Absolutely. I remember when I was just coming out of linear algebra, ready to make games armed with this new math skill that I knew could use to create collision detection. I was scouring the web, looking for this library I knew had to exist... I mean it's a fundamental element of almost all software in the modern era. No luck, nothing, just little tidbits here and there, no full blown library that said give me some polylines and I'll tell you if they cross/collide. Was depressed lurking the HN boards when someone posted and article on box2d, and it fucking dawned on me, physics engines are one big glorious collision detection library. I immediately dug into how I could strip away the physics simulation and use the polygons for pure detection. 5 months later of started my career as a software engineer due to winning a 3month grant to make an educational game, all powered by box2d and my exploration of math, physics, and game design.
