Master the Cube, Master 3D Space

Summary by Krater

This perspective drawing tutorial demonstrates advanced techniques for drawing cubes accurately without reference, including methods for testing proportions, placing circles and ellipses on cube faces, and using diagonal vanishing points.

Answers: How do I draw cubes in perspective without reference?

• drawing cubes without reference
• foreshortening perspective
• placing circles on cube faces
• diagonal vanishing points

What it concludes

• Only a trained eye can control a true square in perspective.
• A square is the constant and true source of measure to eyeball proportions.
• When a rectangle's dimensions are uncommon, it is hard to discern if they are accurate, but a 1:1 square is easy to spot.
