How to Check If Two Triangles Intersect: Geometric Algorithms Explained
I’ve looked at a lot of triangle-triangle intersection code across different projects. And every time, one thing stood out: there’s no single implementation that covers all the edge cases. That’s not surprising. The requirements vary wildly depending on the use case – fast-and-loose for games, watertight for CAD, approximated for physics engines. But in this Continue reading

Is the Point Inside the Triangle?
Today we’re tackling something that seems simple: how do you tell if a point is inside a triangle? I’ve got five things I want to do here: Make it a storyThis post will be long, with some detours and extra thoughts. But I think that’s the best way to get tricky stuff. A story keeps Continue reading
