实现原理:

      WPF里面的3D物体均是由一个个三角面拼装起来的。网上很多公开的球体构建算法,可以很轻易的获取到。我得到所有3D球构成的顶点(Point3D)后,在球体的外层附件上一层内容即可到达上述gif图的效果。  每一个附加元素的坐标即构建3D球的三维坐标。

     如上文,在顶点位置上放5px * 5px的Ellipse即可构建点云,在顶点位置放置ModelVisual3D,材质贴图加载Image,即呈现照片球的效果。

     最后给Camera加一个旋转动画。

     关键源码:

     

       private void CreateElementss()
        {
            Vector3D oVectorCenter = new Vector3D(0, 0, PointRadius);

            int nImgIndex = -1;
            for (int stack = 0; stack <= Stacks; stack++)
            {
                double phi = Math.PI / 2 - stack * Math.PI / Stacks;
                double y = PointRadius * Math.Sin(phi);
                double scale = -PointRadius * Math.Cos(phi);

                for (int slice = 0; slice <= Slices; slice++)
                {
                    double theta = slice * 2 * Math.PI / Slices;
                    double x = scale * Math.Sin(theta);
                    double z = scale * Math.Cos(theta);

                    Vector3D oPoint = new Vector3D(x, y, z);

                    InteractiveCustom3DPlane o3DPlane = new InteractiveCustom3DPlane(0.3, 0.24, 0, 0);
                    o3DPlane.OffsetX = oPoint.X;
                    o3DPlane.OffsetY = oPoint.Y;
                    o3DPlane.OffsetZ = oPoint.Z;

                    nImgIndex++;
                    Border bdr = new Border() { Width = 5, Height = 5 };
                    bdr.Tag = nImgIndex;
                    string sImgFile = this.GetImg(nImgIndex);
                    Image img = new Image();
                    img.Stretch = Stretch.Fill;
                    BitmapImage bitmap = new BitmapImage();
                    bitmap.DecodePixelWidth = 100;
                    bitmap.DecodePixelHeight = 100;
                    bitmap.BeginInit();
                    bitmap.UriSource = new Uri(sImgFile);
                    bitmap.EndInit();
                    bdr.MouseLeftButtonUp += Bdr_MouseLeftButtonUp;

                    img.Source = bitmap;
                    bdr.Child = img;
                    o3DPlane.Visual = bdr;
                    this.Mv3dContent.Children.Add(o3DPlane);
                }
            }
        }
