如何旋转3D对象

本文介绍了如何旋转3D对象的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 大家好。 在我的应用程序中我有3D立方体。 在立方体边上我会放置任何控件。 在边界我有一个按钮可以将这个立方体旋转到+ -90度。 但实际上我已经旋转了相机，而不是立方体。而且我想完全旋转立方体。 < Window.Resources> < DiffuseMaterial x：Key =CubeSideMaterialViewport2DVisual3D.IsVisualHostMaterial =TrueBrush =LimeGreen/> < LinearGradientBrush x：Key =BlackBackgroundEndPoint =1,0StartPoint =0,0.3> < GradientStop Color =LightGrayOffset =0.8/> < GradientStop Color =DarkGrayOffset =0.7/> < GradientStop Color =BlackOffset =0/> < / LinearGradientBrush> < LinearGradientBrush x：Key =GreenBackgroundEndPoint =0.5,1StartPoint =0.5,0> < GradientStop Color =GreenYellowOffset =0.824/> < GradientStop Color =DarkGreenOffset =0/> < / LinearGradientBrush> < LinearGradientBrush x：Key =PressedButtonEndPoint =0.5,1StartPoint =0.5,0MappingMode =RelativeToBoundingBox> < GradientStop Color =BlueOffset =0/> < GradientStop Color =WhiteOffset =0.816/> < GradientStop Color =VioletOffset =0.744/> < / LinearGradientBrush> < ControlTemplate x：Key =ButtonLook> < Grid Background =KhakiShowGridLines =True> <矩形x：名称=矩形宽度=20高度=11> < Rectangle.Stroke> < LinearGradientBrush EndPoint =0.5,1StartPoint =0.5,0> < GradientStop Color =BlackOffset =1/> < GradientStop Color =Green/> < / LinearGradientBrush> < /Rectangle.Stroke> < Rectangle.Fill> < LinearGradientBrush EndPoint =0.5,1StartPoint =0.5,0> < GradientStop Color =GrayOffset =1/> < GradientStop Color =Green/> < / LinearGradientBrush> < /Rectangle.Fill> < / Rectangle> < ContentPresenter VerticalAlignment =CenterHorizo​​ntalAlignment =Center/> < / Grid> < / ControlTemplate> < /Window.Resources> <网格背景=黑色> < Viewport3D x：Name =viewMargin =0,0,0，-139ClipToBounds =FalseRenderOptions.EdgeMode =AliasedIsHitTestVisible =True> < Viewport3D.Camera> < PerspectiveCamera x：Name =cameraFieldOfView =60Position =0，-0.2,6LookDirection =0.000001，-0.0005，-0.08UpDirection =0,1,0> ; < PerspectiveCamera.Transform> < RotateTransform3D x：Name =rotCenterY =0CenterX =0CenterZ =0> < RotateTransform3D.Rotation> <！ -

为什么我有向前和向后轮换的麻烦？ 谢谢。解决方案 要旋转立方体（在我的示例中称为'cube'），但它可以是任何3D对象，使用中心点旋转很简单： // 这定义了中心点 - 一半通过所有3轴中的对象 Point3D centerPoint =新Point3D（ 2 。 5 ， 2 。 5 ， 2 。 5 ）; // 我想要旋转的角度。尚未指定哪个轴 int angleRot = 45 ; // 这里，在Vector3D中，用axis（x，y，z）指定应用角度 RotateTransForm myRotateTransform = New RotateTransform3D（New AxisAngleRotation3D（New Vector3D（ 0 ， 1 ， 0 ），angleRot），centerPoint）; // 应用转换 cube.Transform = myRotateTransform ; 当你想改变角度时，只需应用一个新的rotateTransform Hello everybody.In my application I have 3D cube.On cube sides I will place any controls.At the borders I have a buttons for rotate this cube to +-90 degree.But in fact I have rotate the camera, not cube.
