Ray and sphere intersection
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 ... WebJun 14, 2024 · esteban.egea April 25, 2024, 8:41am 5.
