Well right, maybe I stated my point a bit too "black-and-whitish". I'm also biased of the way I usually use this technique.

Well, it's a good technique for how simply and quickly it's implemented that's for sure. I spent quite a long while working on a good impostor system.

Nothing new with me but I have some freetime to continue my lighting manager so I thought I would post a picture.

deferred render (normal & specular mapped)
antialiasing with edges detection (normal & depth)
1 spot light here
variance dual paraboloid shadow mapping (no blur here)
bloom
...

I've done some ssao but I failed to have a nice output I'll redo that.
Next step is to do a nice refraction post process effect with chromatic aberations and put my dual paraboiloid reflexion code into the lighting manager..

If anyone have any idea about a refraction post process effect mainly compatible with a deferred pipeline I would be interested to hear it

So much for me winning this month

Just you wait till i get CSM implemented

Hi folks...

Looong time since my last post hehe. This isn´t really a game project, just something I´ve been working today. A shader for real-time subsurface scaterring simulation. This particular frame was rendered in irrlicht.
I´m working on a fast ambient occlusion implementation, in order to make this shader work for animated characters as well. Hope you like it.

Cool, how did you do the subsurface scattering? Is there a paper you could point me to.

This effect is a cheap hack haha! It works by doing a dot product with the inverted LightDir and the eye vector. I don´t think there is a paper, but there are some slides from a GDC 2011 talk which I cant remember the link right now... sorry

Oh, and you must modulate the scaterring term by the thickness of the model. The original technique does that by painting the thickness on a extra texture map. I´m actually trying to get rid of the extra map by computing it on the fly.

Thanks for explaining it. It looks pretty good for a cheap hack like that, I was planning on using a thickness map anyway.

Each randomly generated world is made of approximately 10 million cubes, which can all be modified. It can run at 100-150 fps on an average computer. It has real-time shadows for all the cubes, and flowing water, with support for multiple players on different computers interacting with the world at the same time.

Hello! You are using occlusion culling?? I trying to show 8 000 blocks without texture and get 8 fps

Rather than using 8000 scene nodes use one which renders all cubes at once.

The cube scene node should not be used for this. It's only for testing purpose.

Have you tested the Hardware Instancing ?

A forum member for so long now and never participated in this contest. Here's my first try with a shot of a concept project.

I'm working with irrlicht about 3 weeks. Please tell me how it works and how to release it? Thanks!

Please keep these questions in your thread in the other forums. This thread here is just for the contest
