I am very new to computer graphics and OSG/OpenGL. I need to figure out how to write a simple textured rectangle to a .tif file. I've found many examples of this but some are so complicated I can't understand them.
What do you mean by 'write a texture rectangle'? Do you want to save the rendered frame to a file? If so then please take a look at the osgscreencapture example - in brief you need to add a capture callback to read the rendered frame and save it to a file.
Here is the code I have so far, when I run it I can see a single rectangle with the road texture on it. I have some code that does create a result .tif file, but I can't view it. I'm sure I'm missing some things. I'd appreciate any help, I know this is probably a simple question...
'Can't view it' as in it's empty? Or not a tif file? Please give us a bit more detail to work with.
//write image code I've been playing with osg::Image* resultImage = new osg::Image; resultImage->allocateImage(3000, 3000, 0, GL_RGB, GL_UNSIGNED_BYTE); osgDB::writeImageFile(*resultImage, "D:\\C++_Projects\\result.tif");
This will write an empty image (probably black). Cheers, /ulrich _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
