<h2>代码示例</h2>
|
|
|
|
<code>
|
|
const sky = new Sky();<br />
|
|
sky.scale.setScalar( 450000 );<br />
|
|
|
|
const phi = MathUtils.degToRad( 90 );<br />
|
|
const theta = MathUtils.degToRad( 180 );<br />
|
|
const sunPosition = new Vector3().setFromSphericalCoords( 1, phi, theta );<br />
|
|
|
|
sky.material.uniforms.sunPosition.value = sunPosition;<br />
