Hi, I'm trying to send float data beyond the range of [0, 1] to a texture. I set the texture and the image format to float. If the image size is power of two, things seems to be ok, but if the sizes are different it seems the the gluScaleImage command truncate the values in some manner (it's even not clamping everything above 1.0 to 1.0 and everything below 0 to 0, but some truncation that leaes only the fraction of the value). Any ideas how to prevent it from happenning?
thanks, Guy
