Hello.

I am trying to display triangles () on a created AIS Context and still cannot see the rendering unfortunately. here is how I implemented the Graphic3d_Group:

// Graphic 3D Environment Settings

StructMng = gcnew NCollection_Haft<Handle(Graphic3d_StructureManager)>(myAISContext()->MainPrsMgr()->StructureManager());

aPresentation = gcnew NCollection_Haft<Handle(Prs3d_Presentation)>(new Prs3d_Presentation(StructMng()));

aGroup = gcnew NCollection_Haft<Handle(Graphic3d_Group)>(Prs3d_Root::CurrentGroup(aPresentation())); 

Handle(Graphic3d_ArrayOfTriangles) myArray = ......;

.

.

.

.

aGroup()->AddPrimitiveArray(myArray);
