ask for a lite version of AIS_Line

Forums: 

Hi,

We all know create 1000 manginude AIS_Line will cause serious performance problem. Of course we can collect them into a TopoDS_Compound, then use only one AIS_Shape to display it.

But this is just a workaround. In fact, it is unnecessary to add a topology relation on them in general application context. So is there a lite version available? it can be pick and display easily and effeciently. or how can we implement such a stuff?

best regards,
fhchina

My 2 cents :
if you want a powerfull but slow display, use the OpenCASCADE display.
if you want fast display : use OpenGL

if you are a big OpenGL expert : write a new GraphicDevice for OpenCASCADE.
