Can helix toolkit be used with .NET 5.0? And which nuget SharpDX package should be used?
Hi,
I'm guessing helix toolkit can be used with .NET 5.0 because it works in my wpf project - but i did notice in the package tab it says "Package 'HelixToolkit.Wpf.2.17.0 " was restored using .NetFramework.Version=4.6.1, etc.""
I wasn't 100% sure which nuget package to use - the "HelixToolkit" or "HelixToolkit.Wpf".
And at the link https://github.com/helix-toolkit/helix-toolkit there are a list of sharpDX packages and wasn't sure whether to use HelixToolkit.SharpDX.wpf or HelixToolkit.SharpDx.core.
Thanks.

How can I draw many circles with SharpDX
Hi,
I want to draw many circles on the viewport.
Each circle should have a differnt color.
How can I do that.
I try it with the LineBuilder but then circle has many colors.
foreach (var _ in Lines.LineGeometry.Lines)
{
var color = GetNewColor(); //Ttis method just return a clolor
Lines.LineGeometry.Colors.Add(color);
Lines.LineGeometry.Colors.Add(color);
}
Any suggestions?
How can I zoom in and out in Helix with SharpDX with C#
I try to zoom in and out in the code behind.
<hx:Viewport3DX
Name="Viewport"
BackgroundColor="Black"
Camera="{Binding Camera}"
EffectsManager="{Binding EffectsManager}"
ShowViewCube="False">
</hx:Viewport3DX>
public OrthographicCamera Camera { get; }
public void ZoomIn()
{
var newPosition = new Point3D(Camera.Position.X, Camera.Position.Y, Camera.Position.Z * 1.5);
Camera.AnimateTo(newPosition, Camera.LookDirection, Camera.UpDirection, 500);
}
but nothing changed.
The Camera.Position.Z was changed but not the view of hte application.
Any suggestions?

Draw Triangle from "for cycles" iusse
I need to draw from code behind, (not from xaml), a large number of triangle. For calculation I calc half Triangleindices with a for cycle and the other half with another. Here the code : xaml:

myMeshGeometry3D.TriangleIndices.Add((j + punti) + i)
Next
Next
End Sub
End Class
My iusse is that only the triagles that are generate from the first cycle are showed, the second not. I tried to swap the cycle and they are both correct. I also tryed to add 2 button, one for cycle. they work to show half triangle, but only it first I clear the triangleindices.What am I missing? Any advice?
