Hey All

I just came across Delgine a few days ago, and until now it fits all my need for a spare time project!

But, I have a question about the polygon data in the *.dmf export.
If the number of vertices (for one object) is 4, does it mean that the polygon is a quad ?

In can easily thing of a polygon with 4 vertices not being a plane quad, and hence its not possible do calculate one (and only one) normal for that polygon. Of cause if the number of vertices for one object is 3, it’s a triangle and we have one normal for this prime.

Thanks ..

Hi there Mille and welcome to these forums!

To answer your question: a polygon that has 4 vertices does _not_ have to be a quad. It is perfectly possible to deform a polygon so that it is not a plane polygon anymore. I would suggest triangulating your scene before performing your own calculations on it. DeleD does not triangulate by default to ease modelling operations by the user. DeleD does provide triangulation routines for convex polygons though, as I'm sure you've already discovered.

OK, thanks for the quick reply!

Sorry for submitting foolish questions, but how do I triangulated a scene ?
I suppose it can be done within the Delgine Tool before doing export to *.dmf ?
(just can’t find where)

Thanks ..

Stupid questions don't exist.

You can triangulate a scene by selecting your entire scene (ctrl-A) in Object Mode and then using the Triangulate function. Also, Fan triangulation is probably best in your case.

Ohh yes baby, I'm back on track, THANKS.

I've been working with Quake maps and 3ds of cause, but DeleD is defiantly
more easy to grasp! Just want I need for my spare time first person game.

I got a link from the gamedev forums, DirectX forum.
I really like Delgine, its easy to learn, and the *.dmf is clean and simple!
