Each panel spans 45.0° of the horizon.

Surplus rendered past the panel's true arc, hidden behind the neighbour's edge. Absorbs mismatch between separate renders.

Odd panels in front, even behind — every seam hidden equally.

Vertical band the wall panels cover, from floor to springline.

Height of the zenith cap above the springline. At 0 the dome is flat-topped.

Where the viewer stands. Sets the horizon line the panels must agree on.

Radial resolution of the disc. Higher is smoother under polar warp but costs vertices.

How far the cap's rim drops over the top of the wall panels.

Vertices per panel. Depth displacement needs density — under 32 the topography reads as facets.

Inward displacement the depth map will drive. Set the budget here — the warper must keep topography inside it.
