 | | Seemingly insane poly counts in official games - how?
|
|
Hi y'all, I'm just curious if anyone knows how Lego gets away with their models having studs and tubes and everything in their games? It seems like the poly count would be unplayably ridiculous. -Stefan- (19 years ago, 22-Jun-05, to lugnet.cad, lugnet.games)

(...) To which game are you referring? All the ones I've seen use surface textures, not actual polygons to simulate studs. Allister (19 years ago, 22-Jun-05, to lugnet.cad)

For the most part you're right, and that's something I had not realized. However, there are a few instances that I've seen in Lego Island, Island 2, where an ingame model actually has studs. Lately of course, there is the new SW game: (URL) So I (...) (19 years ago, 22-Jun-05, to lugnet.cad, FTX)

(...) I'm guessing it is because each in game object is a single instanced mesh that has been severely optimised rather than a collection of individual part and subpart meshes that are all being drawn regardless of whether they are visible or not (...) (19 years ago, 22-Jun-05, to lugnet.cad, FTX)

(...) Hi Stefan, My guess is that the studs are a special primitive which is just attached as a bitmap. A cylinder is very quick to render and so a simple routine to map an angle to a cone bitmap which is then added in the right place wouldn't be (...) (19 years ago, 22-Jun-05, to lugnet.cad)

(...) Well, you're partially right, but the amount of polys per model would still be ridicilous (sp?) due to the tubes and studs still existent on the top and bottom. (URL) (...)

(...) I hadn't thought of that. So the studs don't quite exist, the game engine just knows where to draw them, right? Indeed, the studs don't seem to cast shadows, though they are shaded. -Stefan- (19 years ago, 22-Jun-05, to lugnet.cad)

(...) One way to do this would be project rays through a model, selecting rays with random angles. Keep track of which polygons in the model initially (and finally) intersect the ray -- these polygons are visible. Repeat this process for enough (...) (19 years ago, 22-Jun-05, to lugnet.cad, FTX)

(...) Hmm, How many poly's in that model? and what game is it a mod for? Balancing poly budgets in games is a non-trivial problem, how you do it is very dependant on the game, how many instances of a model is the game expected to render at once? how (...)

That woulda been cool to see. Unfortunately, the models in simcity are actually just image files, iirc. Thus there are no polys. -Stefan- (19 years ago, 22-Jun-05, to lugnet.cad, FTX)

I am wondering whether you could do this: Pass a plane through a model along the X axis. Keep track of which polys intersect the plane. If these intersections then intersect with each other, they will form 2D shapes on the plane. If any of these (...) (19 years ago, 7-Jul-05, to lugnet.cad)
