I would like to have Cascade Shadow mapping.

This would complete a whole shadowrender pipeline having indoor and outdoor.
With this abillity, its useable for everyone(not just indoor lightning).
Less limits, more oportunities, better results^^

I think I would have more fun by implementing the pp-effects first tongue
but let´s see what the others say wink

Recent A7/8 updates (particularly view_check) make it easier to optimise CSM. Also, nice outdoor shadows have been an expectation in games for a while, but SSAO is much newer and still perhaps considered a luxury.

Finally, CSM is much more scalable than SSAO (that is, you can have decent looking shadows on old systems, and then insanely realistic soft-shadows on newer systems -- I've seen how SSAO can be scalable, but the visual cost means it's often not worth it at all, IMHO).

So CSM's where my vote goes laugh

Great shots, btw.

IMO the difference can actually be worth the performance-pics from my about one year old impl:


..but you are probably right, I´ll implement CSM first.

Btw. your tutorial was quite usefull to find a start, Julz wink

Oh yes, it adds huge amounts to a scene! What I meant more was that it (afaik) cannot really be scaled down to run well on older systems while still looking nice. Of course, that depends on what is meant by "older system". But CSM gives you more room to play around and provide a variety of options, I believe (although I have no actual experience with SSAO, so I could be completely wrong).

Cheers grin I look forward to seeing how much you do with it.

I am sure you will win the contest. And besides that I think it would be prudent when Conitec works together with you to make this an integrated part of A8, maybe even integrated in the tool-set. So I hope you get some more compensation for it besides winning the contest prize.

eventually it should be in a suitable form now...
hate..writing...documentation!

There is nothing new in the demo itself except the stuff I mentionied a few posts ago.
There is now a first version of the manual which should help to understand the demo´s code which is not very good commented..
well, actually there arn´t any comments at all^^

Tell me if it´s really that unintelligible, if so I´ll focus much more on that for the contest version.

Here we go:
LightFrog BetaV1 [DOWNLOAD]

Fortunately I´m on vacation next week so I think I should be able to finish the basics.

regards

Nice show of effects.

Although i had some errors.
One effect error, and lost pointers when changing resolution.

For Performance Reasons you should only show the
current "Setup" and blend out the others.
Right now my framerate is at around 17 on the 1024er resolution.

(And You forgot the acknex.dll in the zip)

Very nice,

but you cant use ps_2(at least for ati)
you have to use ps_2b

"Too many arithmetic methods(68),
max allowed: 64 for ps_2"

ok, thx for the information guys.

@Damo: which way did you change the resolution when you got the pointer prob? pressing F5?
Do you know which effect caused the error?
On what system did you run it?

@Rackscha: Which one was the effect with the to high instruction count?
