I've used geometry to help develop commercial packaging for a toy similar to Zometool but using the Roger's Connection idea (open source) of ball bearings and magnets, called StrangeAttractor. Rather than use photographs, we used computer generated ray tracings, which look photorealistic, but are entirely the results of computation. Here's an example of the kind of graphics I did, using Python + POVRay + my knowledge of spatial geometry:

Ray tracing is the basis for rendertime movie making and is all geometry under the hood.
Real time gaming is likewise geometry, and because more interactive, is going to require fast vector operations, a kind of geometry.[1]
Most of those libraries have already been coded, so I'm not saying you should always expect to reinvent those same wheels, but if you're into computer gaming and/or animation, it's all geometry, color, lighting (and a soundtrack).
My 4D Studios also uses Camtasia Studio, other assets, to crank out videos for my Coffee Shops Network, a small group of cerebral coffee shops dedicated to sharing my school's esoterica on universitybased LCD screens or wherever (I don't always know).[2]

[1] lots of texts focus on rotation matrices, but more recently you'll find quaternions driving some of the more popular game engines  not traditionally a precollege topic but approachable in a sufficiently concrete mathematics curriculum e.g. IB.
