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
public Point3D Position;//位置 public double Width;//长方体底面宽 public double Height;//长方体侧面高
2、粒子系统ParticleSystem.cs
private readonly List<Particle> _particleList;
private readonly GeometryModel3D _particleModel;
private readonly int CUBOIDHEIGHT = 20;
private readonly int MOUSERADIUS = 1000;
private int XParticleCount;
private int YParticleCount;
public Model3D ParticleModel => _particleModel;
public ParticleSystem(int amountX, int amountY, Color color)
{
XParticleCount = amountX;
YParticleCount = amountY;
_particleList = new List<Particle>();
_particleModel = new GeometryModel3D { Geometry = new MeshGeometry3D() };
var material = new DiffuseMaterial(new SolidColorBrush(color));
_particleModel.Material = material;
}
public void SpawnParticle(double size)
{
// 初始化粒子位置和大小
for (int ix = 0; ix < XParticleCount; ix++)
{
for (int iy = 0; iy < YParticleCount; iy++)
{
var p = new Particle
{
Position = new Point3D(ix * size, iy * size, 0),
Width = size,
Height = CUBOIDHEIGHT,
};
_particleList.Add(p);
}
}
}
public void Update(Point mp)
{
foreach (var p in _particleList)
{
//求点到圆心的距离
double c = Math.Pow(Math.Pow(mp.X - p.Position.X, 2) + Math.Pow(mp.Y - p.Position.Y, 2), 0.5);
p.Height = (MOUSERADIUS / (c + CUBOIDHEIGHT)) * CUBOIDHEIGHT;
}
UpdateGeometry();
}
private void UpdateGeometry()
{
var positions = new Point3DCollection();
var indices = new Int32Collection();
for (var i = 0; i < _particleList.Count; ++i)
{
var positionIndex = i * 8;
var p = _particleList[i];
var p1 = new Point3D(p.Position.X, p.Position.Y, p.Position.Z);
var p2 = new Point3D(p.Position.X + p.Width, p.Position.Y, p.Position.Z);
var p3 = new Point3D(p.Position.X + p.Width, p.Position.Y + p.Width, p.Position.Z);
var p4 = new Point3D(p.Position.X, p.Position.Y + p.Width, p.Position.Z);
var p5 = new Point3D(p.Position.X, p.Position.Y, p.Position.Z + p.Height);
var p6 = new Point3D(p.Position.X + p.Width, p.Position.Y, p.Position.Z + p.Height);
var p7 = new Point3D(p.Position.X + p.Width, p.Position.Y + p.Width, p.Position.Z + p.Height);
var p8 = new Point3D(p.Position.X, p.Position.Y + p.Width, p.Position.Z + p.Height);
