useLine

Composable for working with lines comprised of two or more vertices.

Configuration

The useLine function accepts a single configuration object as an argument, where each property has a default value if not provided.

Property	Default	Description
vertices	[]	An array of two or more vertices.

extends Primitive Configuration

The following configuration parameters are applicable to all primitive shapes.

Property	Default	Description
position	{ x: 0, y: 0 }	A 2D vector representing the position of the primitive.
rotation	0	The rotation of the primitive (in degrees).
scale	1	The scale factor of the primitive.

Usage

import { useLine } from 'vuexyz'

const start: Ref<Vertex> = ref({ x: -100, y: -100 })
const end: Ref<Vertex> = ref({ x: 100, y: 100 })
const { vertices, edges, faces } = useLine({ vertices: [start, end]})

Returns

All primitive shapes return the following reactive members:

Property	Type Declaration	Description
vertices	ComputedRef<Vertex[]>	An array of all vertices.
edges	ComputedRef<Edge[]>	An array of all edges.
faces	ComputedRef<Face[]>	An array of all faces.
centroid	ComputedRef<Vertex[]>	The centroid (geometric center) of all vertices.
boundingBox	ComputedRef<BoundingBox>	The bounding box of the primitive, with properties x, y, width, height, maxX and maxY
svgPath	ComputedRef<string>	An SVG path representing the shape of the primitive.
drawToCanvas	(ctx: CanvasRenderingContext2D) => void	A method that draws the primitive to a canvas context.
threeShape	ComputedRef<THREE.Shape>	A THREE.Shape object representing the primitive's 2D face. Only applicable with closed shapes.
threeCurvePath	ComputedRef<THREE.CurvePath>	A THREE.CurvePath object representing the primitive's 2D edges. Can be used in three and tres.
