Hi,

I am drawing two points in the helixviewport3d using the following code. How can I offset/translate the points to new positions?

var result = new Point3DCollection(n);

var pt1 = new Point3D(0, 0, 0);
var pt2 = new Point3D(5, 5, 5);

result.Add(pt1);
result.Add(pt2);  

VisualPoints = new PointsVisual3D();
VisualPoints.Points = result;


myhelixviewport3d.Children.Add(VisualPoints);

Actually, I want to translate the two points to different locations. Applying translate transform to the VisualPoints would result in the translation of both the points to the same new location. Am I right in this?

Actually, I have about 300,000 points in "result" and I want to translate each point to a new position. I tried doing result[0].Offset(xnew,ynew,znew); but I found that the offset applies on a copy and not on the original point. So, other possible way is to replace all the points in "result" with new points (with new positions). Are there any other workarounds?

Hi.

I some circumstances the Geometry or TriangleIndices property on our models is null which causes the GetTotalNumberOfTriangles to throw an NullPointerException. Could you add some null checks or catch the exception?

Regards Dagfinn

added null checks - see 74458.

thanks for the feedback! good to hear that the zoomtofit function works for you!

stfx wrote at 2010-02-02 18:50:

Hey I just registered here to tell you how awesome that toolkit is. I use a modified version of it and it works perfectly. Do you have any progress on the code so far like object transformation (position, rotation, size) or maybe fit screen to object and fit to show all objects?

Please dont give up on it I really appreciate it.

Oh yeah you should consider to rename it to Helix Engine - sounds so much cooler :D

PS: I can send you the modifications if you are interested.

objo wrote at 2010-02-21 18:13:

Thanks for your feedback!! Sure, this project just started - I hope to get more work done on it soon. I have added you as a developer, you are welcome to submit improvements! There is a simple manipulator class for object transformation (translation only) in the toolkit now, but I am sure this needs more work. Do you have solutions to this? And the "fit screen to object" feature? That's a feature I would really like to have included!

Engine or toolkit - I like "toolkit" since this is mostly a collection of tools and helper classes - not replacing or encapsulating the wpf 3d engine.

Hallo, is it possible to add the TextBillboardVisual3D as ModelUIElement3D?

31337 wrote at 2012-11-30 12:22:

Figured it out myself.

"ContainerUIElement3D" is the answer.

Could you please elaborate on this a bit more? A code example would be nice. Thanks

Hi, 

First of all, great job, and thank you again. I'm a grateful user of Oxyplot, and here i find you again!

And now my question... have you any plans to give support to some CAD formats like .step, .sat,  or .iges?

objo wrote at 2011-12-19 09:24:

Sorry, no plans to implement readers for step, sat or iges. Only simple formats using triangular/quadrilateral meshes.

I might add import for a subset of the DXF format (polylines/curves and simple surfaces).

openNURBS is also interesting, would like to add a demo using the .net library:
