H3DU.exports.SurfaceOfRevolution(curve, minval, maxval, [axis])
A surface evaluator object for a surface of revolution, which results by revolving a two-dimensional curve around an axis.
This class is considered a supplementary class to the Public Domain HTML 3D Library and is not considered part of that library.
Parameters
curve(Type: Object)
A curve evaluator object that describes a 2-dimensional curve to rotate about the axis of rotation, as specified in the "axis" parameter. The curve's X coordinates correspond to elevation, and its Y coordinates correspond to radius.If the curve function draws a curve that goes both above and below the axis of rotation, such as a circle or ellipse, the V coordinates given in minval and maxval must restrict the curve definition to no more than half of the curve.
minval(Type: number)
Smallest V coordinate.maxval(Type: number)
Largest V coordinate. If minval is greater than maxval, both values will be swapped.axis(Type: Array.<number>) (optional)
Axis of rotation, around which the curve will be rotated to generate the surface of revolution. If null, undefined, or omitted, the positive Z axis (0, 0, 1) will be the axis of rotation. This parameter is a 3-element array describing the X, Y, and Z coordinates, respectively, of a 3D point. The axis of rotation will run in the direction from the origin to the point given in this parameter. This parameter need not be a unit vector.
