Hi,

I am making a simple rotation and translation of 3d object in windows phone 8 . Can i make use of kit3d library to work in it?

Thankyou

New Post: Transformation of sreen coordinated to model coordinates in Silverlight using Kit3D

dushyant1000 — Tue, 25 Jan 2011 13:30:05 GMT

agreed, I got the mesh. now I need to update mesh.positions by some value, (which is going to be the EndPt.X-startPat.X, similar for Y and Z), So I need to know the startPt and endpt w.r.t to model.

How to get startPt and endPt?

Below is the sample code for the condition I am talking

            Point3D pt1 = new Point3D(0, 0, 0);
            Point3D pt2 = new Point3D(0.5, 0, 0);
            Point3D pt3 = new Point3D(0, 0.5, 0);
            mesh.Positions.Add(pt1);
            mesh.Positions.Add(pt2);
            mesh.Positions.Add(pt3);
            mesh.TriangleIndices.Add(0);
            mesh.TriangleIndices.Add(1);
            mesh.TriangleIndices.Add(2);

suppose I am clicking mouse at the 2nd vertex (0.5, 0, 0), so my start point should be Point3D(0.5, 0, 0). How to get it?

Regards

On MouseLeftButtonDown event,

// The point in screen
Point3D testPoint3D = new Point3D((float)currMousePos.X, (float)currMousePos.Y, 0);

// the orientation vector
Vector3D testDirection3D = new Vector3D((float)currMousePos.X, (float)currMousePos.Y, 10);

// pt and vec params
PointHitTestParams pointparams = new PointHitTestParams(currMousePos);

Kit3D.Windows.Media.VisualTreeHelper.HitTest(viewport3d, null, HTResult, pointparams);


The 3rd parameter of HitTest is a callback function with prototype: HitTestResultBehavior HTResult(HitTestResult res);
So
public HitTestResultBehavior HTResult(HitTestResult res)
{
    RayHitTestResult rayResult = res as RayHitTestResult;
    
    if(rayResult != null)
    {
        RayMeshGeometry3DHitTestResult rayMeshResult = rayResult as RayMeshGeometry3DHitTestResult;
        
        if(rayMeshResult != null)
        {
             hitgeometry = rayMeshResult.ModelHit as GeometryModel3D; // global GeometryModel3D var
             hitmesh = rayMeshResult.MeshHit as MeshGeometry3D; // global MeshGeometry3D var

             // whatever logic you want to hitted model
        }
    }

}

I am trying to implement drag and drop functionality in Silverlight using kit3d. I need to change triangle's vertex coordinates when mouse is released. For this I need to convert screen coordinates into model coordinates. Reverse in there in kit3d. Can anyone help me with sample code to do the same?
Please note "HitTest" does not transform to model coordinates, you can see the ModelVisual3D.cs for the way model to screen transformation is done.

Thanks in advance.

why dont you just upload the source to the patches section?

New Post: Opacity with ImageBrush

jburchel — Tue, 23 Nov 2010 05:58:23 GMT

I didn't see any Opacity property on the DiffuseMaterial or Material objects. I could set Opacity on the ModelVisual3D though! :) I think that may work then... We'll see...

javpnunes — Mon, 22 Nov 2010 10:19:19 GMT

Hello,

Your code looks fine, maybe this is not possible yet in kit3d. Have you tried to set the material opacity directly?

regards

Hi,

Thanks for the efforts on this!

I am trying to set Opacity on an ImageBrush for use with a Kit3DBrush, however, not seeing any transparency on my object. Is Opacity property of the ImageBrush supported? Maybe not, but hopefully so. I am using it in the same way I used it in WPF so I think I used it correctly:

            ImageBrush mapBrush = new ImageBrush();
            mapBrush.ImageSource = new BitmapImage(new Uri(@"images\EarthMap10k.jpg", UriKind.Relative));
            mapBrush.Opacity = .2;
            Kit3DBrush kit3dMapBrush = new Kit3DBrush(mapBrush, 600, 400);
            DiffuseMaterial mapMat = new DiffuseMaterial(kit3dMapBrush);

            geomod.Material = mapMat; //new DiffuseMaterial(new Kit3DBrush(new SolidColorBrush(Colors.Blue)));
            geomod.BackMaterial = mapMat;

In WPF this same approach allows me to display a partially transparent globe so I can see the back side of the globe through the sphere.

Thank you, and hope to see more soon! The Viewport2DVisual3D would be awesome!

New Post: How it works?

tharnadar — Wed, 27 Oct 2010 15:10:29 GMT

Hi all, i've seen this project and it's very powerful.

But i've noticed the lack of documentation, there's nothing that explain how it works, but only how to use it.

Would be nice to use some class diagram, sequence diagram, other papers, etc..

Anything about it?

Thank you for replies

kittykittyraw — Thu, 07 Oct 2010 22:32:55 GMT

Can Kit3D import any sort of 3D file (.mb, .obj, .3ds, .dxf, .max, .xaml, etc)? I would like to use several 3D files, converting is no problem. I heard something about .3DS files being able to be used.

Do I have to credit Kit3D when I use it in a project?

In Kit3d, is there any way to add the ViewPort3D in the Canvas insted of Grid. In this application the ViewPort3D calss added in the Gird (Refer to RotatingCubes.xaml). I have tried to add the existing Grid in the Canvas, however adding grid in the canvas does not dispaly anything on the screen.

Here is the problem I have met with porting Petzold's cylinder to silverlight.

I draw two cylinders at different position, but they both mess together.

The version of the silverlight.net has the lighting information in it. You can download it here: http://sildev.net/pub/3DMonkey.zip

Hi all!

I've developed a deformable mesh by using Kit3D.

You can check it on http://www.raonalab.com/silverlightme, under the Real3D Tab.

Hope you like it!
