Euclideon Unlimited Detail

Recommended Posts

this was made by Australian Company named Euclideon and it seems to be a revolution in graphic engines

i thought it was kinda awsome so i thought id share since they most likely people with more knowlage about this kinda thing then i have here to have a descusion about it

It’s a scam!

Perhaps you’ve seen the videos about some groundbreaking “unlimited detail” rendering technology? If not, check it out here, then get back to this post:

Well, it is a scam.

They made a voxel renderer, probably based on sparse voxel octrees. That’s cool and all, but.. To quote the video, the island in the video is one km^2. Let’s assume a modest island height of just eight meters, and we end up with 0.008 km^3. At 64 atoms per cubic millimeter (four per millimeter), that is a total of 512 000 000 000 000 000 atoms. If each voxel is made up of one byte of data, that is a total of 512 petabytes of information, or about 170 000 three-terrabyte harddrives full of information. In reality, you will need way more than just one byte of data per voxel to do colors and lighting, and the island is probably way taller than just eight meters, so that estimate is very optimistic.

So obviously, it’s not made up of that many unique voxels.

In the video, you can make up loads of repeated structured, all roughly the same size. Sparse voxel octrees work great for this, as you don’t need to have unique data in each leaf node, but can reference the same data repeatedly (at fixed intervals) with great speed and memory efficiency. This explains how they can have that much data, but it also shows one of the biggest weaknesses of their engine.

Another weakness is that voxels are horrible for doing animation, because there is no current fast algorithms for deforming a voxel cloud based on a skeletal mesh, and if you do keyframe animation, you end up with a LOT of data. It’s possible to rotate, scale and translate individual chunks of voxel data to do simple animation (imagine one chunk for the upper arm, one for the lower, one for the torso, and so on), but it’s not going to look as nice as polygon based animated characters do.

It’s a very pretty and very impressive piece of technology, but they’re carefully avoiding to mention any of the drawbacks, and they’re pretending like what they’re doing is something new and impressive. In reality, it’s been done several times before.

There’s the very impressive looking Atomontage Engine:

Ken Silverman (the guy who wrote the Build engine, used in Duke Nukem 3D) has been working on a voxel engine called Voxlap, which is the basis for Voxelstein 3d:

They’re hyping this as something new and revolutionary because they want funding. It’s a scam. Don’t get excited.

Or, more correctly, get excited about voxels, but not about the snake oil salesmen.

The other notiable problem is ignoring the basis of current 'polygon' technologies like Normalmapping, that have been around for quite some time. Their examples were pathetic and severely lacking. I mean come on, an example of not rendering additional geometry is a single-sided mutant cactus in bulletstorm? Everything they showed in the preview indicated they were doing the same; standard geometry, normal maps, and textures (as opposed to actual lighting).

Convincing a government of burgeoning technologies in the works isn't new, either. :P

am not so sure its a scam as notch says since they were able to convince the austrilian goverment they are the real deal am still intrested in it

i also found this

I am Australian and I can vouch for the technological ineptitude of my government.

They might want the young people's votes. Doesn't matter about the result as long as you're helping the compooter games.

The technology is awesome, and used in several games already but not on the scale they describe, they're clearly bullshitting in that video by the way they poorly describe everything.

Or rather an $84mil filter was cracked in 30 minutes by a 16 year old. My bad.

In conclusion, voxels are a neat but impractical toy, and don't take everything a company says at face value, especially when that company is making millions of dollars in funding.

Artistic Value is a large part of it though, It should be about balanced, a game you're going to spend a lot of time playing, you should be able to appreciate and feel comfortable in. I'm a huge story player, but detail takes a lot of the cake as well.

I still play the old Quake and Unreal games from time to time, and its about as pretty as shit on a shingle but they're gameplay packed. I mean yeah its good games nowdays look good and immersive, but itd be nice if the game itself came first but not if it was gonna take advantage of the latest video cards.

but they put 2 million australian dollers into the compnay you dont do that without research and knowing you ognna get something out of it

if anything that actually shows skepticism. 2 million is generally a very short amount of time in a R&D type situation.
