How do i get the coordinates (x,y,z) of each vertex?

Hi,

I need to get, for each element of ifc model, the cartesian coordinates (x, y, z) of each vertex. I tried to use the BoundingBoxes but does not to my case.

Thanks

hi,

i guess you're supposed to use context.ShapeGeometryMeshOf(XbimShapeGeometry); But this method seams not working yet.

If you look at windowsUI : Xbim.Presentation.MeshGeometry3DExtensions you'll found a set of read() methods which is similar to ShapeGeometryMeshOf(). Maybe you could use a similar code for now until the method works.

you'll get output like :

• Normals Count = 24 System.Collections.Generic.IEnumerable {System.Collections.Generic.List}
• Positions Count = 24 System.Collections.Generic.IEnumerable {System.Collections.Generic.List}
• TriangleIndices Count = 36 System.Collections.Generic.IList {System.Collections.Generic.List}

which contains the cartesian coordinates of the corresponding vertex attributes

good luck

You can work with geometry directly, rather than the mesh of the geometry. This gives you full access to the BREP of the shape, i.e. all vertices, edges, faces, shells and solids. Look in the geometry Test cases in the Xbim.Geometry engine to see how to do this.

@PierreAlexandreADAMSKI

could you share the piece of code that you were successful with using Xbim.Presentation.MeshGeometry3DExtensions.read()?

I wasnt able to figure out what I have to pass for the "m3d" in public static void Read(this MeshGeometry3D m3D, byte[] mesh, XbimMatrix3D? transform = null)

Please, I need this to get my project going ahead.

Also, if you cloud suggest a way to get the triangulated mesh of from a polyhedronbinary , it will be great.

Many thanks in advance, Ani

If I remember, MeshGeometry3D can be found in the context of your scene. Be careful with WindowsUI since some objects are covered to WindowsUI specific objects.

Then I remember playing with the read () functions to improve the cemetery as I needed it so since it was 6 months ago I'd have to check out more in details tomorrow for some memory refresh.

Try looking at the test cases they are very helpful to understand the code better.

For the polyhedron I think it's working just fine with the read method

Pierre,

Thanks for the information. I'll wait to hear from you if you find any further information on this. Thank you again, Anirudh
