Quoting Cyrille Henry cyrille.henry@la-kitchen.fr:

...

1. Will this be integrated into the Gem CVS? Perhaps for v.89?

I'd like to. but it depend of what the other developper think of it.

It's fine by me. The code could use some changes like getting most of that case statement in the render function.

...

2. Will this be integrated into the stuff that Chris is doing with

vertex

...

arrays?

I'd like to. don't know much more now.

Unfortunately, the GL evaluators used in cube3d aren't compatible with the vertex arrays. Similar things can be accomplished with vertex/polygon approaches (see newwave as an example), but for defining simple bezier type curves, evaluators are probably simpler and faster. The next step would be NURBS, for which glu has a library of functions that I've never really looked at.

...

3. No makefile? How to build in linux/osx?

I don't know, I juste add it to gem project and compille everything.

Although I haven't built cube3d, it looks like it will work fine with the current CVS.

...

Oh my this is GREAT!!!!

thank's

cyrille

...

It better be part of gem-proper!!!!

Really good job Cyrille... and thanks for the windows compile of

Gem+CVS

...

too.

I hope you keep em coming.

Thanks for your efforts. Ben

...

hello,

I made a new primitive for gem : curve3D.... juste like curve, but in 3D!

you may find stuff here :

picts, source, exemple and gem.dll for windows user...

hope you'll like it...

Jamie & Chris,

On the note of vertext arrays is it possible to change the position of a number of underlying vertecies with relativly few control points? (like the spline control points in Cyrille's curve3d. or NURBS)

Please enclosed shapes! ;)

Ben

hey cyrille,

...great looking work: I'm going to try to play with it today...I'm not sure if it'll get in for the next release, but if it works on all platforms, I don't really see why not? The same functionality will be available with chris' vertex array stuff, but that is definitely for after this pending release...I saw that guenter and ben were talking about NURBS, and that just underlines the fact that we're just getting GEM to cover many of the modern opengl 1.2 features ;-)

keep it up! jamie
