Iridium Screenshots

Here are the latest screens of a simple test level I made being rendered with my Iridium Engine and the A7 engine. All lighting is 100% dynamic and requires no pre-calculations of any kind.

There is also no constants used in rendering - for example, the areas of shadows that are brighter or darker are calculated in real-time based on real-time radiosity lighting from the sun.

You can also see physical volumetric lighting and HDR tonemapping with automatic exposure control.

The demo runs at 120 fps at 1024x1024 resolution on my machine (see my signature for details).

oh, and I'm aware that the shadows and bump mapping suck - I didn't bother blurring them or adding real bump mapping because I was only focusing on the global illumination for this demo. There is also no specular term.

Oh, I forgot to mention two things:
First, the first two screenshots don't have volumetric lighting so you can see the GI more easily.
Second, this is taking MUCH longer to add a user interface then I expected but I will try to get this out asap. I'll make it so you can load your own map, add and move entities, change lighting parameters, change graphics settings (for slower machines), and also make paths for the camera so you can sort of make a "4d movie" to show your friends and enjoy yourself =]

Later I'll add the code I made for everything else like SSAO and dynamic lights other than the sun for the final version.

would be cool to see it with the correct shadows.. generally it looks nice but the system specs are quite high i think

agreed, although you can always run it in lower quality on slower GPUs
Minimum requirements are 32MB graphics card and Intel Pentium 3 CPU.
Minimum req for dynamic Global illumination is a 256MB graphics card - 8800GT is recomended

looks great, the effects such as volumetric lighting and gi are subtle which is a nice change compared to other demos ive seen and your old demo, where it is usually way overdone.

btw, everytime i look at your signature I start drooling...

Looks good, but the shadow resolution looks VERY low, even close to the camera in such a small level. And I wonder if the shadow edges are moving, as that would make them look a lot worse in realtime, but I guess that you are just using a static view for the lights depthmap?

You by the way should be carefull with praising your work, I mean if it is as aswome as you tell us, then great, but so far you weren´t able to show us anything which really reaches that quality.
And I thought that using the better looking and faster than in crysis shadows (I know that I am exaggerating it) is just a matter of one line of code? Thus, why don´t you then just use them? If your answer to that is, that you are improving your engine all the time, then great, but then you also shouldn´t praise it to be better than it actually is at its current state.
That is just what I actually think, but please don´t take it as an offense, as it isn´t meant to be offensive.

At least the overal lighting in your scene looks pretty cool, although a bit too foggy on the last three screenshots for my taste.

Looks awesome, but what's with the shadows?

I like the light distribution in the inside of the house.
The shadows in the outdoor scene are too dark for such a bright day. Some ambient light might solve this.

The GI looks subtle but good.

hmmmkayyyy, now THAT´s a resolution nobody would run a game with -.-
Why dont showing us screenshots in a more common res like 1680x1050 that would give us a sense of how fast it REALLY is wink

sorry, but the shadows are really really bad!

you want to tell us they are like in crysis? - do you really think they look like this:

but that's my opinion...
