A user on Reddit recently addressed Infinity Ward’s tech demo for the upcoming Call of Duty: Ghosts, in which the developer stated that it was using Sub D technology for rendering high-polygon models.

According to the user, models created with Sub D use an aggressively high level of polygons which can’t be handled by current gen hardware in real-time. Even if they could be rendered, it would be a waste of resources. Considering the Call of Duty: Ghosts will be coming to the Xbox One and PS4, maybe the Sub D technology is only for next generation platforms (and PC)?

Of all people, an employee from Rare responded to the post stating that, “You certainly can use sub division surfaces in games. At Rare we implemented an engine using sub div surfaces for Perfect Dark Zero – back when we were creating the Gamecube engine, before it got X-Boxed. The reason we eventually went for View Independent Progressive Meshes, was because sub div surfaces destroyed your vertex cache.

“You had to generate new vertices and it destroyed any kind of coherency on your index cache (VIPMs also suffer the last unless platform supports invalid zero area triangles). I assume modern hardware has come a LONG way in this regard. It certain does NOT increase the number of polygons infinitesimally – instead it allows you to generate as many as you need (and can process) at the required level of detail.”

Infinity Ward has been the subject of controversy concerning the “new” engine for Ghosts, when it was revealed that it was only a heavily modified version of the engine that had been used in other Call of Duty games till date. The whole “realistic fish AI that swims away from you” bit didn’t help matters either. But it’s hard to deny that Sub D isn’t a new technology and thus, not worth such a big deal that Infinity Ward has made it out to be.

The trailer is highly inspired by Tron with a mix of Mass Effect including the look, style and the music. A soldier in a white suit uses dual laser blades to fight a horde of computerized monsters in a virtual testing world.

This would be a fantastic setting for a new game; however, it’s highly unlikely that this is a tease of any game at all but rather just a typical tech demo for the PC fans. Despite that this is probably not a game or any sort of new IP it’s still enjoyable, and fun to watch.

GDC is a place where game developers can come together and showcase cool content. Most of them won’t be available to public and will be held inside closed doors but Nvidia has released a cool demo showing the destruction physics.

It’s all in real-time and it’s not from a game. Here’s what the video uploader Matthias Müller-Fischer wrote about it. The demo is running on a GTX 680 at 30 fps.

“We just got our paper “Real Time Dynamic Fracture with Volumetric Approximate Convex Decompositions” which describes the technology behind this demo accepted by Siggraph. Once we have the final approved version of the paper ready, we will put it online.”

This demonstration is impressive and such an implementation in a game would really enhance the overall immersion for gamers. This is not a Physx video, and just showcases one tech.

Lionhead studio’s lead programmer, Ben Sugden has uploaded a tech demo which he showed off at GDC 2011 on Youtube and it looks amazing.

Titled, “Mega Meshes – Modelling, rendering and lighting a world made of 100 billion polygons”, the video shows off a new tech that the studio’s developed for the Xbox 360.

Here’s the word from the dev himself:

“The video shows the results of the mega texturing technology I developed.
The frame rate is really sucky in this capture, I have no idea why. The rendering engine runs at 30hz, but you’ll have to take my word for that!”

He also uploaded another video which shows of some amazing lightning effects, watch it below:

Do let us know what you think of it below.

A guy’s captured Epic Games showcase of their latest Unreal Engine tech demo behind closed doors at GDC 11 and posted it over at youtube.

As you can see, it’ll take quiet sometime before games can be made at this level.

We hope it’s sooner than later.
