先上我的Demo效果图:
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); } } }
