什么是我的shadowMap的问题？

Question

我的shadowMap太少了，问题是什么？

Answer 1

您可能没有设置阴影贴图相机（正确）。

From the docs:

  

默认为OrthographicCamera，左下角设为-5，右上角设为5，近剪裁平面为0.5，远剪裁平面为500。

含义：

yourLight.shadow.camera.left = -500 //(default is -5)
yourLight.shadow.camera.right = 500 //(default is 5)
yourLight.shadow.camera.top = -500 //(default is -5)
yourLight.shadow.camera.bottom = 500 //(default is 5)

//not sure if this is needed, the docs do not mention it even though they are changing the projection so probably not needed
yourLight.shadow.camera.updateProjectionMatrix()
