Hi,
is there any chance to be able to register if the camera of the viewport is changed?

Greets,

Chris

HelixViewport3D.CameraChanged fires the right event.

public void AddRevolvedGeometry(IList<Point> points, Point3D origin, Vector3D direction, int thetaDiv)

Wishes everyon,

                   I loaded the .obj file into WPF visual c# application, now the issue is how to display the mesh generated by that .obj file using Helix tiilkit. Any help is appreciated.

Have a look at the examples on how to create a "HelixViewport3D" and add a .obj file model!
See Source\Examples\SimpleDemo and Source\Examples\ModelViewer and http://www.nudoq.org/#!/Packages/HelixToolkit/HelixToolkit.Wpf/ObjReader

Hi I am using the code behind with manipulators in my program with the following code:

        CubeVisual3D box = new CubeVisual3D();
        box.Center = new Point3D(x, y, z);
        CombinedManipulator boxManipulator = new CombinedManipulator();
        boxManipulator.Position = box.Center;
        boxManipulator.Pivot = box.Center;
        boxManipulator.CanRotateX = false;//true;
        boxManipulator.CanRotateY = false;// true;
        boxManipulator.CanRotateZ = false;// true;
        boxManipulator.CanTranslateX = false;// true;
        boxManipulator.CanTranslateY = false;// true;
        boxManipulator.CanTranslateZ = true;
        boxManipulator.Bind(box);
        vp.Children.Add(boxManipulator);
        vp.Children.Add(box);
        globalManipulatorList.Add(boxManipulator);

I can get the manipulator to work in the x and y and all rotation directions, however the Z translate direction does not show up on the viewport. I don't know why the other directions work but Z does not work.

The second question is what event can invoke when using a transparent bounding volume to detect a mouse left button down on the manipulator? I have been using the VisualTreeHelper.HitTest method to ignore transparent geometry before now but I don't know what method can be invoked once a manipulator is found by the VisualTreeHelper.HitTest method.

Thanks for the help,
Damian

1: Thanks for the notice - I see some change had broken the TranslateManipulator. I removed the default value of the Direction property, now it seems to work again.

2: Sorry, I don't quite understand the problem here. Please make an example that we can debug!

Hello everybody,

i have a little problem with adding manipulators to an visual via code, in my case a BoxVisual3D.

I define a box an two manipulators, one for moving, one for resizing:

var volumeBox = new BoxVisual3D();
volumeBox.Center = new Point3D(0, 0, 0);
volumeBox.Length = 0.3;
volumeBox.Width = 0.3;
volumeBox.Height = 0.3;
volumeBox.Material = MaterialHelper.CreateMaterial(Colors.SkyBlue, 0.3);

var xManipulator = new TranslateManipulator();
xManipulator.Color = Colors.Red;
xManipulator.Length = 0.4;
xManipulator.Diameter = 0.02;
xManipulator.Position = new Point3D(0, 0, 0);
xManipulator.Direction = new Vector3D(-1, 0, 0);
xManipulator.Offset = new Vector3D(-1, 0, 0);
xManipulator.Bind(volumeBox);

var xStretchManipulator = new TranslateManipulator();
xStretchManipulator.Color = Colors.SpringGreen;
xStretchManipulator.Length = 0.3;
xStretchManipulator.Diameter = 0.02;
xStretchManipulator.Position = new Point3D(0, 0, 0);
xStretchManipulator.Direction = new Vector3D(-1, 0, 0);
xStretchManipulator.Offset = new Vector3D(0, 0, 0);
//xStretchManipulator.Bind(volumeBox);

var binding = BindingOperations.SetBinding(
xStretchManipulator, TranslateManipulator.ValueProperty, new Binding("Length") { Source = volumeBox, Converter = new LinearConverter { M = 0.5 }});
binding.UpdateTarget();

//var targetBinding = BindingOperations.SetBinding(
//    xStretchManipulator, TranslateManipulator.TransformProperty, new Binding("Transform") { Source = volumeBox });
//targetBinding.UpdateTarget();
            
//var targetTransformBinding = BindingOperations.SetBinding(
//    xStretchManipulator, TranslateManipulator.TargetTransformProperty, new Binding("Transform") { Source = volumeBox });
//targetTransformBinding.UpdateTarget();

The code above works fine for resizing and moving the box, but the manipulator for resizing (xStretchManipulator) does not move with the box. When I add the transform-bindings to the xStretchManipulator, it moves with the box, but position is always in the center of the box and when you stretch to much, manipulator is inside the box.

Does anyone have an idea how to define and bind the manipulators, so that it works correctly?

Thanks a lot for any help or ideas!

Hello,

Where can I find this fork? I would like to take a look at it.

Also you will be able to make metro apps with this fork?

click: SOURCE CODE -> FORKS -> sharpdx
currently it is only WPF

Has anyone looked into the memory leak that is tripped by window resize events for the SharpDX build? With each resize several MB get lost.

Strangely the leak appears to accumulates on a TextBlock control.

I have forwarded this issue to the guys working on this fork!
