che computer usavano i primi film in cgi?

[lele980]

stasera mi sono rivisto per l ennesima volta un film della mia infanzia GIOCHI STELLARI (alias l'ultimo starfighter) a distanza di 26 anni trovo ancora gradevole e ben sviluppata la cgi delle varie scene

ma all'epoca che computer usavano e quanto tempo ci voleva per sviluppare scene di questo genere?

[CYRANO]

Usavano i Cray penso...

bel film , uno dei miei preferiti dell'infanzia...

Esattamente!!
Da wikipedia

The computer graphics for the film were rendered by Digital Productions on a Cray X-MP supercomputer. The company created 27 minutes of effects for the film. This was considered an enormous amount of computer generated imagery at the time.[3] For the 300 scenes containing computer graphics in the film, each frame of the animation contained an average of 250,000 polygons, and had a resolution of 3000 × 5000 36-bit pixels. Digital Productions estimated that using computer animation required only half the time, and one half to one third the cost of traditional special effects. The result was a cost of $14 million for a film that made about $21 million at the box office.[3]
Not all special effects in the film were done with computer animation. The depiction of the Beta unit before it had taken Alex's form was a practical effect, created out of materials and produced on-set. The StarCar driven by Centauri was also a real prop. It was later reused in the film Back to the Future Part II as a car parked on one of the streets in the 2015 future setting.

il Cray usato per il film dovrebbe essere un coso cosi' :




Mi ricorda la poltrona di un negozio di scarpe anni ottanta

è rafreddato a liquido?

cmq, ci gira Crysis sul Cry?

Ecco cos'era sta cosa che c'è al museo della scienza a Londra.

Al limite ci potrebbero girare Craysis e FarCray...comunque per restare in tema, Cray venne acquistata da Sgi, marchio storico della computer grafica cinematografica sulle cui workstation vennero prodotti quasi tutti gli effetti visivi degli anni 90 e primi 2000

e invece qual'è il film che si fregia di primo realizzato con implementazioni di cgi?

[totoro]

su Wiki c'e' segnalato "il mondo dei Robot" filmazzo del 73 con yul brynner nel ruolo del cyborg cattivo, peraltro scritto e diretto da Michael Crichton (r.i.p.).

Il primo personaggio animato in cg 3d è il cavaliere di vetro di "Piramide di paura" (1985), il film sul giovane Sherlock Holmes.
L'animazione è stata fatta da John Lasseter, che adesso è il direttore creativo di Pixar (e anche Disney), a quel tempo Pixar era la divisione CG di Lucasfilms.



La prima sequenza in CG in assoluto invece mi pare fosse all'interno di un film di Star Trek, ma non sono sicuro, devo cercare...

The first feature film to use digital image processing was Westworld, in 1973--the same year as the first SIGGRAPH conference. John Whitney Jr. and Gary Demos at Information International Inc. (III; aka "Triple I") provided digitally processed, pixellated versions of motion photography to portray an android point of view. The same group used digital compositing to materialize characters over a background in the 1976 sequel, Futureworld. These efforts were recognized with a Scientific & Engineering Academy Award in 1994.

In 1977 Star Wars used what was probably the first example of 3D computer graphics in film, albeit in the form of vector or wireframe, rather than shaded, imagery. Larry Cuba, in what was then called the Circle Graphics Habitat (now the Electronic Visualization Laboratory, or EVL) at the University of Illinois at Chicago Circle, created a 3D wireframe view of the trench of the Death Star that was used to train rebel pilots. This film also featured a rare example of analog 3D computer graphics--a very brief, false color image of the Deathstar emerging from behind a planet--created using the Scanimate system.

In 1979 Ridley Scott's Alien was released and made limited, but effective use of 3D computer graphics, again in the form of vector or wireframe graphics. Systems Simulation Ltd. of London created a computer monitor sequence showing a terrain fly-over, rendering computer-generated mountains as wireframe images, with hidden line removal.

The first feature film to use shaded 3D computer graphics imagery, rendered in the style used today, was 1981's Looker. Polygonal models obtained by digitizing a human body were used to render the effects, which were again created at III. After working on the effects for Looker, John Whitney Jr. and Gary Demos were instrumental in the pitching and preproduction of the next big CGI film, Tron, but left III before its production to form Digital Productions.

The film many people associate with the (difficult) birth of Hollywood computer graphics is Disney's Tron, released in 1982. The effects for Tron were created by a number of fledgling production facilities: III, Magi Synthavision, Digital Effects (of New York), and Robert Abel and Associates. Despite its intriguing and attractive imagery, the poor critical and public response to Tron, as a film, together with some delays and difficulties during production, put a chill on the CGI industry that probably slowed its growth for a time. Indeed, most of the CGI production companies involved in Tron are no longer in business and none are currently involved in computer graphics production. All of these companies produced television commercials for a time during the 1980s, and Gary Demos, while still at III, produced some unused and seldom seen but impressive test footage of an X-wing fighter for Star Wars. The polyhedron character, "Bit", in Tron is probably the first CGI "character", though it was deliberately designed to have a sufficiently limited range of controls and animation that it is debatable whether this work qualifies as true character animation.

In 1982 Paramount released Star Trek II: The Wrath of Khan, which contained a one minute CGI sequence depicting a simulation of the birth of a planet (the "Genesis Effect"), created by Pixar, a LucasFilm spin-off that would go on to produce Oscar-winning computer graphics in the years to come. The Genesis Effect made the first onscreen use of a particle rendering system to achieve its fiery effects.

Era la prima sequenza interamente in cg, sempre di lucasfilms/pixar

ad opera di Ed Catmull ora uno dei boss della Pixar, che realizzo' anche gli effetti digitali del seguito del "mondo dei robot", nel '76... questo signore ha si' due cubi (poligonali) al posto dei testicoli...

Se si potesse dare un padre alla computer grafica, sicuramente sarebbe Ed Catmull.
Io ho avuto la fortuna di vederlo dal vivo, dentro la Pixar
Mi è passato dietro mentre indicavo una foto e dicevo "hey, ma quello nella foto è Catmull"

No ma tanto parlavo in italiano (anche se il suo nome l'avrà capito ) e comunque quando mi è stato detto che era dietro di me era gia lontano, non sono riuscito a fermarlo

[sauro82]

Comunque GIOCHI STELLARI è un gran bel film
E' uno dei miei preferiti del genere (ovviamente tra quelli "vintage").

Adesso ci hanno messo una barriera di plestiglass attorno perche' la gente lo usava come panchina

[CYRANO]

ma come potenza di calcolo , quel cray li' a che pc si puo' comparare al giorno d'oggi ?
