re: D3DXCreateTeapot and reverse engineering?

IMHO, our criterion is "we only need to implement what apps really need",
and for the moment, that app probably could live with a stub for
D3DXCreateTeapot.   When we run into a complaint about
our lousy teapot, we can create a better one.  So relax,
just do a stub, and move on to more important things.

Also, as Roderick says, sucking tables out of Windows is
not ok, for copyright reasons.

That teapot looks a lot like a ball/sphere :)!

Very well. I will only devote a very limited amount of time to looking
at the teapot.

I am currently looking at the GLUT code. They seem to have simplified
this quite a bit compared to Windows data - at which I will not look per
all your comments.

I do not really know much (anything) about OpenGL but have pulled this
code as a combination from:
http://mindfuck.de-brauwer.be/articles/glut/
http://www.it.freebsd.org/pub/Unix/NetBSD/NetBSD-current/xsrc/external/mit/M...

Any ideas how one could quickly look at the raw vertex buffer data using
OpenGL?

Thank you

How raw do you want to have it:
http://cgit.freedesktop.org/mesa/mesa/tree/src/glut/glx/glut_teapot.c
? ;)

I believe the GLMap2f functions are actually creating further vertex data...
I could be wrong though. Thx

I don't know if this is entirely necessary for your purpose, but
OpenGL has a feedback buffer which can be used to capture vertex data.
 There's an example here

Thank you. I will take a look at this tomorrow morning.
