效果展示
1.首先先下载一个模型剖切插件Cross-Section插件 没有的下方链接自取
插件下载
2.下载之后导入到项目 导入之后的样子如下图
因项目需求需要剖切模型,要使用滑动条进行剖切,插件中有很多demo,其中就有使用滑动条的,可是只能进行单独一个面的剖切,换面操作模型会恢复原状,需求是可以同时操作三个面剖切,模型不恢复原状
最后只能在插件里面修改
修改了CappedSectionBox这个脚本

void Start()
{
//模型标签"PouQie"

}
//执行剖切 剖切框就会自动设置好

{
sectionSetup_.model = pouqieObj;

cappedSectionBox_.GetSliderData();
}
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown (KeyCode.Space))
{

}
}
}自动设置剖切
3.新加的功能,设置剖切的百分比固定参数,有需要可以添加,没有需要就不用添加 ,方法加到上面**修改的脚本**里面的最后即可(如图所示)
4.下面是添加的方法复制即可
/// <summary>
/// 传的参数是数字 这是Y轴剖切的,其他轴可以自行添加
