WPF实现3D立方体波浪墙效果

本文实例为大家分享了WPF实现3D立方体波浪墙效果的具体代码，供大家参考，具体内容如下

实现效果如下：

思路：仿照3D粒子系统，将粒子颗粒的Geometry改造为立方体，鼠标移动时将鼠标位置转为3D场景中的坐标。

步骤：

1、粒子类Particle.cs

publicPoint3DPosition;//位置
publicdoubleWidth;//长方体底面宽
publicdoubleHeight;//长方体侧面高

2、粒子系统ParticleSystem.cs

privatereadonlyList_particleList;
privatereadonlyGeometryModel3D_particleModel;
privatereadonlyintCUBOIDHEIGHT=20;
privatereadonlyintMOUSERADIUS=1000;
privateintXParticleCount;
privateintYParticleCount;
publicModel3DParticleModel=>_particleModel;

publicParticleSystem(intamountX,intamountY,Colorcolor)
{
XParticleCount=amountX;
YParticleCount=amountY;

_particleList=newList();
_particleModel=newGeometryModel3D{Geometry=newMeshGeometry3D()};
varmaterial=newDiffuseMaterial(newSolidColorBrush(color));
_particleModel.Material=material;
}

publicvoidSpawnParticle(doublesize)
{
//初始化粒子位置和大小
for(intix=0;ix
3、主窗体调用
xaml：
















交互逻辑：
privatereadonlyParticleSystem_ps;
privateDispatcherTimer_frameTimer;
privatePointpMouse=newPoint(9999,9999);

publicMainWindow()
{
InitializeComponent();

_frameTimer=newDispatcherTimer();
_frameTimer.Tick+=OnFrame;
_frameTimer.Interval=TimeSpan.FromMilliseconds(100);
_frameTimer.Start();

_ps=newParticleSystem(30,30,Colors.White);
WorldModels.Children.Add(_ps.ParticleModel);
_ps.SpawnParticle(50);

KeyDown+=Window_KeyDown;
}

privatevoidWindow_KeyDown(objectsender,KeyEventArgse)
{
if(e.Key==Key.Escape)
Close();
}

privatevoidOnFrame(objectsender,EventArgse)
{
_ps.Update(pMouse);
}

privatevoidGrid_MouseMove(objectsender,MouseEventArgse)
{
Pointmouseposition=e.GetPosition(myViewport);
PointHitTestParameterspointparams=newPointHitTestParameters(mouseposition);
VisualTreeHelper.HitTest(myViewport,null,HTResult,pointparams);
}

///
///获取鼠标在场景中的3D坐标
///
publicHitTestResultBehaviorHTResult(System.Windows.Media.HitTestResultrawresult)
{
RayHitTestResultrayResult=rawresultasRayHitTestResult;
if(rayResult!=null)
{
RayMeshGeometry3DHitTestResultrayMeshResult=rayResultasRayMeshGeometry3DHitTestResult;
if(rayMeshResult!=null)
{
GeometryModel3Dhitgeo=rayMeshResult.ModelHitasGeometryModel3D;
MeshGeometry3Dhitmesh=hitgeo.GeometryasMeshGeometry3D;
Point3Dp1=hitmesh.Positions.ElementAt(rayMeshResult.VertexIndex1);
doubleweight1=rayMeshResult.VertexWeight1;
Point3Dp2=hitmesh.Positions.ElementAt(rayMeshResult.VertexIndex2);
doubleweight2=rayMeshResult.VertexWeight2;
Point3Dp3=hitmesh.Positions.ElementAt(rayMeshResult.VertexIndex3);
doubleweight3=rayMeshResult.VertexWeight3;
Point3DprePoint=newPoint3D(p1.X*weight1+p2.X*weight2+p3.X*weight3,p1.Y*weight1+p2.Y*weight2+p3.Y*weight3,p1.Z*weight1+p2.Z*weight2+p3.Z*weight3);
pMouse=newPoint(prePoint.X,prePoint.Y);
}
}
returnHitTestResultBehavior.Continue;
}

privatevoidGrid_MouseLeave(objectsender,MouseEventArgse)
{
pMouse=newPoint(9999,9999);
}
