VoxelField

Walkable surfaces as spans, in columns on a horizontal grid.

interface VoxelField

import type { VoxelField } from '@driftengine/nav';

In depth

Structure of arrays and CSR columns, matching NavGraph in core: a span is three integers and a column is a slice, so building a region out of this walks memory in order and allocates nothing per span.
