中文说明 ##Introduction Customized a drawing utility class which supports graphic drawing in the sceneview. Supported geometry types includes: point, line, polygon, circle, circle segments, bezier polygon, bezier line, arrow and multi-head arrow. It also supports turn a polygon geometry type into a cubic. The support for drawing dashed line is experimental (it is implemented using three.js) it does not support customize of the line width.

##Introduction You can reference the Draw class using relative path(the other scripts all needed to be included in the script/ folder, which draw class referenced using relative path in ths internal implementation)

require(["./script/Draw"], function(Draw) { /* code goes here */ });	

###Constructor:

new Draw({view: viewInstance, gl: graphicsLayerInstance})

The Draw class's constructor accept a object which contains a view property and gl property. The view property needs to point to the SceneView instance, the gl property need to point to a GraphicsLayer instance.

###Static Properties

###Drawing method draw.activate(Draw.CURVE) calling the corresponding method can active the drawing of the specified geometry.

draw.activate(Draw.CUBE) after calling this method, the next click on the polygon will turn the polygon into a cubic (move the mouse up and down to adjust the height of the cubic).

draw.deactivate() End drawing.
