This feature would allow you to interact with the static PDF pages to see real-time anatomical shifts:

: Each pose is typically broken down into four side-by-side views: Skin Layer : The final surface form. Color-Coded Muscles

The book uses clear, color-coded 3D renders and overlaid diagrams, not just photographs or dry medical illustrations. This visual language is designed specifically for sculptors: you see the bone, then the muscle, then the skin form in a direct, buildable sequence.

: Instead of just showing a bicep in isolation, the book explores how it changes shape during extension, flexion, and rotation. The Block-Out Method
