20150119 08:08:29 <monsieur_max> hi there
20150119 08:26:12 * eclesia (~husky@anon) has joined #jogamp
20150119 08:26:20 <eclesia> good morning
20150119 10:03:55 * doev (~doev@anon) Quit (Quit: Verlassend)

20150119 12:49:31 <eclesia> question : is there a way to define an additional alpha value for blending in opengl ?
20150119 12:50:54 <bruce-> in what context?
20150119 12:53:54 <eclesia> context ?
20150119 12:54:08 <bruce-> what are you going to do with that additional alpha value
20150119 12:54:43 <eclesia> to reproduce the usual porter duff rules
20150119 12:55:27 <eclesia> or like in java2d
20150119 12:55:33 <eclesia> alphacomposite
20150119 12:57:18 <bruce-> but then the alpha values that come from destination buffer and the source fragment are enough
20150119 12:59:18 <eclesia> that would require and extra step/texture then if the alpha is not 1
20150119 12:59:42 <bruce-> you can also set an alpha constant
20150119 13:00:08 <eclesia> that's what I was asking ^^
20150119 13:01:27 <eclesia> nevermind, back to work.
20150119 13:01:36 * eclesia parsing xml ...
20150119 13:03:09 <monsieur_max> yay ! xml !
20150119 13:04:54 <bruce-> eclesia: I think it is set through glBlendColor but I never had a need for it
20150119 13:04:56 <xranby> eclesia: do you plan to support badly formatted xml as well? "tagsoup"
20150119 13:05:38 <eclesia> xranby: using jaxb :x
20150119 13:08:27 <xranby> http://xml.coverpages.org/Cowan-Tagsoup.pdf <- tagsoup parser main feature is -> "Just Keep On Truckin'"• Never throws any syntax errors of any kind
20150119 13:08:49 <bruce-> :)
20150119 13:10:36 <bruce-> I like how nekohtml now and then prints complaints on stderr regarding nested <a> tags
20150119 13:11:18 <bruce-> dealing with scrapers on public sources makes me very sad
20150119 13:11:35 <xranby> i feel tempted to replace xml4j with tagsoup would same me the stress of fatal errors in production when some xml fails to parse and the user wants to see some of the data within
20150119 13:13:37 <xranby> i generally like the data creator to be as strict as possible while a data parser to be as relaxed as possible
20150119 13:14:00 <bruce-> sadly the data creator is sometimes a fool
20150119 13:15:14 <xranby> sure, in my work of field the data creator == instrument manufacturers has to improvise because there is no specification that you can follow strictly
20150119 13:15:36 <xranby> thus no customer has enforced any standard
20150119 13:16:09 <xranby> the result is a mess with all manufacturers formating data in its unique way
20150119 13:17:34 <xranby> the parse creator has made this situation a busniess model, because nothing can simply "plug-and-play" with laboratory instrumentation in hospital settings
20150119 13:17:48 <xranby> they actually expect things not to work and charge a lot to write the parsers
20150119 13:19:24 <xranby> the situation has become -> data creators == sloppy and data parsers == strict -> nothing work -> healthcare funds wasted
