在 WPF 应用中的 HelixViewport3D 中旋转对象
本文关键字:旋转 对象 HelixViewport3D 应用 WPF | 更新日期: 2024-11-06 13:15:48
我正在尝试使用 helixtoolkit 在 WPF 应用程序中显示一个 3d 对象,并根据 3 个变量(用户输入)沿 x,y,z 轴旋转它。但是我在螺旋工具包中找不到旋转 3d 对象的函数。
C# 代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Media.Media3D;
using HelixToolkit.Wpf;
namespace HelixTrial
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
ModelImporter importer = new ModelImporter();
Model3D model = importer.Load("D:''Crate1.obj");
Models.Content = model;
// need to apply rotation to the model using three x,y,z variables
}
}
}
XAML 代码
<Window x:Class="HelixTrial.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:HelixToolkit="clr-namespace:HelixToolkit.Wpf;assembly=HelixToolkit.Wpf"
Title="MainWindow" Height="500" Width="500">
<Grid Width="400" Height="400">
<HelixToolkit:HelixViewport3D x:Name="Viewport" ZoomExtentsWhenLoaded="True">
<HelixToolkit:SunLight/>
<ModelVisual3D x:Name="Models"/>
</HelixToolkit:HelixViewport3D>
</Grid>
</Window>
在工具包中找不到它,因为它是标准的 WPF 函数。所以在你的例子中,它看起来有点像这样:
<ModelVisual3D x:Name="Models">
<ModelVisual3D.Transform>
<Transform3DGroup>
<RotateTransform3D>
<RotateTransform3D.Rotation>
<AxisAngleRotation3D Axis="1,0,0" Angle="{Binding varX}"/>
</RotateTransform3D.Rotation>
</RotateTransform3D>
<RotateTransform3D>
<RotateTransform3D.Rotation>
<AxisAngleRotation3D Axis="0,1,0" Angle="{Binding varY}"/>
</RotateTransform3D.Rotation>
</RotateTransform3D>
<RotateTransform3D>
<RotateTransform3D.Rotation>
<AxisAngleRotation3D Axis="0,0,1" Angle="{Binding varZ}"/>
</RotateTransform3D.Rotation>
</RotateTransform3D>
</Transform3DGroup>
</ModelVisual3D.Transform>
</ModelVisual3D>
