i’m new with openGL and i’ve been trying to do volume tiling and i’ve got a problem.
i’m using texture objects. so, for all the tiles in the volume i call glTexImage3D. i noticed that openGL makes its own copy of the texels so i end up with 2 versions of the volume on maintained by openGL and one is mine and i use it for other stuff.
is there any way to make the openGL just read the data whenever needed and not copy it? any thoughts are welcome :D…
thanks in advance.
