Yes, I load a certain number of images (a lot of images, for example 20.000 at 1400x1050 resolution-jpg or tga) with readImageFile at the initialization of the application and I load them in memory (inside std::vector<osg::Image*>) at startup. To visualize all the images in a smoothing way (like a movie) with play, forward, rewind, skipToNextFrame, skipToPreviousFrame command I iterate the array elements. My problem is that I can load inside the vector a little number of images (about one hundred). Then I have not enough memory error. I suppose that this error is normal because I load all the uncompressed images in memory (also with .jpg) and I'm looking for a method to solve this problem. I have already tried to destroy old images but in that case there is the following problem: the process of loading images from my hard disk to ram require about two times the time required for visualization at 30 fps so it arrives a moment where the buffer is full. As regards ramdisk probably it could be a solution (implementing parallel threads) but on Windows it has portability problems due to the installation of a driver that probably I cannot install on target PC of my application. Thanks all for the useful answers (you are giving me new roads to follow) Francesco Argese ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=7514#7514 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
