I need to implement the following approach in my application - load IGES file, get tessellation and some other data for every element:
- vertices and faces,
- lines,
- circles,
- object name,
- object color.
How to get the coordinate value of each graphic element? For example, the start and end coordinates of a straight line, the radius of a circle, etc.
The official demo source code is too simple, and there is no introduction in this regard.Could you please give me some hints how to get it?
#include “IGESControl_Reader.hxx”
#include “TColStd_HSequenceOfTransient.hxx”
#include “TopoDS_Shape.hxx”
{
IGESControl_Reader myIgesReader;
Standard_Integer nIgesFaces,nTransFaces;
myIgesReader.ReadFile (“MyFile.igs”);
//loads file MyFile.igs
Handle(TColStd_HSequenceOfTransient) myList = myIgesReader.GiveList(“iges-faces”);
//selects all IGES faces in the file and puts them into a list called //MyList,
nIgesFaces = myList-Length();
nTransFaces = myIgesReader.TransferList(myList);
//translates MyList,
cout<<"IGES Faces: "<<nIgesFaces<<" Transferred:"<<nTransFaces<<endl;
TopoDS_Shape sh = myIgesReader.OneShape();
//and obtains the results in an OCCT shape.
}
