Re: [osg-users] How to create osg::Texture2D from osg::Vec3Array...?
Hi Kedar, On 28/06/12 19:10 , Kedar Kumbhar wrote: The normal method given in many examples to create a Texture2D, is using a Image file. Code: osg::ref_ptrosg::Texture2D texture = new osg::Texture2D; osg::ref_ptrosg::Image image = osgDB::readImageFile(Images/lz.rgb ); texture-setImage( image.get() ); Instead, I have a osg::Vect4Array in which I have color information (rgba). How can I use this Vec4Array to create Texture2D? Vec4Array is-a std::vector and contains a contiguous block of its base type, such as float. I haven't tested this, but you should be able to just call: osg::Image::setImage( width, height, 1, GL_RGBA8, GL_RGBA, GL_FLOAT, (unsigned char*) vec4Array[0], NO_DELETE); Hope this helps, Cheers, /ulrich ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Does OSG have INI config file reader?
Well, I don't want to use POCO just for reading INI. I wonder if OSG has one. If not, I'll have to write one myself, it's not that hard, but would be good if OSG has one already. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Does OSG have INI config file reader?
You could use Boost.PropertyTree http://www.boost.org/doc/libs/1_50_0/doc/html/boost_propertytree/parsers.html#boost_propertytree.parsers.ini_parser Then you can use ini files or chose a better format.

Re: [osg-users] Does OSG have INI config file reader?
Well, my intention is not bring any additional dependency apart from OSG alone. Speaking of better formats, does OSG has any config file reader? Or it's intentionally left for application to implement? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
