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

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...

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 9 years ago • updated 9 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

that should to it for the moment.
