No, that is not true - the actual one was right.

This code makes no sence to me.
I am not sure but i think it's the same as
glRotatef(angle, 0.0, 1.0, 0.0) only.

Maybe You need something like this ...

Found something ...

// Redefine the viewport to the upper lefthand quadrant
glViewport(0,iHeight/2,iWidth/2,iHeight);

Should be ...

glViewport(0,iHeight/2,iWidth/2,iHeight/2);

// comment.

At NeHe page is working code for that.

Hi!

I am working on a project that uses a lot of static data.
As I use Texturing and LIGHTS - in my case VertexArrays are
out of the question. So I was forced to use Display lists.

And that...

Hi!

I don't belive that gluBuild2DMipmaps does't work!

Use (for testing) GL_LINEAR_MIPMAP_LINEAR for minification - so
You will see a smooth fade from one mipmap level to other. If there is a...

I have run several times trough my code, but wasn't able to fix it (instead earned 21 extra FPS http://www.opengl.org/discussion_boards/ubb/biggrin.gif) - so my problem is still actual.

Can You...

As Build2DMipmaps works and Yours not - your code must have some bugs. Can You show your code?

gluBuild2DMipmaps(GL_TEXTURE_2D

It works so ...
