Render callbacks

Geoffm · 18th November 2015, 08:41 AM

I have created a render callback for each object in my scene (using plugin in C/C++). The callback is called 8 times for each AC3D object (if 4 views are displayed) or twice per object if 1 view is on display. The callback argument 'is_primary_render' eliminates half of these callbacks.

I only want to get the callback once per redraw, so I would like either:
to identify the window which is causing the callback OR
have a type of callback which occurs before all views are updated.

I think there would be many uses for the first option - perhaps 'is_primary_render' could be an integer to identify the ACView being redrawn (or 0 for updates that are not window related).
