Firstly, thank you for the great work.

My question relates to the behavior of the keyboard panning (shift-arrows).

Clicking left causes the camera to move to the right (model moves to the left).  I realize this is is just a difference in perspective, however feedback I have received indicates that this is counter-intuitive to them.  These folk are video game players in which the more common pan would yield the camera moving in the same direction.

Would it be possible to have an inversion property added?  I investigated stealing keyboard events or overriding gestures, but the camera controller is attaching itself to the keydown event directly.  The only option I found is to disable panning, however I still need panning to occur via addPanForce (which I invoke directly from an onscreen controller I created).

Thanks.

objo wrote at 2012-04-26 23:07:

I added a LeftRightRotationSensitivity property. Try to set this to -1 to invert the keys. 

Tungsten wrote at 2012-04-27 00:17:

Thank you for the quick response.

The LeftRightPanSensitivity and UpDownPanSensivity are exactly what I need, however did you intend to not add the template bindings for all 5 new sensitivity properties (the 2 rotations were added).   I am applying the properties to the CameraController directly for now.

objo wrote at 2012-04-27 06:48:

Of course, I had forgotten the 3 last ones. Thank you, fix submitted.

Hi,

how can i rotate the camera in per code?

i can't find any methods for that in CameraController.

(or schould i use wpf's RotateTransform3D)

objo wrote at 2011-12-13 18:46:

you can use the "AddRotateForce" method - that's what the keyboard bindings are using.

If you need more custom rotations, I suggest you create a Quaternion and do the rotations on the LookDirection and Camera Position.

You find the camera rotation transformations in the RotateHandler class.

why do I have this error when opening XAML designer in any example project, or creating my own (adding reference manually or with Nuget, doesn't matter)?

In editor IntelliSense 'knows'  namespace HelixToolkit but don't know anything inside it

Beside this, project compiles and runs

VS2010, .Net 4.0

mannest wrote at 2013-01-25 06:47:

I have same problem.

Did you build HelixToolkit.Wpf_NET40 project in x64 platform?

In my case, no problem in x86 platform built.

Anyway, I don't know how to solve that problem in x64 platform.

Noylene wrote at 2013-01-25 07:07:

No, it's x86, WinXP

JohnSourcer wrote at 2013-01-25 07:10:

It's a known problem and doesn't affect the build. There are several reports of this and workarounds/solutions. Most common seems to be issues with 64 bit vs 32 bit builds and dll's.

Hi,

I am using the following code to draw a sphere in HelixViewport3D. Now I want to create a 3D line between two spheres. Any suggestions please.

Thanks

var meshBuilder = new MeshBuilder(false, false);
meshBuilder.AddSphere(new Point3D(0, 0, 0), 0.1f, 10, 10);
var mesh = meshBuilder.ToMesh(true);
modelGroup = new Model3DGroup();
var greenMaterial = MaterialHelper.CreateMaterial(Colors.Green);
var insideMaterial = MaterialHelper.CreateMaterial(Colors.Yellow);

            mygeometry = new GeometryModel3D();
            mygeometry.Material = greenMaterial;
            mygeometry.BackMaterial = insideMaterial;
            mygeometry.Geometry = mesh;

           modelGroup.Children.Add(mygeometry);    

           myModelVisual3D = new ModelVisual3D();
           myModelVisual3D.Content = modelGroup;

           myview.Children.Clear();
           myview.Children.Add(myModelVisual3D);

objo wrote at 2012-10-16 15:36:

use a cylinder? See MeshBuilder.AddCylinder

To draw a line, try LinesVisual3D.
