Next gen lighting technologies - voxelised, traced, and everything else *spawn*

Well, yes, I also think they ray-trace a 'voxelized' triangle mesh and use the voxels for the empty space skipping during ray-tracing and storing triangles. There is various ways to do this efficiently, but basically per voxel you have a flag that tells it is empty or not empty. In case of a none empty voxel a limited number of triangles (like 1-4) would be associated with that voxel, similar to what marching cubes produces: So instead of BVH, 3D textures are used for accelerating the ray tracing.
Anyway impressive they managed to make it that fast using general purpose compute.

Not sure I understand. While the Infiltrator demo is still amazing, it doesn't have ray tracing tech running - as far as I understand? It certainly doesn't have RT running on compute.

So my question was very much related to how can we have a demo with RT running that well, on compute without RTX? What's stopping anyone from using that in the real world? What am I missing?

 

Yes curious how they achieved anything remotely as good like that without RT hardware on a Vega. It is very close to proper hardware accelerated RT and it is amazing that it manages to run at that framerate even if not butter smooth,
It looks outstanding and very promising.
That infiltrator demo reminded me why I am so disappointed with this gen. What hardware was the Infiltrator demo running on? The quality is beyond anything we could get on current logically priced hardware.
This and the Final Fantasy demo by Square Enix were a hint of what to come and not what was achievable this gen

 

We don't exactly know what is using RT and what isn't, and it can be tricky to distinguish it in a tech demo imo.

 

If this is borrowing off their other dynamic GI technology, and assuming some of the restrictions are still in place, I believe it's still single light source for dynamic GI portion. But in this video, it doesn't look that way. Not sure if there are some limitations like mixing light sources for GI. At least the last time I checked, both Crytek and UE were running single source and usually that meant for most games implementing the technology the single source was the 'Sun'.

Not sure how they did reflections, I'm going to assume with shooting rays.

I guess the big part is whether they can actually be implemented in a game. That's generally been my barometer for these types of things, but this looks promising.

 

How was every Pixar movie (& short) before Monsters University possible without RT?

 

Both the Infiltrator and Agni's Philosophy Final Fantasy tech demos were running on a single GTX 680.

 

On the topic fo GDC - looks like Shadow of The Tomb Raider will finally be releasing their patch soonish.

Topic on their DXR shadowing and point light system

 

Or not (?)..

Yup, The PC running Agni's Philosophy in 2012 had a single GTX 680 which was about ~3 TFlops (Nvidia Kepler architecture) an i7-3770K at 3.5GHz with 32 GB of RAM.

 

So what prevents our consoles from outputting something similar? Is it memory constraints?
I had the impression they had stacked multiple GPUs in one of the presentations

 

lol true enough

 

Unity joins the fray!

 

There was PS4 build of Agni's Philosophy, wasn't there?

 

A lot of it is the need to build an actual practical GAME engine and GAMEPLAY ready assets instead of a tech demo animation.

 

These demos will always have far superior graphics compared to full blown game, you know exactly everything you have to and don't have to render.

 

Yes I understand that with Demos you can pull off more detail since you can focus on what you want to show and everything is under the control of the artists and directors, but still I doubt these visuals can be achieved by our consoles even as tech demos.

 

There you go, running on base PS4
