AMD Radeon HD 7900 series "Leo" tech demo

AMD Radeon HD 7900 series DirectX 11 tech demo that demonstrates the rendering of complex lighting that would normally require a deferred rendering path for reasonable performance, in a forward renderer, thus maintaining universal hardware MSAA support and proper alpha blending support. This technique also supports one bounce global illumination effects by spawning virtual point light sources where light strikes a surface.

I say: "Wow, look the cool new technic for real time rendering..."

Girlfriend says: "Did you see the cute Dragon??????"

@SiriusTexra The demo is a proof-of-concept technology, with the aim to demonstrate certain rendering methods at run-time.The two main points here are the use of hardware managed virtual texturing (PRT) and forward rendering pipeline with compute shader based light occlusion, that allows application of hardware MSAA by avoiding the pitfalls of the deferred rendering.

This demo is very funny!I like it!

But it is still incomparable to the ones made by nVidia.I mean,when you see this one and Nvidia's Medusa demo, which is three or four years old,you must admit Medusa is better.

But I will always use Radeon card.

The sad thing is me trying to watch this video on a atom netbook lags...

@Jonesck1 Plausible < Spectacular

@machadophx Ummm, last generation? LOL. The description clearly says they're using a forward rendered avoiding the pitfalls of using deffered rendering (Aka what was used in BF3 and Crysis 2) yet performance is still plausible. The purpose of a tech demo is to show off a specific aspect, not necessarily Wow you with God rays or uber realistic visuals. Look up Screen-space Sub-surface scattering for an idea on what next gen might look like when it comes to lighting.

nice but i hope it's only artistic style that wood (wall, desk, camera) looks so plasctic

If you really want to see powerful graphics that may run in the PS4/XBOX 720 , then search "Fast Global Illumination Baking via Ray-Bundles" on youtube. It's the Luminous Engine that Square Enix is working on.

The uploader (traktamente) has more videos on the Luminous Engine on his channel. Go see them!

I'm tempted to think a Dreamcast could render this rather simple scene albeit at a lower res.

Video edited with Adobe Premiere Pro?

@TheCormocodran But i still think that is so far of the next generation graphics.
