DEPTH_OFFSET_SIGN

Which way a polygon offset has to push to bring a coplanar overlay forward.

Explained in Hello world.

const DEPTH_OFFSET_SIGN: number
import { DEPTH_OFFSET_SIGN } from '@driftengine/core';

In depth

The sign flips with the compare and forgetting it is silent. POLYGON_OFFSET_FILL adds to depth; under LESS nearer is smaller, so an overlay is pulled forward with a negative offset, and under GREATER nearer is larger and the same nudge pushes it behind the surface it is meant to sit on. The symptom is a marking that disappears into the road rather than a marking that fights, which reads as a missing draw call.
