Change to OpenGL rendering of HSI cubes #618

Open robmcmullen opened 12 years ago

robmcmullen commented 12 years ago

[Trac time 20090424 231126Z] When opening very large images in the hyperspectral image view mode, the program can run out of memory because it tries to allocate one large bitmap for the whole image.

Switching to OpenGL will allow the image to be split up into smaller textures, and we will get a lot of other things for free like zooming, panning, rotation, etc.
