如何在Helixtoolkit.SharpDX中加载STL文件？

<Window x:Class="YourNamespace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:h="http://helix-toolkit.org/wpf"
        Title="STL Viewer" Height="600" Width="800">
    <Grid>
        <h:HelixViewport3D x:Name="viewport">
            <!-- Add lights, camera, and other 3D objects here -->
        </h:HelixViewport3D>
    </Grid>
</Window>

using HelixToolkit.Wpf.SharpDX;

// ...

// 在适当的位置，加载STL文件
var stlModel = new STLModel3D();
stlModel.Load("path/to/your/stl/file.stl");

// 将STL模型添加到Viewport3D中
viewport.Children.Add(stlModel);
