如何将程序生成的广告牌添加到 helix 3D
How to add a proceduaraly generated billboard to helix 3D
我有一组程序图像,我想将它们作为广告牌添加到我的 helix 3D 应用程序中。
目前我的应用程序如下所示:
public partial class _3DControl
{
HelixViewport3D hVp3D;
public _3DControl()
{
InitializeComponent();
createView();
}
public void createView()
{
hVp3D = new HelixViewport3D();
var lights = new SunLight();
lights.Altitude=40;
lights.Ambient=0.4;
this.Content = hVp3D;
hVp3D.Children.Add(lights);
this.Show();
}
public void UploadBillboard(BitmapImage im, System.Windows.Media.Media3D.Point3D position,double width,double height)
{
//create material
var mat = MaterialHelper.CreateImageMaterial(im, 0);
var bboard = new BillboardVisual3D();
bboard.Material = mat;
//set coordinates
bboard.Position = position;
bboard.Width = width;
bboard.Height = height;
//add the billboard
hVp3D.Children.Add(bboard);
}
但是当我调用添加广告牌的函数时:
HelixLinker.GetHelix().UploadBillboard(((Bitmap)e).bitmapToBitmapImage(),
new System.Windows.Media.Media3D.Point3D(0, 0, 0), 100, 100);
然后我发现没有添加任何内容,知道我哪里做错了吗?
我也尝试使用 RectangleVisual3D class。
public void UploadRect(BitmapImage im, System.Windows.Media.Media3D.Point3D position, double width, double height)
{
var mat = MaterialHelper.CreateImageMaterial(im, 0);
var bboard = new RectangleVisual3D ();
bboard.Material = mat;
bboard.Width = width;
hVp3D.Children.Add(bboard);
}
如果以相同的方式执行会产生(有前途的)图像 但是在这种情况下 material 似乎设置不正确。
注意:我希望 BillboardVisual3D 是正确的 class,我正在研究可以让我放置图像的东西 "on the floor" 可以这么说,我想要平面图像没有深度并允许透明度。
为什么将不透明度设置为 0?那你就什么都看不到了。
试试这个:
//create material
var mat = MaterialHelper.CreateImageMaterial(im);
编辑:
对不起,我的字符串不好。但这对我有用:
代码:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
CreateBilboard();
}
private void CreateBilboard()
{
BitmapImage im = new BitmapImage(new System.Uri(@"C:\Users\Public\Pictures\Sample Pictures\Lighthouse.jpg"));
var mat = MaterialHelper.CreateImageMaterial(im, 1);
var bboard = new BillboardVisual3D();
bboard.Material = mat;
var position = new System.Windows.Media.Media3D.Point3D(0, 0, 0);
var width = 100;
var height = 100;
//set coordinates
bboard.Position = position;
bboard.Width = width;
bboard.Height = height;
//add the billboard
viewPort.Children.Add(bboard);
}
}
XAML:
<Window x:Class="BillboardImageMaterialDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<ht:HelixViewport3D x:Name="viewPort" ZoomExtentsWhenLoaded="True">
<!-- Remember to add some lights -->

</ht:HelixViewport3D>
