Interface PointData4D

Minimal { x, y, z, w } shape that 4D math methods accept

Any plain object with these four numbers can be passed in place of a full Vector4.

const p: PointData4D = { x: 1, y: 2, z: 3, w: 1 };

const v4 = new Vector4();
v4.copyFrom(p);

interface PointData4D {
    w: number;
    x: number;
    y: number;
    z: number;
}

Properties

w: number

Fourth component, by convention 1 for a position and 0 for a direction

const behindCamera = clip.w <= 0;

x: number

The x component

const clip = new Vector4(point.x, point.y, point.z, 1).applyMatrix4(camera.viewProjection);
const screenX = clip.x / clip.w;

y: number

The y component

const screenY = clip.y / clip.w;

z: number

The z component

const depth = clip.z / clip.w;
