[osg-users] 3D osg::Image allocation size problem

Hi, I am developing a scientific visualization application using Qt and Openscenegraph. I am trying to create a 3D osg::Image to add to an osgVolume. I am having problems allocating the image data when I call the allocateImage member function (see the code snippet below). The allocation work

Hi Josiah, Without a stack trace it's very hard to know exactly what is amiss. My best guess is memory allocation error that isn't being handling elegantly. Have a look into the Image::allocateImage() implementation to see what is happening during the allocation. As check on paper how much memor

Hi SMesserschmidt I think you are right about the size issue. With sizes less than 640, the getTotalImageSizeIncludingMipmap() function returns the correct size that is 640 x 640 x 640 x 4 x 4. With sizes between 640 and 1024 it returns the wrong size that is even less than the maximum size of
