & SDL2] - Episode 3 - Ray - Sphere IntersectionsWelcome to my new series on building a ray tracer from scratch in C++ with the SDL2 library!... Webp = t d + p 0. Plugging the ray equation into the sphere equation, we get. (t d + p 0 - p c) . (t d + p 0 - p c) - r 2 = 0. To solve, we'll need to get this into a t 2 + b t + c = 0 form to apply the quadratic formula to find the two solutions t = (-b +/- sqrt (b 2 - 4 a c)) / (2 a). Getting it into that form is a simple application of the ...
