[osg-users] Different implementation of QT multitouch

2014-12-09 Thread Jason Beverage
Hi all, I'm sending this in to start a discussion on the way that multitouch support is implemented in the GraphicsWindowQT class. Around the time that the new gesture code path was added I had put together a different approach for a customer against an old version of OSG but never got around to

Hi Umesh, You seems to be trying to overcomplicate things. The OSG supports a full range of pixel formats and data types. You don't need to lift a finger, just assign the Image you load and assign it to the texture and it'll do the right thing by you. If you need to used different formats the

Hi Robert, Thanks for the prompt response. I am not talking about compressed textures. By RGBA8 i mean typically R8G8B8A8. I believe that OpenGL also interprets in this way. Typically if we use an OpenGL App in which we have to read a PNG image that is in RGB8 format, we may use LibPNG library t

Thanks for weighing in, I guess I will have to try various combinations of operating system and FFMPEG releases to get to the bottom of this. As a last resort I could imagine myself editing the ffmpeg plug-in source code. I would also try to add variable speed playback (without audio, as this wou

Hi Christian, I have just tried your video with osgmultiplemovies with svn/trunk but it comes out black. I run the same movie in osgmovie it comes out fine though. No stats though so doesn't reveal any particular problem. I'm not the author of the ffmpeg plugin so I can't provide any particular

Hi, the OSG 3.2 seems to have a problem with reported timestamps while replaying movies. I haven't tested never OSG development versions yet. The issue occurs close to the end of an MP4 file. The timestamp wraps around back to 0 before the end of the file is played out. There are also side effect

Hi, I am a 3d generalist, working for a lab where we make simulators. People in this lab have been working with 3ds Max, OSG and osgmaxexp for exporting. We have been creating basic 3d graphics for their simulators, but I would like to cheer them up with some features like bump mapping and spe

Hi Umesh, The OSG just passes data to OpenGL Textures via the combination of osg::Texture* and osg::Image. The plugins load the osg::Image that get assigned to the osg::Texture. The osg::Image and osg::Texture classes both have the settings for the data type and pixel format of the data. If Open
