maximum
Maximum number of intermediate edge intervals across a half-equator (PI radians) of arc. Per-edge subdivision count is scaled by edge length: steps = round(maximumNumEdgeIntervals * distanceRadians / PI), then further adjusted by polarThrottle near the poles for surface shapes. 3D shapes use the unthrottled count. A value of 0 disables intermediate vertex generation.
Default 64 gives ~10 intermediates on a 30° edge, fewer on shorter edges, more on longer ones. Increase for smoother long-edge great-circles, decrease for less assembly work in dense scenes.
