Unity模型剖切
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
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
修改结果如下 代码很长就折叠了

修改完之后就是效果展示的样子了
项目Hierarchy截图 用的就是插件里面带的demo
最后再把插件修改过后的资源包发一下吧,以免其他小伙伴出错
亲测2021.3.4可以打包
二. 1.之后又更改了既可以滑动条模型剖切,也可以鼠标点击模型进行剖切

2.再加一个自动设置剖切的脚本
using System.Collections; using System.Collections.Generic; using UnityEngine; using WorldSpaceTransitions; public class AutoSheScript : MonoBehaviour { public GameObject pouqieObj; public SectionSetup sectionSetup_; public CappedSectionBox cappedSectionBox_; // Start is called before the first frame update void Start() { //模型标签"PouQie" pouqieObj = GameObject.FindGameObjectWithTag("PouQie"); } //执行剖切 剖切框就会自动设置好 public void Perform_Cutting() { sectionSetup_.model = pouqieObj; sectionSetup_.RecalculateBounds(); sectionSetup_.CheckShaders(); sectionSetup_.CreateSectionMaterials(); cappedSectionBox_.GetSliderData(); } // Update is called once per frame void Update() { if (Input.GetKeyDown (KeyCode.Space)) { Perform_Cutting(); } } }
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 /// </summary> /// <param name="aa"></param> public void SetingValue(float aa) { 滑动条按下(1); float lsx = startScale.x; float lsy = startScale.y; float lsz = startScale.z; Vector3 onDrag = new Vector3(yAxis.transform.position.x, CalculateBFB(aa), distance); Vector3 translation = onDrag - startDrag; Vector3 projectedTranslation = Vector3.zero; projectedTranslation = Vector3.Project(translation, transform.up); transform.position = startPos + 0.5f * (projectedTranslation.normalized * translation.magnitude); lsy += translation.magnitude * Mathf.Sign(Vector3.Dot(projectedTranslation, transform.up)); transform.localScale = new Vector3(Mathf.Clamp(lsx, 0.01f, Mathf.Infinity), Mathf.Clamp(lsy, 0.01f, Mathf.Infinity), Mathf.Clamp(lsz, 0.01f, Mathf.Infinity)); } float CalculateBFB(float aa) { float CAL = (sliderY.maxValue - sliderY.minValue) * aa/100+ sliderY.minValue; return CAL; }
