Sorry,I am a programmer who is a Chinese. I cannot speak English very well.I hope you can understand me.
I use the function gluBuild2DMipmaps to load the texture that not power by 2. But it was scale the picture. The picture weight is 300. I use gluBuild2DMipmaps load it .Then I use glGetTexLevelParameter to get it’s weight is 256.It said gluBuild2DMipmaps is scale the picture from weight 300 to weight 256.That is so bad. Because the picture is seems so ugly.So I want a function to instead of the gluBuild2DMipmaps to load the texture that not power by 2.
