Ship models, Max number of verts/faces?

Hi All,

After only downloading Oolite a week ago, today, I've been looking into creating a new ship. I usually create models intended for 3D printing (via Shapeways). So far, I've managed to get the basic shape, with the UV map unaltered saved from Wings3D, given the ship some settings and created an OXP that works - WIP OXP downloadable here.

Now, with my 3D printing models, I'm used to creating as many faces as needed to get the detail from the printer, this usually means triangular faces have sides of 0.2mm or less and for a 1 x 2 x 3 cm model there may be as many as 750,000 faces with a filesize of 20-30 mB... obviously the same methods I use for 3D printing aren't going to work with Oolite, but I would like to be able to add a fair bit of modelled detail. My WIP example above, has 76 verts & 148 triangular faces. The question is;

How many verts & (triangular) faces is too many?

Cheers,
Paul

It depends on the machine that the game is running on - current versions of Oolite have no limit set (unlike earlier ones).

To give you an example though, Griff's classic scuffed Cobra 3 has 527 verts and 844 faces (on the main hull, not including sub-ents). So I think you have some scope yet to work in ;)

I have a ship with 7000 triangles, so don't worry about limits, there arn't any.

Thanks guys, I'll aim for 1k faces to start with and see how that pans out on my machine (spec'd a bit above minimum to run Fallout3).

There are still a few things modellers should be aware of -> https://bb.oolite.space/viewtopic.php?f=4&t=9491&start=7

Thanks for that Svengali. More food for thought.

"Vageta, what does the scouter say about his polygon count?"

Vageta: "IT'S OVER NINE-THOUSAND!"

Hehe, and it's only half done, it's already starting to cause problems for Wings3D, I think when I finally get it done it will be unusable for about 30 years until modern computers catch up :P

That level of complexity is no problem for contemporary systems. You just need to write an appropriate shader. ;-)
