How to retrieve the color of a point (in a BRep model)

How to retrieve the color of a point (in a BRep model)

1. Get the ModelData_BRepRepresentation of a part;
2. Get a list of all the Bodies that belong to this Part: ModelData_BodyList aBodyList = theBRep.Get();
3. Use Appearance(aBody) method of the ModelData_BRepRepresentation object to retrieve appearance of the Body;
4. Use ToColor method of the ModelData_Appearance object to get the color.

Here's an example of code for a viewer:
  1. class PartBRepVisitor : ModelData_Model.VoidElementVisitor
  2. {
  3.     public PartBRepVisitor()
  4.     {
  5.     }

  7.     public override void Apply(ModelData_Part thePart)
  8.     {
  9.         ModelData_BRepRepresentation aBRep = thePart.BRepRepresentation();
  10.         if (aBRep != null)
  11.         {
  12.             ExploreBRep(aBRep);
  13.         }
  14.     }

  16.     private void ExploreBRep(ModelData_BRepRepresentation theBRep)
  17.     {
  18.         ModelData_BodyList aBodyList = theBRep.Get();
  19.         for (uint i = 0; i < aBodyList.Size(); ++i)
  20.         {
  21.             ModelData_Body aBody = aBodyList.Access(i);
  22.             if (aBody.BodyType() == ModelData_BodyType.ModelData_BT_Acorn)
  23.             {
  24.                 ModelData_Appearance anApperance = theBRep.Appearance(aBody);
  25.                 ModelData_Color aColor = new ModelData_Color();
  26.                 anApperance.ToColor(aColor);
  27.                 Console.WriteLine(aColor.R());
  28.                 Console.WriteLine(aColor.G());
  29.                 Console.WriteLine(aColor.B());
  30.             }
  31.         }
  32.     }
  33. }
