<div class="desc">A class for generating sphere geometries</div>
|
||
|
|
|
||
|
|
<h2>Example</h2>
|
||
|
|
|
||
|
|
<code>var geometry = new THREE.SphereGeometry( 5, 32, 32 );
|
||
|
|
var material = new THREE.MeshBasicMaterial( {color: 0xffff00} );
|
||
|
|
var sphere = new THREE.Mesh( geometry, material );
|
||
|
|
scene.add( sphere );
|
||
|
|
</code>
|

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]([page:Float radius], [page:Integer widthSegments], [page:Integer heightSegments], [page:Float phiStart], [page:Float phiLength], [page:Float thetaStart], [page:Float thetaLength])</h3>
|
||
|
|
|
||
|
|
<div>
|
||
|
|
radius — sphere radius. Default is 50.<br />
|
||
|
|
widthSegments — number of horizontal segments. Minimum value is 3, and the default is 8.<br />
|
||
|
|
heightSegments — number of vertical segments. Minimum value is 2, and the default is 6.<br />
|
||
|
|
phiStart — specify horizontal starting angle. Default is 0.<br />
|
||
|
|
phiLength — specify horizontal sweep angle size. Default is Math.PI * 2.<br />
|
||
|
|
thetaStart — specify vertical starting angle. Default is 0.<br />
|
||
|
|
thetaLength — specify vertical sweep angle size. Default is Math.PI.<br />
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<div>
|
||
|
|
The geometry is created by sweeping and calculating vertexes around the Y axis (horizontal sweep) and the Z axis (vertical sweep). Thus, incomplete spheres (akin to <em>'sphere slices'</em>) can be created through the use of different values of phiStart, phiLength, thetaStart and thetaLength, in order to define the points in which we start (or end) calculating those vertices.
|
||
|
|
</div>
|
||
|
|
|

|

||
|
|
<h2>Properties</h2>
|
||
|
|
|
||
|
|
<div>
|
||
|
|
Each of the contructor parameters is accessible as a property of the same name. Any modification of these properties after instantiation does not change the geometry.
|
||
