I want to apply an RGB texture (size 1024x32) on a very big face with
the same ratio (width x height).

With no texturation parameters, rendering is horrible (bad color pixels
appear between texels). When i change texturation parameters
(MAG_FILTER), the result is the same.

I try the sample program 'mipmap' compiled for Open GL and, the result
is the same. If i resize my texture to set it like square, rusult is the
same...

I try to use Open Inventor and if i set SoComplexity node to hight
quality texture, result is perfect !!!! Smooting is good beteween
texels.

So, what is good parameters on Performer to have a good rendering ??

Thank you very much for your help.

Gilles.
