## A quick, possibly stupid, question about perspective

O.K. For some reason I've never been given a straight answer to this perspective question, and I'm sure I'm the only one who doesn't know the answer.
Using 2-point perspective, how do you know when the square you've drawn is equalateral. I've always had to just eyeball it, and never knew the proper way of doing it. Thanks is advance. D

The stuff from the post above feels very confusing to me.. I think this may be useful.

I would like to know if the measuring points (1 or 2?) must be placed very exactly to work as advertised? Because Mr. Loomis just says to put them (it?) close to the vertical scale. And does it matter if its left or right of vertical scale. So do I just have to know the stuf from Mr. Loomis book or is the new info from the post above more accurate?

Hi,

The approach Andrew Loomis uses is based on what looks good to the eye - basically you can move the measuring points close or further away from the vertical scale to you get the perspective you want - so it looks right. The further away the measuring point is from the vertical scale the greater the perspective reduction - if it's too far away, your perspective will look very odd, try it. This is why Andrew Loomis says keep it near the vertical scale. Basically it takes a bit of practice to get it to looking right.

You can work out the exact position of the measuring points by using a method such as the one explained here:

Hope that was of some use
