如何旋转3D对象 [英] How to rotate 3D objects
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
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。

解决方案
我认为你应该做的是将你的所有立方体边包裹在一个新的ModelVisual3D中，如下所示：
< ModelVisual3D x：名称 = cube >
< Viewport2DVisual3D 材料 = {StaticResource CubeSideMaterial} >
您的多维数据集内容在这里...
< / Viewport2DVisual3D >
<！ - 立方体右侧 - >
< Viewport2DVisual3D 材料 = {StaticResource CubeSideMaterial} >
...此处...
< / Viewport2DVisual3D >
<！ - < span class =code-keyword> cube backside < span class =code-comment> - >
< Viewport2DVisual3D 材料 = {StaticResource CubeSideMaterial} >
...此处...
< / Viewport2DVisual3D >
<！ - 立方体左侧 - >
< Viewport2DVisual3D 材料 = {StaticResource CubeSideMaterial} >
......还在这里！
< / Viewport2DVisual3D >
< / ModelVisual3D >
请注意，我已将所有多维数据集内容完好无损并将其包装在内ModelVisual3D，通过命名该模型，您可以使用旋转变换的动画将它们全部旋转到一起：
私人 Rotation3D轮换;
private RotateTransform3D转换;
public Window1（）
{
InitializeComponent（）;
rotation = new AxisAngleRotation3D（ new Vector3D（ 0 ， 1 ， 0 ）， 0 ）;
transform = new RotateTransform3D（旋转）;
cube.Transform = transform;
}
私有 void SeeOthers_Click（ object sender，RoutedEventArgs e）
{
DoubleAnimation animation = new DoubleAnimation（ 90 ， new 持续时间（TimeSpan.FromSeconds（ 1 ）））;
rotation.BeginAnimation（AxisAngleRotation3D.AngleProperty，动画）;
}
在这个例子中，我只是将它旋转90度，但我想你可以搞清楚如何用其他角度调用它:)
希望这会有所帮助，

< blockquote>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. And I'd like to rotate exactly Cube.

Please help me, and one more.
Who know please advice - Why I have a troubles with rotation forward and backward?
Thanks.

What I think you should do is wrap all your cube sides in a newModelVisual3Dlike this:
<ModelVisual3D x:Name="cube"> <Viewport2DVisual3D Material="{StaticResource CubeSideMaterial}"> Your cube stuff goes here... </Viewport2DVisual3D> <!-- cube right side --> <Viewport2DVisual3D Material="{StaticResource CubeSideMaterial}"> ...and here... </Viewport2DVisual3D> <!-- cube back side --> <Viewport2DVisual3D Material="{StaticResource CubeSideMaterial}"> ...and here... </Viewport2DVisual3D> <!-- cube left side --> <Viewport2DVisual3D Material="{StaticResource CubeSideMaterial}"> ...and also here! </Viewport2DVisual3D> </ModelVisual3D>
Notice that I've left all your cube stuff intact and just wrapped them inside aModelVisual3D, and by naming that model you can rotate all of them together using an animation of a rotation transform:
private Rotation3D rotation; private RotateTransform3D transform; public Window1() { InitializeComponent(); rotation = new AxisAngleRotation3D(new Vector3D(0, 1, 0), 0); transform = new RotateTransform3D(rotation); cube.Transform = transform; } private void SeeOthers_Click(object sender, RoutedEventArgs e) { DoubleAnimation animation = new DoubleAnimation(90, new Duration(TimeSpan.FromSeconds(1))); rotation.BeginAnimation(AxisAngleRotation3D.AngleProperty, animation); }
In this example I'm just rotating it 90 degrees but I think you can figure out how to call that with other angles as well :)
Hope this helps,

To rotate a cube (in my example just called 'cube'), but it could be any 3D object, it is simple to rotate using the centre point:
//this defines the centre point - half-way thru the object in all 3 axis Point3D centerPoint = New Point3D(2.5, 2.5, 2.5); //the angle I want to rotate by. Not specified yet which axis int angleRot = 45; //Here, in the Vector3D, specify with axis (x, y, z) to apply the angle RotateTransForm myRotateTransform = New RotateTransform3D(New AxisAngleRotation3D(New Vector3D(0, 1, 0), angleRot), centerPoint); //apply the transform cube.Transform = myRotateTransform;
Just apply a new rotateTransform when you want to change angle
