Considering my question in Game Developement:
it seems that, there's no way to show an image bigger than the MAX_TEXTURE_SIZE in OpenGL (I'm not sure yet, looking forward to more answers in Game Developement)
In my case MAX_TEXTURE_SIZE = 8192 but my image is a 16997x15931 which can be shown in openGL based on my current knowledge about this API.
Just tobe curious, and maybe they're using a toolkit or API which is not free
What way programs like Global Mapper, ArcMap and ArcScene manage to show high resolution geotiff images for example bigger than 15000x15000 with high performance?
What toolkit, API, 3rd party library do they use for
display tasks and
2D or 3D rendering in their programs?
I highly doubt that image-pyramids is the concept related to my question?
if it's true beyond answering my question about APIs please introduce me a link in GDAL documentation that has an excellent tutorial about pyramids?
