Reference grid
12 × 8
Cells across panel
12
Vertical rulings within each wall panel. These are the marks the skin must land on.
Cells up panel
8
Grid spacing
equal arc
equal flat
Rulings evenly spaced along the curved surface. The skin grid is pre-warped to match, so a flat render lands true.
Cap grid
polar
Rings
6
Concentric rulings from apex to rim. Ring spacing compensates for the pinch.
Spokes
16
Dead zone
14%
Radius around the apex where pinch exceeds usable detail. Keep composition out of it.
