I'm a graphics programmer, an amateur physicist, and a sci-fi nerd. I teach computers how to make pretty pictures. I'm excited by beautiful, immersive, story-driven games and interactive fiction. I enjoy messing around with esoteric ideas. I like explaining things.

I currently work for NVIDIA DevTech. Previously, I worked for Sucker Punch Productions on the Infamous series of games for PS3 and PS4.

comment How to numerically solve a complex equation?
This is impossible to answer without being more specific. Numerical root-finding (which is what this is) is a huge topic.

@HaoYe That's a good point. Would you mind posting that as an answer?

comment Maximum number of vertices in intersection of triangle with box
@HaoYe By "0 vertices" I just mean that the intersection could be empty. No, I don't mean original vertices of the triangle and box, I just mean the corners of the polygon created by intersecting them.

comment Intersection between a cylinder and an axis-aligned bounding box
I think you could construct $P$ more simply as $P = 1 - \vec v \vec v^T$. The matrix $\vec v \vec v^T$ (the outer product of $\vec v$ with itself) maps a vector to its projection on $\vec v$, assuming that $\vec v$ is unit length. Then $1 - \vec v \vec v^T$ projects onto the plane perpendicular to $\vec v$.

comment Least square solution based on the pseudoinverse solved efficiently with singular value decomposition
You can start by reading the Wikipedia article on SVD. Calculating the Moore-Penrose pseudoinverse is the first thing listed in the applications section.
