c# – 如何在WPF中使用鼠标在ViewPort3D中旋转相机？

Animating the Position of a 3D Camera in WPF
(还有一个示例项目要尝试！)

Rotating the Camera with the Mouse

我同意XNA可能是3D情况的最佳解决方案,但原生3D支持和硬件加速渲染也是WPF和XAML的绝佳功能！

正如您所看到的,XAML Viewport3D的3D摄像头与应用程序完美匹配,也使用绑定：

<Viewport3D.Camera>
    <PerspectiveCamera x:Name="camera"
                       UpDirection="0,1"
                       LookDirection="{Binding RelativeSource={RelativeSource Self},Path=Position,Converter={StaticResource lookBackConverter}}"
                       Position="0,0" />
</Viewport3D.Camera>

…而且只是通常的IValueConverter实现让相机移动：

public class LookBackConverter : IValueConverter 
{
    public object Convert(object value,Type targetType,object parameter,System.Globalization.CultureInfo culture)
    {
        return new Point3D(0,0) - (Point3D)value;
    }

    public object ConvertBack(object value,System.Globalization.CultureInfo culture)
    {
        return null;
    }
}
