model details -the head

films like buzz lightyear had really good fluid graphics and is a fair few year old now. When will we be seeing graphics like that and other movies. Hair/model details in them are always very good

According to Sony the PS2 could do that level of graphics on the fly... pfffffft :rolleyes:

For truley curved surfaces, you need to use NURBS instead of polygons.

Ah I think I was wrong about them not being supported by hardware. It says in there that they're included the OpenGL graphics library. So I'm guessing that means there is some hardware acceleration.

But I guess the problem is that polygons are much more efficient for certain details and it's probably difficult to mix the two .

"Today most professional computer graphics applications available for desktop use offer NURBS technology, which is most often realized by integrating a NURBS engine from a specialized company."

so hopefully we will see it used in games aswell soon?

The part in bold would lead me to believe no - as I'd imagine it would involve paying said company for a license. Added to the fact that most companies buy licenses for game engines as it is (and they're certainly not cheap), I can't see it happening.

Plus the fact it's described as an engine hints to me it's a bit power hungry.

I'd have thought it would depend how applicable it would be to integrate into a gaming system, as gaming is very different to professional graphical applications etc, as that article doesn't really go into what professional applications use this, I'd guess more CAD, and general 3D modelling systems use it.
 
i had times like that .... but its actually fun once get going... some days i am just missing that spark though and cant do anything right... those days i do somethin else :)

i plan on doing the entire battle of hoth at some point ... at my current rate that might be a few decades down the line though :p

as a budding 3d modeller i can tell u that nurbs are icky ;)

but then im not a fan of any curves right now... haven't quite gotten around to those tutorials yet

thought i would shamelessly add a link to my current piece of work into this thread... but as im nice i will only put a link instead of a picture :)

that looks nice and rounded. is a human head a lot harder to draw and make round? ive made rounder things in flash in seconds that the hitman head!
his nose and ears are round so why cant his head be, as it is one of the first things you notice

The way flash works I don't think there's a big performance hit for curved lines. But the whole basis of most game engines is on straight lines and triangles. So to make something appear rounder you just have to stick loads more triangles onto it, decreasing performance.

doesnt flash use vector graphics though to draw lines. arnt these just triangles? or am i completely wrong

No I think flash uses mathematical formulas to produce the shapes, hence it can make curved shapes that don't appear to straighten out when you zoom in closer. Notice how you can zoom in with flash and it doesn't become pixellated or appear to lose detail.

edit- Don't quote me on this as I don't know the details, it's more of an informed guess :o

That's what vectors are I believe in the terms of what flash uses, so geeza is right.

Oh yeah it is definately vector based, but it's not based only on straight lines.
