Scheme

Preset plotting schemes for common graphics and tactical arrows.

Each export in this module is a PlotScheme object that can be passed directly to usePlot().operate().

That means a scheme is not just a shape. It also defines:

• the initial Cesium entity or entities to render
• how the shape updates while the mouse moves
• when the plot is considered complete
• which skeletons are attached for editing the sampled positions

Exports

Tactical arrows

Export	Purpose

PlotSchemePolygonArrowUnitCombatOperationTailed	Tailed unit-combat-operation arrow scheme
PlotSchemePolygonAssemblingPlace	Assembling-place arrow scheme

How to think about them

• Basic graphics are the simplest schemes. They usually create one entity and keep it in sync with the sampled position or positions.
• Paths and polygons add vertex editing, midpoint insertion, and shape closure logic on top of the base render loop.
• Tactical arrow schemes lean on @vesium/geometry to turn sampled coordinates into more specialized polygon shapes.
• If you need interaction, pair a scheme with the skeletons it exports or composes internally.

Usage

const { operate } = usePlot();

await operate(PlotSchemePolygon);
await operate(PlotSchemePolygonArrowStraight);
