When I try to zoom in (middle mouse wheel) using helix toolkit viewport it shudders, then refuses to zoom in. I can zoom out, but when I try to zoom back in it fails again. If I zoom out, go behind the model and then zoom in, it works sometimes, then I can go back around the front and zoom in.

Failed to paste example code.

In the helix Viewport overlay by default you have both the camera information and the coordinate system in the lower left corner.

I think you should move the camera information to the top left corner, and move the title to the top center, so that none of the overlays, overlap each other.

In Visual Studio 2017 when you select 3D object, some of the properties do not show up in the properties windows, especially transforms.

This means it makes it very difficult to do storyboard animations.

UWP and DirectX will work with Hololens.  Can Helix for UWP also work with Hololens?

It seems to be impossible to apply a LinearGradientBrush on a TubeVisual3D. Or is it?

I want to have a gradient along the tube, across all its segments and bends.

Any suggestions?

Hello,

I have many objects loaded in a scene (part of a SortingVisual3D) and added a manipulator to each of them. Everything works perfectly.

Now I want to surround them by a transparent cylinder. Also this works.

The problem I have now is that the manipulators are not useable when the objects are in the transparent cylinder because the mouse is captured by the cylinder.

Is there a way to make the box invisible for mouse operations?

I am using Helixtoolkit for C# WPF

I use the last version of Helix. When I try to open obj files through ModelViewer in Examples, the program crashes.

In previous version of Helix the same.obj files opens correctly.

Am I doing something wrong?
