Portal Rotations

I've never seemed to figure out how the rotation of a portal makes you come out the other side really quickly, or it makes you come out regularly.

Re: Portal Rotations

The portal rotation dictates the direction of your momentum.
Consider these two portals linked to each other.

If you enter the second portal on the right from the bottom with speed V upwards, (I think) you will be pushed out of the first portal with speed V going left.
Similarly, if I enter the first portal from the right, I will be directed upwards from the second portal.

The part with the quick or normal exit is also caused by this. A quick exit happens if the direction(s) of your exit is open space. A "normal" exit happens if the direction of your exit is blocked by a wall, as it nullifies any speed you previously had in that direction, and if you only had speed in that direction, the result is 0 at the instant of your exit.
In the picture above, regardless of what speed I have, if I were to enter the second portal from the left, it will be nullified from the block directly in front of the direction I would have exited from the first portal, so I simply fall.

Re: Portal Rotations

To experience it, try making an array of portals with varying rotations to see how they all work.
