Re: Problem reading in large textures in GeoTIFF format on Apple Mac Book Pro 17" and VTK OpenGL libraries

Hi,
         We tried this test on another Mac, with an ATI x1600 graphics card and it works fine. 

There is a problem with the NVIDIA GPU being able to render textures larger than 4K * 4K compared to the ATI one. The same application, with large textures does not work correctly with the NVIDIA GEFORCE 8600M GT

Is this a confirmed bug or issue?

Here is the configuration of the ATI card, but it was running on Mac OS X 10.4
