Hi all,
can anyone tell me how to display several colours (of my personal choice) within one TopoDS_Compound of BSplines, Surfaces and so on. So I want a very colourful graphic visualization.
Do I need the AIS_Shape class or anything else ?
Any hint is very welcome.
Best Regards

Hi,
do you have a code example ? Or would you advice the chapter about AIS_Shape ?

hi,
sorry to be so late...
this is the code :
Quantity_NameOfColor TabOfColor[Number_of_color];
TopExp_Explorer Ex;
int cpt = 0;
for (Ex.Init(mySolid, TopAbs_FACE); Ex.More(); Ex.Next())
{
TopoDS_Face F;
F = TopoDS::Face(Ex.Current());
Handle(AIS_Shape) aisUneForme = new AIS_Shape(F);
aisUneForme->SetColor(TabOfColor[cpt%Number_of_color]);
this->GetAISContext()->Display(aisUneForme);
cpt++;
}

Hi, thank you for your answer.
The code looks quite good, but maybe I was looking for somthing different:
Consider the tutorial (examples/tutorial) or the OCC-documentation.
There is this code "MakeBottle.cxx".
At the end of that program, any line/shape etc is being added to a TopoDS_Compound and returned to the OCC-viewer being implemented with the distribution.
How can I change the attributes of that lines/shapes their, so that I get a colourful picture ? How to choose the individual colour of any geometric entity within the TopoDS_Compound ?
Best Regards.
