WPF实现实现3D粒子波浪效果粒子波浪效果
本文实例为大家分享了WPF实现3D粒子波浪效果的具体代码，供大家参考，具体内容如下
实现效果如下：
步骤：步骤：
1、3D粒子类Particle.cs
public class Particle
{
public Point3D Position;//位置
public double Size;//尺寸
public int XIndex;//X位置标识
public int YIndex;//Y位置标识
}
2、粒子系统ParticleSystem类
public class ParticleSystem
{
private readonly List<Particle> _particleList;
private readonly GeometryModel3D _particleModel;
private readonly int SEPARATION = 100;
public ParticleSystem(int amountX, int amountY, Color color, int Size)
{
XParticleCount = amountX;
YParticleCount = amountY;
_particleList = new List<Particle>();
_particleModel = new GeometryModel3D { Geometry = new MeshGeometry3D() };
var e = new Ellipse
{
Width = Size,
Height = Size
};
var b = new RadialGradientBrush();
b.GradientStops.Add(new GradientStop(Color.FromArgb(0xFF, color.R, color.G, color.B), 0.25));
b.GradientStops.Add(new GradientStop(Color.FromArgb(0x00, color.R, color.G, color.B), 1.0));
e.Fill = b;
e.Measure(new Size(Size, Size));
e.Arrange(new Rect(0, 0, Size, Size));
Brush brush = null;
var renderTarget = new RenderTargetBitmap(Size, Size, 96, 96, PixelFormats.Pbgra32);
renderTarget.Render(e);
renderTarget.Freeze();
brush = new ImageBrush(renderTarget);
var material = new DiffuseMaterial(brush);
_particleModel.Material = material;
}
public int XParticleCount { get; set; }
public int YParticleCount { get; set; }
public Model3D ParticleModel => _particleModel;
private double _count = 0;
public void Update()
{
// 计算粒子位置及大小
for (int ix = 0; ix < XParticleCount; ix++)
{
for (int iy = 0; iy < YParticleCount; iy++)
{
foreach (var p in _particleList)
