On the PC, this makes for some serious coding challenges. then you might as well have it do something to lighten the GPU load.Д«asically, weвЂ™ve got a two-part asymmetrical job being performed by a two-part asymmetrical pair of workers. And if the CPU is spending a lot of time idle Maybe this is a graphics demo with no physics, sound, AI, caching, or networking going on. polygons and render enough pixels, you will eventually reach the limit of what the GPU and candle. If you push enough static In this context, вЂњstaticвЂќ is just programmer talk for вЂњdoesnвЂ™t changeвЂќ. It depends on how much crap youвЂ™re trying to draw. In any case, this is what weвЂ™re doing when we spend CPU cycles trying to lighten the load of the graphics card. Maybe that was more a pizza analogy than a car analogy, but you get the idea.

He stops cooking and walks a stack of pies out to the end of the driveway so the drivers wonвЂ™t have to drive as far to pick up their pies. But for some reason the cook gets it into his head that heвЂ™s going to вЂњsave some timeвЂќ for his drivers. The cook can just barely cook pies fast enough to keep all the drivers busy making deliveries. This fleet is the graphics card Once of the hallmarks of a really good Terrible Car Analogy is a really complicated metaphor. HeвЂ™s got a fleet of, say, a dozen drivers who each have their own personal jet-powered Batmobile. HeвЂ™s handling the phone, taking orders, counting money, making pies.

WeвЂ™ve got a pizza place at the end of a mile-long driveway. You know what we need? A Terrible Car Analogy: In my very first programming project here on the site, I spent the entire time sorting through polygons and topography, figuring out what parts were worth drawing and what parts could be simplified. The thing is, in the vast majority of cases LOD is something that gets sorted out by the CPU. The system used by Grand Theft Auto IV is going to be very different from the one in Spore, which is again different from the one in World of Warcraft. The trick is that the optimal LOD solution will vary a great deal based on your project. ItвЂ™s a complicated and interesting branch of knowledge. The process of sorting this out is called Level Of Detail.

But this mailbox right beside the camera? That needs to be rendered in full detail.

At this distance it doesnвЂ™t matter how crappy it looks, we just need a little black pole to stand in for the real thing. The street lamp four blocks away? That gets drawn, but weвЂ™re going to draw a crude simplified version of it, probably a simple vertical beam with four sides. The trash cans two miles away? They donвЂ™t even need to be in memory. So the game needs some way of controlling what things get drawn and how detailed they are. I donвЂ™t care how much horsepower you have, how much memory youвЂ™ve got, or how many surfboard-sized graphics cards you glue together and jam inside your PC: Taking all of that clutter for the entire city and hurling it at the graphics hardware would be ruinous. There are literally tens of thousands (maybe even hundreds of thousands) of objects around the city: Street lights, dumpsters, trash cans, newspaper stands, benches, trees, mailboxes, awnings, telephone poles, parking meters, street signs, traffic cones, trash bags, chain-link fences, and jersey barriers.

The most central problem to rendering any wide open space is, вЂњHow do we avoid drawing everything in the entire world?вЂќ You can see this problem at work in open world games like Grand Theft Auto.
