    Interface LassoSelect

    A 2D polygon: every used vertex whose projection falls inside it. Project your screen-space polygon to mesh-local coordinates with your camera first; axis picks the projection plane.

    interface LassoSelect {
        axis?: "xy" | "xz" | "yz";
        kind: "lasso";
        polygon: Float32Array<ArrayBufferLike> | readonly number[];
    }
    Index
    axis?: "xy" | "xz" | "yz"

    The local plane projected onto. Defaults to "xy".

    kind: "lasso"
    polygon: Float32Array<ArrayBufferLike> | readonly number[]

    Flat [x0, y0, x1, y1, ...] polygon corners in local coordinates.
