I'm new with helix-toolkit, and I'm trying to do an interface with a 3D representation of a point cloud
Lunci
@holance
@david33-a11 Use HelixToolkit SharpDX version with PointGeometryModel3D to render point cloud.

okay, thanks
and do you know any tutorial?

hello, how do i know bounds of volumeTextureModel3D?
created the volume model using: volModel = new VolumeTextureModel3D();
DeshpandeJanhavi
@DeshpandeJanhavi
volModel.VolumeMaterial = volMaterial

Hi All - I am using Helix Viewport3DX. I am using the EnvironmentMap3D property to specify an environment which my model can use to reflect the environment. But I want the background behind the model to be transparent. Is this possible?
Lunci
@holance
@DeshpandeJanhavi Volume bound is always 1x1x1 cube
@aronbardsley Environment map is a static image. Not sure why you want to reflect environment but not rendering the environment map.

Hi guys, there are some built in tool for draw a curved pipe by specified angle?
Like something in right side

Hi, I add a ModelVisual3D to my Helix Viewport3D, and this ModelVisual3D contains some model3Ds. But when I change the transform of these model3Ds, the final ModelVisual3D doesn't change. Is there any steps that can refresh the ModelVisual3D ?

Hello, I'm using Helix SharpDX to display a collection of PointGeometryModel3D. I am attempting to use the built in "MouseDown3D="HelixView_MouseDown3D" to do hit testing, and can't seem to be able to select points. This approach works well for MeshGeometryModel3D and LineGeometryModel3D. Any advice?
Dimoniums
@Dimoniums
helix-toolkit/helix-toolkit#1416 Seems this issue existed before, but I don't see that it was corrected.
Lunci
@holance
@Dimoniums How many points in each of the PointGeometryModel3D in your case?
The issue only happens when there is only one point in PointGeometryModel3D.
Dimoniums
@Dimoniums

All points are in one ObservableCollection which is added to the view through a template

<DataTemplate x:Key="Point3DTemplate">
<hx:PointGeometryModel3D Geometry="{Binding Geometry}" Color="{Binding Color}" Size="{Binding Size}" Tag="{Binding Tag}" IsHitTestVisible="{Binding IsHitTestVisible}" FixedSize="True"/>
</DataTemplate>
<hx:ItemsModel3D ItemTemplate="{StaticResource Point3DTemplate}" ItemsSource="{Binding HelixPoints}"/>

Wait, If i understand correctly. When adding points to the list there should only be 1 point object which holds all point positions?
Lunci
@holance
@Dimoniums It's prefer to aggregate points into few point models for performance reason. It is better for gpu to just draw a lot of points in one pass than to draw points one at a time.
Dimoniums
@Dimoniums
I was doing one at a time to take advantage of the .Tag property. That way I can use hit test to find related data object. Now using .Indecies for same purpose. Hit test working.

Hi everyone, I have a list of double[] representing points for some calculation. for now i'm adding points into the view by creating a point with corresponding coordinate and updating the geometry.
Now i need to remove some of theses points [using sharpDX]. Is there a way to link my double[] list to points of the geometry so when i remove a double[] from the list, it'll be removed from the geometry (and the view) ?

For now, when i have a point to remove, i'm iterating though all the geometry to find the corresponding point, and i feel like it's an uggly way to do.
Thank you

Lunci
@holance
@Titibo26 I believe you should only use single geometry to represents all the points. After updating your list of double[], simply re-generate the point geometry and assign to the point model.
Or you can generate Vector3Collection from your own library directly without going through generating the double list.

some parts are disappearing on zooming out.
e.g. Here the tyre is gone.

When did you plan to make a V2.16.0 Release?

@holance
@heyufei2008 Increase the camera far plane distance to avoid model disappearing.
Remove the post effect in xaml to remove the yellow lines.
@gregorsGit Maybe this weekend or next weekend.

Hey guys , could you tell me how to show System.Windows.Media.Media3D.GeometryModel3D element in Wpf.SharpDX viewport3DX , because using <ModelVisual3D> turned out to be failed
Lunci
@holance
@USTC-Wang You can't use wpf 3d elements in sharpdx version.

Hi guys, how can I bind two gestures to Pan operation?
<MouseBinding Command="hx:ViewportCommands.Pan" Gesture="LeftClick + RightClick" /> It's not work! How can do this?

Is it still possible to add .obj file into wpf for viewing in 3d
?

@jackal-zilla the example projects in the source code had some examples of importing model files

@Gravemind2401
in sharpdx wpf is it possible to create Element3D objects asynchronously?
i tried putting my mesh loading code inside await Dispatcher.InvokeAsync(LoadFunction) and everything seems fine in the code (and no thread ownership errors) but none of the elements are visible in the viewport
the same LoadFunction() works just fine synchronously
but of course it freezes the ui
Lunci
@holance
@Gravemind2401 You can't create element3d from another thread other than UI thread (wpf limitation). You can create scene nodes from another thread, but needs to use UI thread to attach to the viewport.
Gravemind2401
@Gravemind2401
im using Dispatcher.InvokeAsync so the elements are being created on the UI thread, they just dont seem to render at all
