FLASH: Slightly OT: formula for calculating distance?

[Flannagan, Craig]

Slightly OT, but it will help me make semi-3D stuff in Flash:


Hypothetical situation for you math buffs -


Let's say I have a square, 10m each side, in 3D space.


I push the square away from me 1m. 


So the illusion in Flash I should create is, naturally, a smaller square.


BUT, how do I calculate how much smaller it get, in 2D space? (for example,

I tell the scale function to reduce size by .75 <--- this is the number I

want)


Is there a mathematical formula for this?


Thanks,

Craig
