That's easy - STEP has a simplistic RGB model while VRML has a much better material appearance model. The two models are worlds apart; STEP for example has no transparency, reflection, and ambient lighting but VRML does. This is why MCAD colors look so awful no matter what you do and every MCAD has a proprietary scheme for managing material appearance for the renderer. - Cirilo > -- > Cheers! > > Kevin. > > http://www.ve3syb.ca/ |"Nerds make the shiny things that distract > Owner of Elecraft K2 #2172 | the mouth-breathers, and that's why we're > | powerful!" > #include <disclaimer/favourite> | --Chris Hardwick > > > _______________________________________________ > Mailing list: https://launchpad.net/~kicad-developers > Post to : [email protected] > Unsubscribe : https://launchpad.net/~kicad-developers > More help : https://help.launchpad.net/ListHelp _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
