Ho can I move all Manipulators adorner (by code C#) when for example I move X TranslatorManipulator? The code is working correctly because I can rotate and translate object, but adorners are fixed in the starting position.

My translator is

            translateManipulatorX.TargetTransform = mv.Content.Transform;
            translateManipulatorX.UnBind();
            translateManipulatorX.Bind(mv);
            translateManipulatorX.Length = Math.Max(mv.Content.Bounds.SizeX, Math.Max(mv.Content.Bounds.SizeY, mv.Content.Bounds.SizeZ)) * 1.2;
            translateManipulatorX.Offset = new Vector3D(mv.Content.Bounds.X + mv.Content.Bounds.SizeX, mv.Content.Bounds.Y + mv.Content.Bounds.SizeY / 2, mv.Content.Bounds.Z + mv.Content.Bounds.SizeZ / 2);
            translateManipulatorX.Visibility = System.Windows.Visibility.Visible;

If I remove offset all is working, but adorners are not correctly centered

Best regards

Hi there!
Thanks objo a lot for your great tools!

Doesn't anybody know what can be a problem for smoothing in Helix 3D Toolkit? I have a little bit strange case.. I got an .obj file with complex 3d-model which I want to be smooth. There are 2 "s on" lines in this file. I don't remember exactly but there was some issue while smoothng - and I set currentSmoothingGroup in ObjReader always to be 1.. And that helped, part of the 3d-object is now smooth. But only part.. For example I have a 3d-model of jaw - some teeth are smooth, some - very rough - there is clear difference. Using other 3d-viewers I can see all of the teeth are smooth.

In this file there are 2 "s on" lines - one before all vertices part, another one before faces. Plus there are a lot of separated "groups" (part of vertices or faces that start with "g"). I don't know maybe that is the problem - but groups with the same names are separated all over the file - ie that can be:
g Name1
...
g Name2
...
g Name1


I also tried to change some code in ObjReader - for example in AddGroup method in the beginning I put a line

if (Groups.Any(x => x.Name == name)) { return; }

And it partially helped - all teeth were smooth, but mesh in general was a little bit broken.. Than I changed smoothingGroupMap first parametr to be not int but the name of the group - for every group to have its own smoothing map (cause in original code after adding a group smoothing maps were destroyed) - but it made everything even worse. :(

Has anybody any ideas why there can be part of 3d-model smooth, and part of it - absolutely rough?

Does it look correct in other software? (try meshlab)
I guess there could be a bug in the obj importer. In that case we should have a small test file and create an issue on this!

Yes, exactly, I tried Meshlab :) And there when I switch on "Smooth" - it becames smooth, all of the teeth.

I can send you this .obj file..

This is how it looks:
Using HelixToolkit
Using MeshLab

I feel like there can be an issue with Groups...

By the way, this is what happened after inserting

 if (Groups.Any(x => x.Name == name)) { return; } 

line in AddGroup method:
After

Close enough, but appeared some clearly visible trouble with a few tens triangles on a problem part of the model...

And here is that .obj file - https://dl.dropboxusercontent.com/u/63365590/problematic_smoothing.obj

Thanks for providing the file! I have added the issue at https://helixtoolkit.codeplex.com/workitem/10067

I should be able to move and rotate the camera with the keyboard at least even while doing drag-drop operations, is there a way to retain that functionality?

Hello,

i am new to c# and WPF, and i am trying to use helix toolkit to represent a kinect depth image as a point cloud. i am trying to load Points3DCollection into PointsVisual3D as it is explained in the source for the pointsandlines example. It keeps returning the message that it cannot implicitly convert points3DCollection to pointsvisual3D. Is there an example just for creating point clouds or just points using the mentioned methods?

Thx

Hi,

I am also trying to create a point cloud for the human body using Kinect and Helix 3d. For now there is a sample in the examples directory which I think has some mistakes in converting depth to 3d mesh cordinates. I found this link useful :

Kinect Stackoverflow

using (DepthImageFrame depthFrame = e.OpenDepthImageFrame()) {
  DepthImagePixel[] depth = new DepthImagePixel[depthFrame.PixelDataLength];
  SkeletonPoint[] realPoints = new SkeletonPoint[depth.Length];

  depthFrame.CopyDepthImagePixelDataTo(depth);

  CoordinateMapper mapper = new CoordinateMapper(sensor);
  mapper.MapDepthFrameToSkeletonFrame(DEPTH_FORMAT, depth, realPoints);
}

If someone can help me with converting this cordinates into correct Point3d Cordinates :)

Luka1121, PointsVisual3D has a Points property to which you should assign your collection of points.

Abuseukk, you should probably decide to use the depth data as one of the coords of the points. new Point3D(xcoord, ycoord, depth[i]) would spread the points in Z axis accordingly to their depth.

this is my code.. i have to add HVP3D dynamically..

string[] AllFiles = Directory.GetFiles(@"C:\Users\..", "*.3ds");
            HelixViewport3D[] hel_ar = new HelixViewport3D[AllFiles.Count()];
            
            for (int i = 0; i < AllFiles.Count(); i++)
            {
                hel_ar[i] = new HelixViewport3D();

                PerspectiveCamera myPCamera = new PerspectiveCamera();
                myPCamera.Position = new Point3D(10000, 0, 0);
                myPCamera.LookDirection = new Vector3D(-1, 0, 0);
                myPCamera.FieldOfView = 60;
                hel_ar[i].Viewport.Camera = myPCamera;
               
                DirectionalLight myDirectionalLight = new DirectionalLight();
                myDirectionalLight.Color = Colors.White;
                myDirectionalLight.Direction = new Vector3D(-0.61, -0.5, -0.61);
                hel_ar[i].Viewport.Height = 115;
                hel_ar[i].Viewport.Width = 115;
                
                Model3DGroup m3d = new Model3DGroup();
                m3d = ModelImporter.Load(AllFiles[i]);
                m3d.Children.Add(myDirectionalLight);
                ModelVisual3D m = new ModelVisual3D();
                m.Content = m3d;
                hel_ar[i].Viewport.Children.Add(m);
               
                
               stackPanel1.Children.Add(hel_ar[i]);
                                
            }

I am trying to build a working example program to render Kinect data using the Helix SharpDX API and I need the correct steps for continually rendering a changing model. I have the old Kinect example from the WPF API working and I can generate a 3D model from the Kinect however all of the SharpDX examples use static models that are created in the MainViewModel constructors prior to rendering. Could someone provide the most efficient steps to continually rendering a changing model using the Helix SharpDX API?
