Hi

I'm trying to implement wireframe drawing with hidden line removal. In the geometry shader I make lines from the input triangle. I plan to change the z-value in the geometry shader so that the lines are closer to the camera to avoid stippling (maybe this approach is wrong too). 

I want to do …
