Other usage issues

Hello everyboby,

I have a profile (line and arc of circle) to display in V3d_Viewer, how can I do to display them with different colors?

Thanks for answer.

This is what i do to display the point in a bspline curve with a diferent colors:

Handle(TPrsStd_AISPresentation) prs;
Handle(AIS_InteractiveObject) aObject;
Handle(AIS_Drawer) aDrawer;
Handle(AIS_InteractiveContext) IC;
Handle(Prs3d_PointAspect) asp = new Prs3d_PointAspect(Aspect_TOM_O_POINT,Quantity_NOC_RED,1.0);
for(int k=1;k<=nPnt;k++)
{
prs= TPrsStd_AISPresentation::Set(L.FindChild(k+1), TNaming_NamedShape::GetID());
prs->Display(FALSE);
aObject = prs->GetAIS();
aDrawer =aObject->Attributes();
aDrawer->SetPointAspect(asp);
aObject->SetAttributes(aDrawer);
IC=aObject->GetContext();
IC->SetLocalAttributes(aObject,aDrawer,Standard_True);
prs->Display(TRUE);
}

I think you can adapt to your code.
I use the class Prs3d_PointAspect, in your case try to use the class Graphic3d_AspectLine3d.

Best regards
