Jason Posted September 13, 2003 Share Posted September 13, 2003 Hi there, Is anyone interested in collaborating in making an EXR file reader/writer for Houdini and sticking it on the open dowload forum at Savannah Non-GNU downloads here as I see has happened with the Renderman and Photoshop EXR display drivers? Thanks! Jason PS. Anyone know whether HDK users are allowed to opensource their plugins? Quote Link to comment Share on other sites More sharing options...
eloop Posted October 16, 2003 Share Posted October 16, 2003 Hi Jason, I'd be interested in using it And if I wasn't so snowed under I would like to help out ... I spoke to one of the sidefx guys about the possibility of this at the siggraph meeting this year and they were concerned how the openexr code would sit in the HDK universe since the openexr lib requires C++ exceptions enabled (and handled) whereas HDK doesn't, possibly a platform dependant problem that would need to be resolved. -Drew Quote Link to comment Share on other sites More sharing options...
Jason Posted October 17, 2003 Author Share Posted October 17, 2003 Oh, I didn't know that. Also I've heard that the .pic format uses different image classes than the HDK ones because of the Deep Raster capabilities. I wonder if this is true? The major benefit would be to store those multiple channels inside the EXR format, but if the HDK i/o classes doesn't support them, then half the yumminess of the format is lost. Perhaps we can get a SESI person to confirm or deny this? Or maybe SESI will implement it for us;-) Quote Link to comment Share on other sites More sharing options...
Wolfwood Posted May 6, 2004 Share Posted May 6, 2004 Maybe SESI will support OpenEXR if we ask nicely. Quote Link to comment Share on other sites More sharing options...

JColdrick Posted June 11, 2004 Share Posted June 11, 2004 Actually, there was some weird intensity scaling problem in there which seems to be fixed now - woohoo! Here comes some small, fast, hot, mblurred reflection hits! (It's sad, really, the things that turn us on...) Cheers, J.C. Quote Link to comment Share on other sites More sharing options...
ivan Posted June 18, 2004 Share Posted June 18, 2004 uh, open exr? sure, it'd probably be pretty damn easy, just an exercise in getting the openexr code to compile... in my copious free time... Quote Link to comment Share on other sites More sharing options...
Jason Posted June 18, 2004 Author Share Posted June 18, 2004 Houdini 6.5 has support for EXR already now:) So we can stand down... Its only RGBA support right now, but I believe that they are going to give deep raster support to it a bit later. Quote Link to comment Share on other sites More sharing options...
edward Posted June 20, 2004 Share Posted June 20, 2004 Look what you started, Jim! Quote Link to comment Share on other sites More sharing options...
Jason Posted September 8, 2004 Author Share Posted September 8, 2004 Look what you started, Jim! 12095[/snapback] Is the EXR support still only RGBA? Saving deep rasters from MPlay in 7.0.161 still only saves the RGBA. Quote Link to comment Share on other sites More sharing options...
Guest xionmark Posted September 8, 2004 Share Posted September 8, 2004 PS. Anyone know whether HDK users are allowed to opensource their plugins? I think it's OK ... I've had 2 super simple plugins on the web for a while and never heard anything from SESI ... of course I'm working with academic licenses and can't charge for the work, maybe that's the diff ... not sure. Oh, do you mean to post on something like Source Forge ??? --Mark Quote Link to comment Share on other sites More sharing options...

Jason Posted September 9, 2004 Author Share Posted September 9, 2004 Actually, what is the license agreement and such with SourceForge? Would it be possible, or even a good idea to have a HoudiniHDK project and allow people to up/download source from there? Can a plugin to commercial software be considered Open Source? If so, which license? GPL? MPL? Public Domain? I know nothing of this type of thing. I tried to look at the publically available OpenEXR plugins to Photoshop and PrMan and saw nothing of any license agreement, Quote Link to comment Share on other sites More sharing options...
eloop Posted September 9, 2004 Share Posted September 9, 2004 Things like Liquid and mrLiquid would fall into that category so it seems possible. http://www.colindoncaster.com/tools/liquid.html http://sourceforge.net/projects/mrliquid/ -Drew Quote Link to comment Share on other sites More sharing options...
