Class EFieldNode¶

import { EFieldNode } from 'scenerystack/scenery-phet';

Constructor¶

new EFieldNode( capacitor, modelViewTransform, maxEffectiveEField, canvasBounds )¶

Instance Methods¶

paintCanvas( context )¶

Rendering @public

@param {CanvasRenderingContext2D} context

getLineSpacing( effectiveEField )¶

Gets the spacing of E-field lines. Higher E-field results in higher density, therefore lower spacing. Density is computed for the minimum plate size. @public

@param {number} effectiveEField @returns {number} spacing, in model coordinates
