I am trying to use rectangular textures with sizes on the
ordre of 2048x256, or 4096x512.
On my O2, both Performer and OpenGL stop displaying the texture
on the objects when the size becomes larger than 1024 on the side:
But there is no complaint by either library, which makes it difficult
for me to understand what's going on.
a 1024^2 imag works fine, on the other hand a 256x2048 imag does
not appear...
--> is there any way to find out at run-time whether a given size
will work? what exactly is happening, and who is responsible
for the limitation? it seems that on an iR board the larger
textures work OK, but I thought on the O2 there was no limit on
texture memory, besides a 2048x256 texture is smaller than an 1024^2
texture...
Thanks in advance for any help!
