Perspective, a game for the 'viewpoint' assignment by Alyssa Reuter
My intent was to make a game in which the only control the player has is changing his perspective of the scene in order to hit a hidden goal sphere.
The main mechanic is rotating the quaternion-based camera using the keyboard. X rotation is controlled by W and S, Y by A and D, and Z by Q and E. Once the player picks the perspective from which he thinks he can reach his the goal, he clicks the mouse button to launch himself through the space.
This game is a little bit like golf, except it's in 3D space instead of on a 3d plane, which I haven't seen before. There's also an element of luck.
I didn't get as far as I would have liked with this--ideally you would also be able to bounce off the walls instead of going through them. However, I was able to implement a solid quaternion-based camera, which satisfies the perspective mechanic.
