[PROPOSAL]: Cleaner edges also for non-logarithmic depth buffer
I did some tests and I think that after merging #1788 now edges are rendered in a much nicer way when log. depth buffer is enabled than when it is not!
@xeolabs, Would you be interested in introducing the gradient technique also when log. depth buffer is not enabled?
The main changes I see that would be needed and could impact performance is to propagate the Z value from the vertex shader into the fragment shader, and the calculation of dxf and dxdy from the fragment shader.
Other than this the change is conceptually very easy 🙂
Hi Toni! Yes I think it would be good to use the gradient technique in non-log depth mode. The performance hit is OK, because users often use FastNavPlugin to hide edges while moving the viewpoint.
@tmarti This would be a very nice improvment too and could be interesting regarding performance compared to the log. depth buffer. Do you already have a draft implementation of this which you can share?
