Configuration

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

PropertyDefaultDescription
radius0The radius of the circle.

extends Primitive Configuration

The following configuration parameters are applicable to all primitive shapes.

PropertyDefaultDescription
position{ x: 0, y: 0 }A 2D vector representing the position of the primitive.
rotation0The rotation of the primitive (in degrees).
scale1The scale factor of the primitive.

Example Usage

ts
import {useCircle} from 'vuexyz'

const radius: Ref<number> = ref(50)
const { vertices, edges, faces } = useCircle({radius})

Returns

All primitive shapes return the following reactive members:

PropertyType DeclarationDescription
verticesComputedRef<Vertex[]>An array of all vertices.
edgesComputedRef<Edge[]>An array of all edges.
facesComputedRef<Face[]>An array of all faces.
centroidComputedRef<Vertex[]>The centroid (geometric center) of all vertices.
boundingBoxComputedRef<BoundingBox>The bounding box of the primitive, with properties x, y, width, height, maxX and maxY
svgPathComputedRef<string>An SVG path representing the shape of the primitive.
drawToCanvas(ctx: CanvasRenderingContext2D) => voidA method that draws the primitive to a canvas context.
