接下来想做一个图廊，所以并没有必要用立方体，只需做一些“墙壁”就行了。
而在一个平面上建起另一个矩形的平面，实则非常容易，只需输入墙角的两点和高度就可以了，这对于写过正方体的人来说绝对是简单得很，无非是把四个点劈成两个三角形
private MeshGeometry3D MakeSurface(Point3D p0, Point3D p1, Point3D p2, Point3D p3){ MeshGeometry3D mesh = new MeshGeometry3D(); Point3D[] pts ={p0, p1, p2, p3}; foreach (var pt in pts) mesh.Positions.Add(pt); foreach (var i in new int[6] { 0, 1, 2, 2, 3, 0 }) mesh.TriangleIndices.Add(i); return mesh;}接下来可以像之前做正方体时那样，先做一个平的地面，然后在地面上放置一些正方体。
由于地面上的正方形要求垂直于地面，所以重载一下
private MeshGeometry3D MakeSurface(Point p0, Point p1, double high){ return MakeSurface( new Point3D(p0.X, 0, p0.Y), new Point3D(p1.X, 0, p1.Y), new Point3D(p1.X, high, p1.Y), new Point3D(p0.X, high, p0.Y));}然后生成模型
代码为
private void DefineModel(Model3DGroup group){ // Make the ground. const double wid = 10; MeshGeometry3D groundMesh = MakeSurface( new Point3D(-wid, 0, -wid), new Point3D(-wid, 0, +wid), new Point3D(+wid, 0, +wid), new Point3D(+wid, 0, -wid)); DiffuseMaterial groundMaterial = new DiffuseMaterial(Brushes.DarkGray); GeometryModel3D groundModel = new GeometryModel3D(groundMesh, groundMaterial); group.Children.Add(groundModel); MaterialGroup gpMaterial; for (int x = -2; x <= 2; x += 2) { for (int y = -2; y <= 2; y += 2) { MeshGeometry3D mesh = MakeSurface(new Point(x, y), new Point(x, y + 1), 1); byte r = (byte)(128 + x * 50); byte g = (byte)(128 + y * 50); byte b = (byte)(128 + x * 50); Color color = Color.FromArgb(255, r, g, b); DiffuseMaterial material = new DiffuseMaterial( new SolidColorBrush(color)); GeometryModel3D model = new GeometryModel3D(mesh, material); group.Children.Add(model); } }}接下来就是挂载贴图，结果大致如下
其方法也很简单，就是把material变成想要的图片，故而先把图像放在一个字符串数组里
static readonly string[] imgs = new string[9]{ "2d1.png","2d2.png","2d3.png","2d4.png","2d5.png", "2d6.png","2d7.png","2d8.png","2d9.png"};接下来需要注意一点，图像本身需要一个坐标系，故而要把墙壁的代码改为
private MeshGeometry3D MakeSurface(Point p0, Point p1, double high, string uri = null){ var mesh = MakeSurface( new Point3D(p0.X, 0, p0.Y), new Point3D(p1.X, 0, p1.Y), new Point3D(p1.X, high, p1.Y), new Point3D(p0.X, high, p0.Y)); //这四个点代表图像上的坐标和图形中点的对应关系 Point[] textureCoods = new Point[4] { new Point(0, 1),new Point(1, 1), new Point(1, 0),new Point(0, 0), }; foreach (var pt in textureCoods) mesh.TextureCoordinates.Add(pt); return mesh;}然后在生成正方形时，用图像取代颜色
ImageBrush imgBrush = new ImageBrush();imgBrush.ImageSource = new BitmapImage(new Uri( $"imgs//{imgs[k++]}", UriKind.Relative));MeshGeometry3D mesh = MakeSurface(new Point(x, y), new Point(x, y + 1), 1);GeometryModel3D model = new GeometryModel3D(mesh, new DiffuseMaterial(imgBrush));group.Children.Add(model);“基于WPF如何实现3D画廊动画效果”的内容就介绍到这里了，感谢大家的阅读。如果想了解更多行业相关的知识可以关注编程网网站，小编将为大家输出更多高质量的实用文章！
