GridHelper

坐标格辅助对象，坐标格实际上是 2 维线数组。

GridHelper( size : number, divisions : Number, colorCenterLine : Color, colorGrid : Color )

size -- 坐标格尺寸. 默认为 10.
divisions -- 坐标格细分次数. 默认为 10.
colorCenterLine -- 中线颜色. 值可以为 Color 类型, 16进制和 CSS 颜色名. 默认为 0x444444
colorGrid -- 坐标格网格线颜色. 值可以为 Color 类型, 16进制和 CSS 颜色名. 默认为 0x888888

  renderer.render(scene, camera)
})

camera.position.z = 20
renderer.render(scene, camera)
