computer games with cgi graphics?

[Asenath]

i wonder why for the past 10 years CGI movies looks so good while video game graphics does not match up to the way a movie looks? does it have to do because a game have to hold both coding for the controls function right and hold the data for the maps and how things should look
i always wonder that. movies like Toy Story and a lot of Pixar movies and a lot of Dream Work movies. also do software in making movies uses the same types of features used in games like PhyisX, CUDA etc.and do you guys think video games will reach that kind of graphical detail in our life timesI wonder when someone is going to make computer games with cgi graphics this would be interesting yes?

Because CGI is pre-rendered. It takes months, even years to render it, while video games have to do it on the go.

movies are pre rendered. games cannot be pre-rendered unless you want zero interaction, which would be a movie again.

The most complex scene involved the Driller destroying a computer-generated skyscraper, which took 288 hours per frame.

And keep in mind that this was done with whole farm of render servers and not your one single customer PC.

Pretty much this. When they render a scene in a cgi movie, they start the rendering and hope it's don by the time they get into work the next day. CGI movies just have to play, they don't have to respond to input on the fly or random actions..

And after it's rendered, they fix things up in post, also not possible in games.

Like the others said, every CGI frame in movies is pre-rendered.
You could theoretically do that for games aswell if you had a few dozens hundreds of years free time: just pre-render frame by frame any possible action the ''player'' might want to do. Then you have your game... A bunch of million pictures triggered by you pressing certain buttons. I call that not a very practical solution at the moment.

I don't know about "years." A movie might be in production for years though. Most 3D/CGI movies use rendering farms, a network of a whole bunch of computers. Each computer renders a different part of a scene, pixel by pixel, line by line, and together, they combine the output of every computer to make one fully rendered frame.

I did find one game that is made with cgi graphics but it's a adult game called girfriends forever but think thats the only game.

Yeah, that's probably too much. Still, they don't just render a scene once. They have people or entire teams working on a scene, and they keep changing and improving it until everyone is happy.

It probably takes some time before they run a "serious" rendering of the scene for the first time, but even then it probably goes back into review, to make sure everything looks like they intended it to be.

And there's another difference compared to games: they don't need a generic engine that handles the entire movie in ways that are simple enough for a leveldesigner to set up. They don't need animations to be "formalized" quite as much either, as they can spend a serious amount of time and manpower on pretty much anything.

It's years in terms of "man"-hours, though. IIRC for Ice Age 4 each frame took 5 min to render. So the whole movie is something north of 1.3 years pure rendering time. But the point still stands: it's far too much for a single customer PC to handle.

First: I hate you for making me google it.
This doesn't look like a game at all but a series of movies strung together. Not much different to strip poker games that will play a video loop of your opponents and clips of the stripping.

the closest you get in terms of actual games are Quantic Dream-like games like Beyond: Two Souls or Until Dawn. But having all those different video clips takes up far more space than describing a scene in the game's engine.
