With the contempo fizz of the ISSCC appointment a few canicule ago (click actuality to see the aboriginal report), there has been a lot of belief and skepticism apropos the arise chipsets from Sony Computer Ball and Toshiba. With the ability the chipset is reportedly able of (55 actor polys per second, Bezier surfacing), is this absolutely the accuracy of Sony’s abutting PlayStation, and if so, is it absolutely accessible to get CG affection adumbration out of a videogame system?

After coursing through all the capacity of the announcement, we got in blow with L. Anthony Gaud, Art Director at Mainframe Entertainment. He’s formed on the company’s three key CG television programs, ReBoot,Transformers: Beast Wars, and War Planets. We best his academician to get a acceptable abstraction of how the specs of the arise capabilities of the accessible PlayStation 2 arrangement analyze to the high-end workstations in use today at CG companies such as Mainframe.

IGNPSX: So you saw the achievement numbers of what ability possibly be the Playstation 2’s clear capabilities. What do you anticipate of them?

L. Anthony Gaud: I anticipate that bodies conceivably are overestimating the ability of this new chipset, at atomic in account to its absolute apple polygon-pushing prowess. While the PlayStation 2 could apparently advance about 55 actor polygons, the absolute apple use will be apparently be afterpiece to about 6 or 8 actor already things like Bezier ambit geometry, arrangement maps, bold physics, AI, and added bold advice is addressed. The important catechism is how abounding polygons can the PlayStation 2 cede to the screen. There is a audible achievability that processing bottlenecks ability absolute the polygon apprehension cardinal to a added ‘down to earth’ akin than the 13 to 30 million. We’ll accept to delay until Sony reveals the complete specs of the accomplished system, but I apprehend about Voodoo 3 performance. It is acutely no slouch however, and it comes abutting to the abstract absolute of affectation capabilities for best monitors.

IGNPSX: How do these abstracts analyze to the systems you guys use over at Mainframe?

Anthony: It’s absolutely apples to oranges. For the best part, we use Silicon Cartoon machines that weren’t congenital on a polygon per additional criteria. The SGI Octane for instance alone pushes about 450,000 polys per second. They are aimed at the aesthetic aspect of computer graphics, instead of actuality a gaming environment. It would be nice however, to absorb a real-time examination of currently advancing productions application the affectionate of ability the PlayStation 2 or alike the Dreamcast can put out. That would accredit animators and admiral to accomplish changes quicker and added interactively than they can now.

If ¿ and that is a big if ¿ the specs mentioned at the IEEE appointment are true, you could apparently cede a real-time adaptation of Mainframe’s flagship alternation ReBoot. Some of Mainframe’s best tech bodies did the basic algebraic and it COULD be done, admitting with a accident of arrangement detail, apprehension quality, and conceivably facial animation. There’s a big ball idea: TV shows with endings that gamers can interactively decide. I’d never leave my couch!

IGNPSX: One of the chipset’s arise capabilities is article alleged Bezier surfacing. What, in a nutshell, is Bezier surfacing? How do you use it in Mainframe productions?

Anthony: Bezier curves are curves accept 4 ascendancy points, 2 of them ascertain the endpoints of the curves and the added two ascertain the ambit itself. Generally they are added automatic to use than nurbs, which accept ascendancy credibility that lie alfresco of the ambit itself and can be adamantine to acclimatize by artists types (myself included). Bezier ambit functions accept been about for years in aesthetic applications like Adobe Illustrator and Photoshop, as able-bodied as best of the above 3D clay programs. Nurbs can actualize smoother curves than Beziers, but Beziers can aftermath added bizarre and acutely angled curves. At Mainframe, like best assembly houses that advance computer graphics, computer models are congenital application combinations of Beziers, nurbs, and polygons, depending on the clay aftereffect required.

IGNPSX: It seems this is absolutely new to bold developers, do you anticipate they will accept bezier surfacing quickly?

Anthony: Definitely, back best bold models are already complete application Beziers (and nurbs) that are again burst bottomward into polygons for display. Developers will readily acclimate to the use of Beziers, and in fact, it may alike accomplish their lives easier.

IGNPSX: If Bezier surfacing is mainly acclimated for rendering, in what way could developers use Bezier surfacing in real-time gaming?

Anthony: For starters, it makes for a admirable polygon administration utility. Distant altar whose shapes are authentic by Bezier geometry can be displayed with beneath polygons, absolution the processor from accepting to cede abundant polygonal accomplishments models. This can be acclimated to finer annihilate article ‘pop-up’ and additionally acquiesce amateur to become livelier than absolutely polygonal bold worlds. Typically “mundane” altar like the bushes in Zelda for instance, can become animate by angle and acceptable in the breeze. If you accept anytime apparent “A Bug’s Life” you apperceive the aftereffect that capacity like that can accompany to an environment.

And while Bezier surfacing allows for abounding enhancements in the cartoon category, (smother curves and added circuitous models), what I’m REALLY absorbed in are the concrete developments that can be activated to Beziers surfaces. Because Beziers are algebraic formulas, they can be adapted on the fly (unlike polygonal geometry, which is for the best allotment durably pre-defined). A polygonal anachronistic wouldn’t be able to accept bouncing bark and coil anatomy like a bezier anachronistic could because Beziers acquiesce for absolute time anamorphosis of models. This can be acclimated to actualize added astute baptize and access furnishings as able-bodied as the all-important seamless bold character. These characters would accept abundant added detail than polygonal characters could, that would be arise the afterpiece they arise appear the camera. To use a bolt phrase, Bezier geometry allows for a archetype about-face in gaming, area the focus can be taken off of cartoon and placed into creating a added alternate gaming world.

War Planets’ Graveheart demonstrates the ability of Bezier curves. Look at the arm of anniversary of the models and you’ll see how enabling Bezier can advice accomplish the aforementioned 3D archetypal arise added detailed.
