Click Event not working anymore when using Helixtoolkit.SortingVisual3D

HI_ 11 years ago • updated 11 years ago • 0

I want to add transparency to Objects (without loosing the Click-Event). Google told me to try SortingVisual3D. Without SortingVisual3D everything (except transparency) worked well, Click-Events also.Now i tried to implement it (simplified code):

Public SV3d As New HelixToolkit.Wpf.SortingVisual3DPublic 
Model3DUI As New ModelUIElement3D

'Apply geometry
    Model3DUI.Model = geometry 'skipped geometry code in this post
'Add Click Event
    AddHandler Model3DUI.MouseLeftButtonUp, AddressOf ClickEvent
'Add to SortingVisual3D
    SV3d.Children.Add(Model3DUI)
'Add to ViewPort
    Viewport.Children.Add(SV3d)
'Setup SortingVisual3D
    SV3d.SortingFrequency = 2
    SV3d.Method = HelixToolkit.Wpf.SortingMethod.BoundingBoxCorners
    SV3d.IsSorting = True
Basically it works fine, everything renders as it should and transparency is working too. But for some reason now the Click Event doesn't work. Anybody has an idea what i'm doing wrong?

I'm not very experienced with Helixtoolkit, so it could be that my way is completely wrong.

First, A very good toolkit for Wpf.... just what I'm looking for. However, I wanted to learn more about Wpf 3d graphical UIs so I download the Helix source for this purpose. But upon building the project, I get a file error: Error 1 File 'Expressions\Plückers conoid.txt' cannot be found. in project: SurfaceDemo.

How such I workaround this error?

I need to know how zooming and moving by mouse scroll or mouse pan works.
I mean if i zoom with scroll in walkaround mode which parameter changes by this(FOV or CameraPoszition.z or cameratarget.z or ....)

Updating 153600 spheres (GeometryModel3D) to display kinect depth data in real-time

pyrrhicpk wrote at 2012-11-04 13:05:

Hi,

I am using Helix 3D toolkit to display kinect depth data, an attempt to display the point cloud in the helix viewport3d. For this, I am creating spheres for each point as a GeometryModel3D and update their positions in the depthframe ready event. However, this method only works for upto 150 points. A depth format of 320x240 corresponds to 153600 points, and updating the positions of 153600 spheres freezes up the UI. In the depthframe ready event, I am simply updating the positions using

 geometryPoints[i].Transform = new TranslateTransform3D(x[i], y[i], z[i]);

where geometryPoints is an array of 153600 GeometryModel3D and x, y, z are the depth data from the depth stream.

Any suggestions to avoid the UI freezing. Or simply its not possible to update this amount of sphere geometries in helix viewport 3d at 30fps?

Please advise.

Thanks

objo wrote at 2012-11-06 19:36:

That sounds like millions of triangles. I don't think you can update that fast on the ui thread, even if you just update the transforms of the Model3Ds...

see also http://msdn.microsoft.com/en-us/library/bb613553.aspx

pyrrhicpk wrote at 2012-11-08 09:37:

Is it possible to do this using PointsVisual3D instead of adding spheres? I can draw the whole point cloud using PointsVisual3D containing a list of all the points, but I dont know how to update the points. Any idea?

Thanks

How to store 3d models aspecially STL files in database?

Ardahan 11 years ago • updated 10 years ago • 5

I'am reading an STL file in my WPF c# application. I want to store it to database. All database connections are done but I don't know how to store 3d model in database. What kind of converting needed for this purpose? And later similarly I want to get that information from database to turn it 3d models.Is there any basic function for STL converting to binaries then merging it again?

Hello, I'm thinking of implementing 3D capabilities to my software. My aim is to include some modelling and simple animations. I've downloaded the examples and they are working really slow (slow rotations, zoom, etc; even with simple geometries) and my computer has VERY high specs. I don't understand why this is happening, is because of WPF or is a flaw of Helix?
Thanks.
P.D.: I wanted to use this library because I've used OxyPlot in the same application and it works marvelously.

Here is a video showing the lag. Is this normal or something is wrong?

a5r wrote at 2013-11-10 13:38:

For the car contour example I don't experience lag. In the video you posted I don't see too much problems either with the car contour example. In the second example, the background worker example I can confirm having more or less of the same lag (with my pc having lower specs compared to yours). But in the case of the background worker example my cpu usage is constantly 80 %. I guess this example does not exactly count for a simple geometry because it is constantly recreating countless ModelVisual3D objects. Is zooming and rotating also slow for the rest of the examples?

objo wrote at 2013-11-11 12:37:

I have not seen much lag in the contour example on my hardware (much lower specs than yours).
Are you rotating with touch or mouse gestures?
  1. Do you see this lag in other WPF3D applications? Try https://3dmoleculeviewer.codeplex.com/
  2. Have you tried to run the example applications outside Visual Studio?

Mouse Move Performance

I am trying to improve the speed of my viewport (containing around 100 models) and I cannot figure out why the processor spikes when I am moving the mouse over the viewport.
https://www.youtube.com/watch?v=QysWHudOvdQ

I would like to be able to add more 3D models to my viewport and I am looking for a way of reducing the CPU load. Is there some functionality which can be "sacrificed" to get better performance?

Thanks,
Blanka

govert wrote at 2014-01-17 13:15:

WPF might be doing hit-testing while you move the mouse. There is some way to disable this, and then only do hist testing when you need to, or on a timer. See: http://blogs.msdn.com/b/wpf3d/archive/2009/05/18/3d-hit-testing.aspx

I think I'm missing PepitaGet.Targets... where can I get it?

Thanks in advance!

objo wrote at 2013-04-18 09:45:

It seems like the build in the sharpdx fork is broken at the moment.
(I think there is a .. missing in the path for the pepitaget target. There may also be a problem with the weaving task target.)

przem321 wrote at 2013-04-25 23:26:

Yes, its broken, there are Pepita and Weaver missing in the right place. I can't push at the moment due to several re-factoring reasons. Just copy the folder

from

..\forks_objo_sharpdx_f924bc5e5a58\Tools\NotifyPropertyWeaver
..\forks_objo_sharpdx_f924bc5e5a58\Tools\NuGet
..\forks_objo_sharpdx_f924bc5e5a58\Tools\Pepita

to

..\forks_objo_sharpdx_f924bc5e5a58\Source\Tools\NuGet
..\forks_objo_sharpdx_f924bc5e5a58\Source\Tools\Pepita

that should to it for the moment.
