Kliment & Vesa, All of this is true - for autorouters. This whole thread started with Altium's videos about the improvements to their interactive (semi-manual) router. P&S actually use very few strictly topological concepts (in the case of Kicad P&S, mainly in the optimizer part of the code)... BTW, I'm surprised by the smoothness of the animation in A***m's promotional videos. Did they use some editing/postprocessing to make them look this way? :D Tom > > Hope this is helpful. > > On 02.12.19 17:59, Tomasz Wlostowski wrote: >> On 02/12/2019 17:40, Vesa Solonen wrote: >>> topological routing will >> >> Could you please explain what 'topological routing' does mean (other >> than being marketing buzzword used by some companies) and what exactly >> it has to do with topology [1]? >> >> Tom >> >> [1] https://en.wikipedia.org/wiki/Topology >> >> >> >> _______________________________________________ >> Mailing list: https://launchpad.net/~kicad-developers >> Post to : kicad-developers@lists.launchpad.net >> Unsubscribe : https://launchpad.net/~kicad-developers >> More help : https://help.launchpad.net/ListHelp >> > > > _______________________________________________ > Mailing list: https://launchpad.net/~kicad-developers > Post to : kicad-developers@lists.launchpad.net > Unsubscribe : https://launchpad.net/~kicad-developers > More help : https://help.launchpad.net/ListHelp > _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
