Hi Lorenzo, I was aware of that change / improvement, but for some reason (maybe because I changed for another laptop/screen) it was more noticeable for me theses days.
Sorry for the noise ;) Mario ________________________________________ From: Kicad-developers [[email protected]] on behalf of Lorenzo Marcantonio [[email protected]] Sent: 30 August 2016 19:13 To: Kicad Developers Subject: Re: [Kicad-developers] Blured text on OpenGL On Tue, Aug 30, 2016 at 04:11:57PM +0000, Mário Luzeiro wrote: > Hi all, > > I had a feeling yesterday, on the openGL mode that looks different: low-res > blurred interpolated font. > I may was a bit blurred myself, but I found other users complaining about the > same: > > https://forum.kicad.info/t/switch-of-blurring-of-pad-text-in-new-opengl-engine/3837 > > Any one noticed? Any changes that can causing this? Probably it's the new bitmapped font... consumer GPUs are optimized for munching textures, not vectors, so on very busy board the vectorial font was too slow to handle. Now is done with quads (4 vertices) AFAIK, one for each character. In comparison the vector text need to send to the GPU something like 6 vertices for each line segment in the font, more or less an order of magnitude of difference! The cons is that now since the font is bitmapped the resolution is finite and what you call blur is the bilinear filtering of the character images... This should explain the reason, for the details maybe the developers that did it have more informations. -- Lorenzo Marcantonio _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
