 Apr 7 awarded Popular Question Mar 22 awarded Self-Learner Jan 11 comment How can a Cauchy sequence converge to an irrational number? In the last sentence, I think you meant "...a number is rational if and only if its decimal expansion repeats or terminates..."

Would you mind posting that as an answer? Jul 8 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. Jul 7 asked Maximum number of vertices in intersection of triangle with box Feb 11 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 $\vec v$. Jul 18 awarded Yearling Jun 30 comment Euler's formula for triangle mesh @BRabbit27 Fixed.
