I would like to use another form of hilighting my selected objects. Since my Objects have quite a lot of edges, i would like to stop drawing contour lines of all edges.
The reason for this is the way my objects are displayerd when zoomed away: the Objects base colors are almost invisible since the selection lines are all rendered, no matter on what zoom level.
Can this behaviour be changed?
Could i just modify the base color of the selection instead?
Would the latter be possible without modification of OCCT's sources?
My only other idea of a workaround is to disable Selection altogether, do my own picking and manging selection states of my objects with application code. This will be cumbersome.

I solved this one (kinda):
with a valid Handle(Ais_Shape):
myAis_Shape->SetHilightMode(3);
Leads to Highlighting (and selection marking) of the entire Shape with a single color.
While this looks not to well for transparent areas, it at least reduces the lag when a lot of objects are highligthed.
As it is not directly mentioned in the Documentation, i post a list of hilighting modes available:
Mode 0: Standard behavioue (wireframe)
Mode 1: solid color marking
Mode 2: bounding-box marking (with a dashed line)
Mode 3: No marking at all ( might be possible to texture map here, but i dont know)

Hi, Author:
Very helpful, but how to change the highlight color?
By the way, as the documentation you mentioned, is it "Reference Documentation" you got after installation of OCC? I had hard time to browse/search through it.
Thanks,

Hi James,
On changing the hilight color:
you can use AIS_InteractiveContext::SetHilightColor(Quantity_NOC_YELLOW)
