Ofcourse you should ask him some basic stuff like :
What's the difference between a vertex and a vector.
or : How do you normalize a vector.

If he/she doesn't now those basics you shoudn't even...

Ofcourse it would be cool http://www.opengl.org/discussion_boards/ubb/cool.gif to have a 64bit Z buffer !

I just wanted to emphasise this problem.
This mistake is made in several examples I found on the web.

This could save some people a lot of debugging / posting time. ...

Nice site, renders fine in Opera7, IE and Mozilla.

Something I just noticed :

// Gives INCORRECT Z value
GLdouble l_dZ;
glReadPixels(a_iX, l_iY, 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &l_dZ);

// Gives CORRECT Z value
GLfloat l_fZ;...

Hi,

I 'm drawing an object that can have separate textures applied to each polygon

But for some reason my viewers slows down after the first display list compile.

1st compile, # textures...

Btw... I just registered. ;-)

The problem is not the texture switching.
All poly's are sorted by texture.

So the problem still remains.

1st compile, # textures applied to faces.
--> glCallList slow response

2nd...

Indeed, that would be ideal.
But what I want is to be able to assign (bind) a texture to each polygon separately if needed.

Fe. I have separate textures for arms, legs, face, etc for my...

In the meantime I also tried to generate the texture objects ouside the display list and use (bind) them inside the display list.

Even that results in a slowdown.

Any ideas ? Somebody ? :-/

hi guyz,

I have a display list containing a bunch of polygons with a texture object assigned to it. (bindTexture is called inside display list generation)

Now, when I generate the texture...
