You should control it by changing the sourceOffset and destOffset parameters.\n *\n *\n * LightningStrike parameters\n *\n * The paramsObject can contain any of the following parameters.\n *\n * Legend:\n * 'LightningStrike' (also called 'ray'): An independent voltaic arc with its ramifications and defined with a set of parameters.\n * 'Subray': A ramification of the ray. It is not a LightningStrike object.\n * 'Segment': A linear segment piece of a subray.\n * 'Leaf segment': A ray segment which cannot be smaller.\n *\n *\n * The following parameters can be changed any time and if they vary smoothly, the ray form will also change smoothly:\n *\n * @param {Vector3} sourceOffset The point where the ray starts.\n *\n * @param {Vector3} destOffset The point where the ray ends.\n *\n * @param {double} timeScale The rate at wich the ray form changes in time. Default: 1\n *\n * @param {double} roughness From 0 to 1. The higher the value, the more wrinkled is the ray. Default: 0.9\n *\n * @param {double} straightness From 0 to 1. The higher the value, the more straight will be a subray path. Default: 0.7\n *\n * @param {Vector3} up0 Ray 'up' direction at the ray starting point. Must be normalized. It should be perpendicular to the ray forward direction but it doesn't matter much.\n *\n * @param {Vector3} up1 Like the up0 parameter but at the end of the ray. Must be normalized.\n *\n * @param {double} radius0 Radius of the main ray trunk at the start point. Default: 1\n *\n * @param {double} radius1 Radius of the main ray trunk at the end point. Default: 1\n *\n * @param {double} radius0Factor The radius0 of a subray is this factor times the radius0 of its parent subray. Default: 0.5\n *\n * @param {double} radius1Factor The radius1 of a subray is this factor times the radius1 of its parent subray. Default: 0.2\n *\n * @param {minRadius} Minimum value a subray radius0 or radius1 can get. Default: 0.1\n *\n *\n * The following parameters should not be changed after lightning creation. They can be changed but the ray will change its form abruptly:\n *\n * @param {boolean} isEternal If true the ray never extinguishes. Otherwise its life is controlled by the 'birthTime' and 'deathTime' parameters. Default: true if any of those two parameters is undefined.\n *\n * @param {double} birthTime The time at which the ray starts its life and begins propagating. Only if isEternal is false. Default: None.\n *\n * @param {double} deathTime The time at which the ray ends vanishing and its life. Only if isEternal is false. Default: None.\n *\n * @param {double} propagationTimeFactor From 0 to 1. Lifetime factor at which the ray ends propagating and enters the steady phase. For example, 0.1 means it is propagating 1/10 of its lifetime. Default: 0.1\n *\n * @param {double} vanishingTimeFactor From 0 to 1. Lifetime factor at which the ray ends the steady phase and begins vanishing. For example, 0.9 means it is vanishing 1/10 of its lifetime. Default: 0.9\n *\n * @param {double} subrayPeriod Subrays cycle periodically. This is their time period. Default: 4\n *\n * @param {double} subrayDutyCycle From 0 to 1. This is the fraction of time a subray is active. Default: 0.6\n *\n *\n * These parameters cannot change after lightning creation:\n *\n * @param {integer} maxIterations: G
