Hi,
I want to do the following:
- render some object
- check if something is drawn
One soultion I could imagine, is to use a stencil buffer:
- clear/enable stencil buffer (ALWAYS)
- render some object
- iterate through stencil buffer and check if a write happened
this seems to be too expensive, because I just want to know IF something was drawn and not WHERE.
Is there some kind of flag with which I can do the following:
- set write flag to FALSE
- render some object
- check if write flag is set
greetings…
