Free Radical (Deferred rendering engine)

[ali-rahimi]

Me and Christopher Schiefer are working on this full deferred rendering engine for a long time. We ended up with some interesting results in terms of performance & quality. What you see here is all wip. All Codes are from scratch,none of them is from act3D. We made a huge effort to set it up as optimized as possible. It took us 1 year and yet long a way to go. All post process shaders are downsampled, so it runs very fast @ 1080p.

.... and alot more.
Everything is Optimized due to Downsampling and mostly usage of LUTs for Storing Multiple used calculations

D&F = downsampled and Fullscreen possibility

The rest including deferred pipeline setup, Terrain, etc is mine.

Looks great!

[ShoT]

Badass!!! Hows it running?

[megalmn2000]

Looks very interesting. Is it like a game engine(UDK) or a model viwer (Marmoset Toolbag)?

[Havoc89]

Very sweet. Though the AO seems to be more of a cavity map effect where it highlights edges, darkens corners, while the non occluded surface is sorta washed out. Other then the AO pass, this is fantastic.

Wow guys, great work!
Put a link to your dev site in your signature.
Thanks for posting this so we can have a look see. Top row plug for you. Dont forget to keep us in the loop so we can follow your development.

Cheers.

Thanks guys.
Main purpose of this engine is for my game, but depending on our time we have some cool idea's. One of them is a kinds of social network but only for 3d artist, Imagine a kinds of city, each user have its own home or portal entry, and he or she can present his works on his own space and others can came and visit his place, chatting, writing comments on his 3d wall, etc.There are many 3d social network on the web,
3D Virtual Worlds List
but they all have a stone age graphic and their purpose is different.
What do you think about such a network? any idea?
one of my mates already finished a 3d chat system and networking side for quest3d. So this is a very close possibility, The only issue is time. building such a network + editor is a huge task.

btw, Most of the vegetation are imported from crysis, also Cathedral & Cemetery are from a model pack which i buy it long time ago. And that skin mesh character is from oblivion. Cause these are all test and i will not publish any exe of this environment setup i did not mention those. For a final release everything will be original, just like my other projects.

Pipeline (Old shot)


Our ssao is just like crysis. I just did not adjust its intensity in a proper way. Yet wip.

A Simple and Practical Approach to SSAO

Screen Space Ambient Occlusion in Crysis

Terrain Ambient Occlusion - 2. Sandbox Manual - Crysis 2 Mod SDK - Documentation

Sure we will keep you update, and at some point we need beta tester's before the official release. Just want to know your opinion and suggestion's about such a 3d network, Its very important for me.

There was a really good, in-depth paper on SSAO in the newest Toy Story game.

[yo momy ha]

looks awsome keep it up.

[Polycruncher]

Awesome programming. I think the idea about the 3d world for games artists is a pretty cool idea! It's not the biggest audience, but I would give it a shot.
