Spatial Thinking
Think like a sculptor working in time. Your characters exist in three-dimensional space, even on a 2D screen. Every frame is a frozen moment in a world with depth.
Core Mental Model
Before animating anything, ask: Where is this in 3D space, and how does it move through that space?
Animation is 4D: three spatial dimensions plus time. Characters have fronts and backs. Rooms have depth. Actions travel along vectors through real (imagined) environments.
The 12 Principles Through Dimension
Solid Drawing — The foundation of spatial thinking. Every object has volume. Turn it around in your mind. Know what the back looks like. Draw through forms, not around them.
Arcs — All movement happens in 3D space. An arm swinging traces a curve through depth, not just across the screen. Think spherical paths, not flat shapes.
Staging — Spatial composition. Where in the Z-axis is each element? Foreground, midground, background create depth. Overlap establishes position in space.
Squash & Stretch — Deformation happens in 3D. When a ball squashes, it spreads outward in all directions, not just sideways. Maintain volume in depth.
