Topic: a 3d camera
+Anonymous A — 4.9 years ago #58,665
hello anyone ever use 2d software creator like unity or frebasic editor? basically programming... i am looking for a way to program a 3d camera, but i dont know how to or if the way i do i correct...
like i am writing a camera with position and angle, having variables like posxyz and rotxyz, and then camera with u and v, and i dont know how to connect thede two elements, with u and v moving along with posxyz and rotxyz in a certain value that is consistent
also defining if object should be visible when in front camera and vice versa? what do i do to avoid object behind me appearing in front of me?

You can either use Euler rotations, and construct rotation matrices for pitch, yaw and roll, or implement quaternions. Euler rotations are easier but suffer from a problem called gimble lock. Quaternions are more difficult but are the best way to go about it.
First learn what a transformation matrix is though.

All that, and $4.89 plus tax will get you a small coffee at Starbucks.
