如何在WPF中使用鼠标(俯仰和偏航)和键盘旋转相机

问题描述

大家好，我目前正在Win7上使用地形和飞机的WPF游戏中.相机绑定在飞机上，我可以使用键盘WQSE向前，向左，向后和向右移动它.现在，我要使用键盘键"A"& 'D'和鼠标 旋转相机，以便我可以在环境中环顾四周，有人可以提供解决方案吗?有关如何设置音高和音量的教程详细地偏转或演示将非常好，因为我是C#的新手，我不想使用XNA.我知道如何用OpenGL制作 C ++，但实际上不知道如何在WPF中使用C#来实现. THX很多!!

Hi all, I'm currently working on a WPF game on Win7, with a terrain and an aircraft. The camera is bound to the aircraft and i can use keyboard WQSE to move it forward, left, back and right. Now I want to use keyboad 'A' & 'D' and mouse to rotate the camera so I can look around in the environment, anybody could give solutions? A tutorial of how to set pitch & yaw in detail or a demo would be very nice, cuz I'm new to C# and I don't want to use XNA. I know how to make it with OpenGL C++, but really don't know how to make it with C# in WPF. THX alot !!

推荐答案

根据您的描述，我同意XNA可能是3D情况的最佳解决方案，但是原生3D支持和硬件加速渲染也是WPF和XAML的绝佳功能.

According to your description, i agree that maybe XNA would be the best solution for 3D situations, but native 3D support and hardware-accelerated rendering are also fantastic features of WPF and XAML.

在第一个链接中，有一个示例项目，用于XAML Viewport3D的3D相机非常适合该应用程序，还使用了绑定:

In the first link, there is a sample project, a 3D camer for XAML Viewport3D fits perfectly with the aplication, also using bindings:

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

要让摄像机移动，只需实现IValueConverter:

To let the camera move, just implement the IValueConverter:

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

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