how to use GL_ARB texture_non_power_of_two

hwo to use GL_ARB_texture_non_power_of_two any examples? and does OpenGL 1.5 support it?
Thanks

and does FX 5900 support this extension?

You shouldn’t have to do anything special to use this extension. Simply check if it’s supported, and if it is you can use non-POT textures using regular glTexImage2D() calls. I don’t think it’s supported on the FX 5900 though.

No, ARB_texture_npo2 is currently only supported by GeForce 6 series, FX-series does not support this extension.
And yes, ARB_texture_npo2 is included in OpenGL 1.5 core. So exactly GeForce FX series and Radeon 9x00 series do NOT support OpenGL 1.5.

It’s only supported on the geForce6 series at the moment.

is there any chance to have a support for nv30+ (even software emulation) any time soon or is this an nv40+ only feature?

No, this extensions is not core according to glspec15.pdf
It is a new extension and most hardware don’t support it, therefore it is not CORE.

All FX a and 9x00 drivers support GL 1.5

It was on the table for inclusion in GL2.0 though, but I don’t know if it’s going to make it.
