Pandora Wrigglesworth's Portable Door Generator - Physics with panache

Today, Pandora Wrigglesworth will be releasing her newest product, The Portable Door Generator. She teleported me to a room yesterday and asked, "The door is behind you but, how would you get out of the room if there were no door?" She went on to explain, "With my new device, you don't have to rely on the architect's choice of where to put a door."

She activated the mechanism, and with a swirl of particles, a new door magically appeared, when none had been there before.




And just like that, Pandora walked through a door of her own creation...

Pandora went on to say that "It works on any solid surface. It doesn't have be just walls. It does require rez perms but it is temp rez so prim limits aren't an issue. It works on walls up to about 5 meters thick and doesn't have trouble with walls being different angles on the other side. There are five different kinds of doors chosen at random."

How does it work?
Pandora Wrigglesworth: Rezzing the doors and linking them up was easy. It was detecting *where* to rez them that was tricky. There is no LSL command to detect the shape of a prim in other objects, so I rez small invisible prims and bounce them off the walls and then through the walls like sonar. They move until they hit a wall and that's where one door goes. Then they drill through the wall until they stop colliding with it and that's where the other door goes. There are three prims and then I use a little matrix algebra to determine the rotations and positions from that. They are self-deleting. I'd hate to see them stack up in the Lost and Found folder!

Please note: This device is also handy when you fall down underneath a building on a bad teleport.

All proceeds from the sale of Pandora's items benefit her Global Domination Fund. You can pick up the Portable Door Generator at Pandora's shop, Curio Obscura, by teleporting directly from here.
