help with perspective

[LonelyTroll]

Loomis places the measuring points semi-randomly because placing them precisely isn't that important for visual art. You'll probably need a book on architectural perspective to get into the placement of measuring points, like "Architectural Sketching and Drawing in Perspective" on this page: http://www.survivorlibrary.com/index.php...%20drawing

Handprint's tutorial also goes into measuring points: https://www.handprint.com/HP/WCL/tech10.html

Let's just say it involves a compass (or making very large circles in a digital art program) and is very boring. As far as I know, you only truly need measuring points if you're translating a flat architectural plan to 3D. I've never heard of a professional artist using it. Even Scott Robertson's book only gives the typical rectangle multiplication method for creating grids (the one where you run a line through the corners of a square to the horizon line and use it as a diagonal vanishing point for making more squares).

thank you!
