我正在开发化学模拟项目。我正在寻找水模拟。我从此示例http://waterstretch.ecoulon.com/
中提取了代码它使用Three.js r48，提取的代码完美无缺。现在我尝试将项目的工作代码升级到Three.js r52。该示例显示黑屏，没有任何控制台错误：O 我测试了Three.js r49和更新但没有帮助，我在更改日志中找不到任何有用的信息。 https://github.com/mrdoob/three.js#change-log
和迁移说明 https://github.com/mrdoob/three.js/wiki/Migration
这是代码

将此代码迁移到Three.js r52的任何帮助？
答案 0 :(得分：5)
似乎是纹理系统更改的问题：
纹理均匀变化：纹理单位现在自动分配， 纹理对象转到值属性而不是纹理对象{类型： “t”，值：0，texture：map} =＆gt; {type：“t”，value：map}
我想我在这个小提琴中解决了它：http://jsfiddle.net/gero3/UyGD8/9/
{ type: "t", value: 0, texture: map } => { type: "t", value: map }
