Perspective - research and practice sheet

Confusing, isn't it? Well, it's not a tutorial, but as the title says, my research and practice sheet. You actually don't need to understand that whole geometry and math stuff, at all. ^_^'
I highly recommend that you watch my YouTube tutorial videos, where I explain everything clearly, step by step:

One Point Perspective: www.youtube.com/watch?v=bzgpjK…

Two Point Perspective: www.youtube.com/watch?v=9w_v4Y…

Three Point Perspective: www.youtube.com/watch?v=e2j3rx…

And here are the calculators you can use for getting all the values you need. In the videos I also explain how to use them:
1PP: goo.gl/Y7tOhH
2PP: goo.gl/OZs6s1
3PP: goo.gl/sFz4Ox  
    and for the MPs three separate links, because I haven't found a better calculator...
    goo.gl/ZWzxhi   ->   goo.gl/WsaMvd   ->    goo.gl/wssfoQ
Please let me know if you got a better online calculator for extremely long formulas/tons of variables.

If you want to know what literature, links and/or videos I used for a particular technique, then just send me a message.
