Disover upcoming cartoons, play mobile videos for free wherever you are, whenever you want. Download new and trending tubidy mp3 songs, search directly for tracks, artists and albums. Find new movies now playing in theaters, get movie times, watch trailers, browse tubidy videos and the hottest TV shows online.

3GP This video file type is made specifically with 3G smartphones in mind so that playback is the best it can possibly be. It also works on most 2G and 4G phones as well. The 3GP file type is available in either HD or Regular quality. Users can also choose to divide the file anywhere from 2-4 parts by choosing the 3GP Regular Parts options, or they can download 10 second previews in 3GP format to see if the file is what they want.

MP3 MP3 stands for MPEG-1 Audio Layer recorded in a compressed audio format and this format is given to the voices.

MP4 despite the similarity in each name, is not a continuation of MP3s. MP3 and MP4 formats are quite different from each other. MP3, MPEG-1 Audio Layer 3 stands for.

VideosThis video file type is notoriously difficult to play on smartphones, so computer users will get more use out of this one. Compared to Windows Media Player video files, the mp4 takes up significantly less space and is a favorite of users with video editing software, as mp4s are compatible with most programs.


Manipulator OnMouseDown event is not firing

Mike1955e 4 years ago in Defect? 0

I recently downloaded the latest code for the toolkit. I then tried out all of the demos and found that the manipulator demo does not work. All of the manipulators remain stationary. I placed a breakpoint at the OnMouseDown event and it was never reached. Can someone explain what I'm missing?

FEX: An example of some capabilities of Helix!

everytimer 5 years ago in Information updated by Wim Huyghe 5 years ago 8
Hello dear Helix mates!
I always loved Helix examples library: many examples and every one with something particularly interesting.
Last few months I've been developing a small but fairly complex application that is based on Helix Toolkit (WPF). If you are developing using this library you might be interested in seeing some of its features!

I have written a small article covering some highlights for Helix Toolkit users:

  • Custom design Orientation Cube
  • More ScreenSpaceVisual3D
  • Rotation around screen perpendicular axis
  • Improving performance by hiding mesh visuals
  • Several layers to enable hover visuals, selection and more
  • Transparency and sorting
  • Hit detection even not directly over the Visual

you can read it here:

PD. FEX is mainly for engineers who work with Finite Element Method models (in this case Nastran). I've attached an example for all of you in order to be able to experiment and play a little bit.

It would be awesome to hear back from you of what do you think of this!

AddExtrudedGeometry problem

MCv 2 years ago in Question 0

Hi Everyone,

I'm trying to create a simple 3d object, extruded one out of 4 pairs of 2D coordinates. But what I'm getting - is a 2d object. I can't understand: it's a my mistake or something else is wrong?

Here is my xaml code:

        <helix:HelixViewport3D x:Name="view1" Background="LightBlue" IsHeadLightEnabled="True" >

            <helix:MeshGeometryVisual3D  MeshGeometry="{Binding GlassGeometry}" Fill="White"/>

And code behind method:

  public MeshGeometry3D GlassGeometry
                var builder = new MeshBuilder(true, true);                 List<Point> pints2D = new List<Point>()
                    new Point(-1, -1),
                    new Point(0, -1),
                    new Point(1, 1),
                    new Point(-1, 1)
                Point3D sp = new Point3D(0, 0, 0);
                Point3D ep = new Point3D(0, 0, 1);

               builder.AddExtrudedGeometry(pints2D, new Vector3D(1,0, 0), sp, ep);

                return builder.ToMesh(true);

What I'm expecting to see is just a cube(in this case). But in the future I would like to get something like this:

But now my result looks like:

Or is it a possibility to create a 3d Object in code using 8 pairs of 3D coordinates?

Thank you in advance.


Selidbe - saveti, preselite se što lakše

Marko Nikolic 3 years ago in Information updated by anonymous 7 months ago 7

Put do preseljenja u novi dom prati dosta obaveza, organizacije, rada pa cesto kod vecine ljudi I dosta stresa I napora. Ako se svi potrebni radovi u novom stanu ili kuci zavrse na vreme od useljenja mozete napraviti cak I zabavnu akciju u kojoj ce naravno ucestvovati cela porodica.

Vratimo se na prvobitno stanje. Jos uvek ste u svom trenutnom zivotnom prostoru I predstoji Vam selidba. Najvise bi Vam odgovarao carobni stapic kojim biste se jednim potezom prebacili na novu destinaciju ali… Naoruzajte se voljom za rad I krenite I to prvo od onih stvari I predmeta koji Vam u ovom trenutku nisu potrebni. Kutija po kutija I Vi se polako oprastate od Vase dnevne, spavace sobe I ostalih starih prostorija za koje Vas veze gomila uspomena. Ako svaki spakovani paket, kutiju ili kesu obelezite odnosno napisete sta ste unutra spakovali to ce Vam znatno olaksati raspakivanje.

Nakon toga morate napraviti precizan plan o transportu svih pripremljenih paketa kao i namestaja, tehnike I sl. U eri kompjutera I interneta to je veoma jednostavno, jednim klikom po Vasoj tastaturi pronadjite ekipu koja ce selidbu obaviti u najkracem roku.

Ako ste sve pripremili, radnici firme selidbe beograd koja se na profesionalan nacin bavi svim vrstama selidbi moze biti ispred Vasih vrata. Nakon iznosenja I utovara, kamion sa Vasim stvarima moze da krene. Vama nista drugo ne preostaje vec da svoj dosadasnji dom zakljucate I krenete, I naravno sa sobom ponesete lepe uspomene iz njega.

Niste ni trepnuli a Vi ste vec u svom novom domu I vreme je za raspakovanje. Kako ne bi doslo do nereda I zbrke sada kada ste medju gomilom kutija I paketa najbolje je drzati se sistema koji ste pratili kao I kada ste se pakovali. Ponovo kutija po kutija, bez zurbe I napetosti I nove prostorije ce polako bivati opremljene. Posto niste u mogucnosti odmah da spremate obroke I kuhinju za tako kratko vreme osposobite za koriscenje, porucite nesto od hrane, spakujte decu u krevet I u miru provedite ostatak veceri.


Does Helix Toolkit work on UWP?

Garry Taylor 4 years ago 0

Hi everyone,

Just a quick question, does Helix Toolkit work on UWP? I've tried to build it, but lots of errors, so before I start looking into it further, is it even supposed to work?

Helix Toolkit has been amazing on WPF, just want to know if I can use on a UWP app?




Reference bugs in examples/source?

zangatsu 4 years ago in Question updated 4 years ago 0

Hi I just downloaded the newest source of the helix-toolkit. I wanted to get through all the examples to learn about the application, but unfortunately I get a lot of reference errors and I do not know why. I could solve most of them by reinstalling NuGetPackages and adjusting the fakes assemblies, however there are still a lot left. For example in MainViewModel:BaseViewModel class I get the reference error:

Error CS0246 The type or namespace name 'Camera' could not be found (are you missing a using directive or an assembly reference?) DemoCore _NET40 C:\..\helix-toolkit-master\Source\Examples\WPF.SharpDX\DemoCore\BaseViewModel.cs 29 Active.

This goes on with RenderTechnique, IEffectsManager and so on.

Do you have any solution? My references in DemoCore_NET40 all seem to work fine, at least I am getting no yellow symbol in the solution explorer...


Is there a way to create extruded 3d solid from planar polygon?

I am using HelixToolkit to create a simple city data visualization app. I need to extrude building plans from AutoCAD dwg file. ExtrudedVisual3D only result the side surface, without caps.

Rossie wrote at 2013-03-04 01:06:

Hi I had a similar requirement - but i had caps. The way I achieved it was to find the border edges of the polygon(s) and extrude them along the Z axis. But I implemented my own FindBorderEdges() method - because Helix3D's version did not entirely suit. Mainly because I wanted a contiguous list of edges - (Helix3D will put the output edges in the same sequence as the input edges - meaning that they may/may not be a contiguous list) I also wanted them in a particular winding order. I'll post my implementation - that might help you. (and perhaps the guys developing the Helix3D devs might want to use this code as well) I'll just paste in the main methods to do the work - i made a class called MeshGeometryHelper2. Let me know if i have missed anything - you might have to fiddle the source to fit your purpose.

How to use ExtrudedVisual3D to get a solid shape

jclu98 5 years ago in Question updated by anonymous 7 months ago 2

I was able to use ExtrudedVisual3D to get a extruded shape along a 3D path. But how do I make it solid? Right now, the extruded shape I got is hollow (means you can see through). How do I make it solid or at least add caps to both ends. I already spent many days on this but still could not figure out.
