--- Quote from: Psawhn on September 30, 2007, 08:22:32 pm ---You're right, my estimates were, uh, overestimated.

In that picture you gave, I used the size of the golf ball (about 42.7mm) to estimate the size of the 20mm round (170mm long). My estimates based on my model's dimensions gave a length of 225mm. I also did most of my calculations for a single-ring barrel, and I just doubled that (including the margins I gave for the center and outside, doh) for the dual-ring barrel. (I also overestimated the margin I need between rings, and for the outside.)

Revised estmates give about 800-900 cm diameter for a double-barrel, and half that for a single-barrel. That's definitely better than 1.4m.

My width isn't off by quite as large an error - the 20mm round looks like about 28.8 (let's call it 30) mm, and my estimates gave 35mm. Using those figures, and increasing the length of the barrel to an even 2.0m, one can fit about 6500 (6533 precisely). We can probably bump it up to 6540 to account for extra bullets in the conveyor belt, and make it a nice even number.

Of course, the weight of that many bullets isn't insignificant, but we can probably say that the late 21st century engines and materials are strong enough to account for that. :)

Edit: More work on the drum, this time with some rails to lead the ammo into/out of the drum.

Nice one. I'd much rather use a big drum like that (with a single round standing in front for reference) as the SHIVA ammo model rather than just showing a single round.

Psawhn:
Here's the model for the ammo drum, and two textures:

I had to take out the rails and the belt, but the polycount is still high: 2106 triangles. That's using only 1 layer of minimum-resolution bullets, too.

Individual bullets out in front look a bit small and out of place, so I took 'em out. Maybe you guys could find a use for the above stills in the game? :)

Edit: It helps if I post a picture, haha.

sitters:
Cant you render the hi poly front of the drum and take an snapshot, then replace the bullets by an texture ?

Then the high poly count is gone. ;)

Psawhn:
That's exactly what I did for the wall behind the bullet, actually. :) I figured that way I can have the 3D of a layer of bullets, with the effect that there's a lot more underneath. If I simply draw a cylinder with everything baked onto it, then it looks like a cylinder with a painting of bullets on the front. :D

Mattn:
the question is: how big will we display the model in the pedia? i suppose the displayed model is that small, that you don't even see any single bullet, but only a yellow/blue ring of bullets.
