ThreeJS奇怪的条纹阴影

问题描述

我正在尝试让厨房内的房间光线充足 http://bozoou.com/plocice3D/您可以注意到厨房元素上奇怪的水平阴影.

I am trying to make room light inside this kitchen http://bozoou.com/plocice3D/You can notice wierd horizontal strikes of shadow on kitchen element.

我怀疑在 x、y 和 z 轴顶部的聚光灯中.如果我沿 y 轴仅将光源移动 1 个点(房间为 500x300)，我会在整个地板上看到这种阴影:http://bozoou.com/plocice3D/?moveLight=1如果我将灯光移动 1 或 50，也会发生同样的问题.

I have suspect in spotLight which is in middle of x,y, and top of z axis.If I move source of light for only 1 point along y-axis (room is 500x300), I got this strikes of shadow on whole floor: http://bozoou.com/plocice3D/?moveLight=1Same problem happens if I move light for 1 or 50.

所有元素投射和接收阴影.

All elements cast and receive shadow.

推荐答案

这个问题通常是由于阴影近点离你的物体太近造成的.为了更好地理解，请尝试执行以下操作:创建灯光后，您可以添加一个相机助手来显示灯光的边界.

This problem is usualy caused by the shadow near point is too close to your object.For better understanding try to do the follow:after you create your light you can add a camera helper to show you the bounderies of the light.

var spotLight = new THREE.SpotLight(0xffffff, 0.3, 0, Math.PI / 2);
spotLight.position.set(0, 100, 0);
sunLight.castShadow = true;

var shadowCameraHelper = new THREE.CameraHelper(spotLight.shadow.camera);
shadowCameraHelper.visible = true;

Kepp 更改这两个值，直到您达到目标.

Kepp changing these two values untile you reach your goal.

spotLight.shadow.camera.near = 50;
spotLight.shadow.camera.far = 150;

请记住，spotLight.shadow.camera.far 设置得越多，阴影就越模糊.

Keep in mind that the more you set spotLight.shadow.camera.far the more that shadow will be fuzzy and blury.
