示例2: distanceToPlane

/**
 * Computes distance from ray's origin to the plane
 *
 * @param ray
 * @returns zero if ray is coplanar with plane, null if something strange
 * happened, scalar value representing distance from ray's origin to the
 * plane if everything is OK
 */
function distanceToPlane(ray: Ray) {
    var denominator = numeric.dot(slicingPlaneNormal, ray.direction)
    if (denominator === 0) {
        // ray is coplanar, return 0
        return distanceToPoint(ray.origin) === 0 ? 0 : null
    }

    var t = -(numeric.dot(ray.origin, slicingPlaneNormal)) / denominator
    return t >= 0 ? t : null
