Other usage issues

I want to draw many lines with different color,here is my way:
Handle(AIS_Line) anAISLine = new AIS_Line(&PntStart,&PntEnd);
anAISLine->SetColor(mycolor);
myAISContext->Display(anAISLine);
But for every line I have to use these same code, it is very slow to display all lines once,what can I do? Maybe use AIS_Line array ,just as TopTools_Array1OfShape ? And I don't know how to color the TopoDS_Shape ,otherwise I will use TopoDS_Shape instead of the AIS_Line ?

Hi seumonkeu,

try this:

for(...)
{
anAISLine->SetColor(mycolor);
myAISContext->Display(anAISLine, Standard_False);
}

myAISContext->UpdateCurrentViewer();

This should help.
