Consistency with layout vectors

This discussion was imported from CodePlex

murray_b wrote at 2012-04-17 04:51:

Hi Objo

I have been using TextCreator and GridLinesVisual3D and noticed a little inconsistency

The layout of these both use two vectors to define the layout.

Ie  GridlinesVisual3D uses : Normal, LengthDirection

TextCreator uses: Over, Up

Essentially the same thing

If you use the same vectors with these they are drawn at 90 degrees to each other.

Do you think they should orientate the same?

Just a thought

Regards

Murray


objo wrote at 2012-04-17 08:02:

Good point, I want the api to be as consistent as possible. I will see if I can improve it. I guess you want to define the normal of the text face? 


murray_b wrote at 2012-04-17 08:08:

Yes that sounds good.   Normal, HeighDirection ? maybe, would seem consistent.

What ever you think is best. 

I just noticed this because i was using a grid and text together and found it strange that I had to use two different sets of vectors to get them to line up.

Thanks

Murray

Cutting a mesh with a plane of limited size?

Mehran Maghoumi 10 years ago 0
I know that MeshGeometryHelper has the Cut method that can cut a mesh against a plane.
Obviously, that function uses the traditional math definition of a plane (a plane which has an infinite size).
Is there an easy way to adapt that method to perform a cut using a plane of limited size? In other words, let's say we have the point and the normal of the plane as well as its width and height. How could we cut only a part of the mesh that intersects with this "limited" plane?
Is there a straightforward way of doing this?

I have 2 circle with different radius and direction, and I need to animate the process 1 circle transform to other and create a shape along the way (like extrude surface but have scale and rotate as well). Anyone has idea or suggestion code to achieve this? Thank in advance

Best regards,

AnaglyphView3D ModelUpDirection

Anonymous 11 years ago 0
This discussion was imported from CodePlex

thecake wrote at 2012-10-12 13:46:

The HelixViewport3D has a ModelUpDirection property, which affects the turning directions of the Camera - the anaglyph view does not have this property.

How can I change the ModelUpDirection of the anaglyph view, that it corresponds with the Cameras UpDirection?

thanks!


objo wrote at 2012-10-14 16:00:

It should be possible to bind the ModelUpDirection of the CameraController inside the AnaglyphView. I added the issue http://helixtoolkit.codeplex.com/workitem/9970

Experts,

I have tried over the past few weeks to get the Flights Demo (in VB) debugged, but even after writing to @objo privately and other posts here, I have no responses. That's fine... I understand it is only important to me.

So I went to Freelancers.com and posted a project there, with a $50 USD bounty. I don't want anyone here to think I am asking for their time without compensation. Volunteering and helping for free only go so far-I get it. So I am willing to get the help on your terms, by showing my appreciation with cash.

If you are interested, you can see the project here on freelancer.com...

I will choose a winning bidder in the next few hours.

Thanks, everyone!

MODERATORS: This is not a generic solicitation or advertisement. It is a problem specific to my implementing this CodePlex project (Helix 3D Toolkit), and is represented as such on both sites. In addition, this is the first time I've let the community know about opportunities to help for $.

objo wrote at 2014-08-08 12:46:

No problem, I hope you found someone that could solve the problem! I am interested to know how it went - was the problem solved? Sorry, I have very limited free time and cannot involve myself in all discussions at the moment.

Calling overridable method in the constructor ?

Anonymous 11 years ago 0
This discussion was imported from CodePlex

SagarDabas wrote at 2013-03-31 08:05:

I am doing little changes in QuadVisual3D by overriding Tessellate. AreaChart is the subclass of QuadVisual3D.
public static readonly DependencyProperty PointsProperty = 
DependencyProperty.Register("PointsList", typeof(Point3DCollection), 
typeof(AreaChart), new UIPropertyMetadata(null,
 GeometryChanged));


 public Point3DCollection PointsList
    {
        get
        { return (Point3DCollection)this.GetValue(PointsProperty); }

        set
        { this.SetValue(PointsProperty, value); }
    }
I am not able to instantiate PointsList property using this code :
<local:AreaChart PointsList="0,0,8 0,-10,11" Extrusion="2" />
I am getting Count as 0 (or null Exception if I don't give a default value in the PropertyMetadata).

It looks like Tessellate method is invoked in the constructor of MeshElement3D class.
Can you please suggest what should I do ?

SagarDabas wrote at 2013-03-31 09:35:

Ok, Got it. I used a temporary list to do the changes rather than directly modifying the property.
And initialized property with default values which is changed when the AreaChart constructor is invoked or it's fields are initialized.

Thanks for the awesome library.

When I open the ExampleBrowser project. in VS 2012 Express I get the warning "The referenced component 'HelixToolkit.Wpf.Input' could not be found.

When I buid the project I also get the following error:

Error 1 The "PepitaGet.RestorePackagesTask" task could not be loaded from the assembly C:\Users\Brad\Documents\Visual Studio 2012\Helixtoolkit\Source\Examples\ExampleBrowser..\Tools\Pepita\PepitaGet.dll. Could not load file or assembly 'file:///C:\Users\Brad\Documents\Visual Studio 2012\Helixtoolkit\Source\Examples\Tools\Pepita\PepitaGet.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

Any idea as to how I resolve this.

Is this in the SharpDX fork? The default fork should not have this problem. The PepitaGet.dll should be in ~\Tools\Pepita

I would like to move this project to GitHub.
  • better issue tracker
  • better handling of pull requests
  • github pages
  • integration with appveyor

Rogad wrote at 2014-08-26 17:45:

Would you be able to keep the topics here ? It's just I have some bookmarked for reference...

BogusException wrote at 2014-08-26 19:39:

@Rogad,

Github is SCM, like Subversion... :)

Go check the site out...

Rogad wrote at 2014-08-26 20:44:

Yeah I now Github, I just was worried all the discussions will be lost...

objo wrote at 2014-08-27 08:37:

I think Stack Overflow can be used for questions on how to use the library: http://stackoverflow.com/questions/tagged/helix-3d-toolkit
The GitHub issues section can be used for discussions regarding bugs and new features.

objo wrote at 2014-08-27 23:38:

Yee-haw, here we go! :-)
The worst is that I am planning to do this with all the CodePlex projects I am coordinating...
I have been a happy resident at CodePlex for a while now, but suddenly I figured out that GitHub gives the project a lot of new possibilities...
My only concern is the discussion forum and all the unanswered threads here... But they should still be reachable from the search engines....

BogusException wrote at 2014-08-28 18:04:

I'll bet if you ask, they've probably had someone write a perl script or some such to migrate message archives from places like CodePlex... If they have an API they can share, then it would not be hard to create one...

I'd be really surprised if it hadn't been done already...

I just hope the text editor is better than CodePlex's... That was an area they never fixed... :(



objo wrote at 2014-09-01 07:42:

Yes, it is possible to migrate the messages to a new forum, but I think Stack Overflow is a good alternative since it is already used for Helix Toolkit questions.
I am concerned about distributing the project over too many sites. You see the list at the bottom of the readme file is already quite long...
