I all
please test the my version Ambient Occlusion Simulate Shader in the your macchine and post the result

6 FPS on Window Vista / CPU Dual Core 2 Ghz / 2 Go Ram / NVidia 9600M GS


Stevie G(Posted 2008) [#3]
7-8 FPS on WIn XP Pro / Intel Core 2 Duo 2.33 / 2gb Ram / Nvidia 8600gt

0-1 fps, win xp media center. laptop with integrated ati graphics card.


puki(Posted 2008) [#5]
I got 8 FPS on my big-boy rig.

nVidia 8800GTX - Intel Core 2 Duo E6600 @ 2.4GHz.

I bet he left 'Debug mode' on, or he just isn't doing it right - or both.


chwaga(Posted 2008) [#6]
5FPS on Windows Vista, 3Gig RAM, 2.4Ghz Duo Core, Nvidia 9600 GT - 512Mb.

And it looks...odd


Cp(Posted 2008) [#7]
1FPS on Win Vista,2 gig ram,Pentium dual core MOBILE,No Idea what graphics card is


Yahfree(Posted 2008) [#8]
8 fps

9600GT, windows XP, 3GHz P4, 1GB ram

Looks wierd


mtnhome3d(Posted 2008) [#9]
@ cp it sounds like you have an integrated graphics card on your comp.
go to my computer and on the bar under the path text box the should be a button that says "system properties" click it and look on the right for device manager and look for graphics controller.

@ daredevil any chance on a regular old .zip, last time i put win rar on my system it messed up the ability to make zips.


DareDevil(Posted 2008) [#10]
No! the demo no Debug mode, not optimized and this not use shader and is a first test good, for fast speed you reduce interaction this is possible witch KEY button Q/W

the my notebook have a ProSavage athlon 2000
0.82 FPS

for mtnhome3d ok the new test file zip

ok thanks all


Xaron(Posted 2008) [#11]
7.5 fps on a dual core (2.4 GHz) with GeForce 7300 LE and Windows XP, 2GB RAM (yes, crappy environment, it's my office computer) *gg*

Regards - Xaron


_33(Posted 2008) [#12]
I'm waiting for the next optimized version because this one looks odd and is much too slow to be considered practical.


Gabriel(Posted 2008) [#13]
7 FPS on a dual core 2.4ghz with GF 8600 GTS.

I tried more iterations, less iterations, more blur, less blur, but whatever settings I had just gave me a really washed out white screen with the occasional blurred shadowy bits inbetween. It doesn't look like it does in the gallery no matter what settings I put it on.


chwaga(Posted 2008) [#14]
same


Cp(Posted 2008) [#15]
Checked. I think it's an Intel.


mtnhome3d(Posted 2008) [#16]
where is the zip? the link at the top is still a rar? i'd like to test this but can't.

That's pretty much the same picture I get.

Bye


chwaga(Posted 2008) [#20]
still looks pretty freaky...If you want sfx, why don't you just go to another engine??


Stevie G(Posted 2008) [#21]
While I admire your effort - it doesn't look good, it's dog slow so couldn't be put to any practical use in a game. I think you're wasting your time.


mtnhome3d(Posted 2008) [#22]
8 fps, amd turion 64 x2 dual core 1.90 ghz, nvidia geforce 7000, win vista


Gabriel(Posted 2008) [#23]
In addition to what StevieG said, I'm not even sure you're approaching this the right way. You're darkening all the wrong areas. I'm not sure if this due to a misunderstanding in what SSAO actually does if you're trying to overcome an inherent limitation in Blitz3D, but perhaps you could outline in pseudo code or even a plain english description what your code is trying to do.


DareDevil(Posted 2008) [#24]
the system has many errors, but the tests serve in order to verify the speed of this system before continuing

What is Ambient Occlusion used for?


Gabriel(Posted 2008) [#26]
What is Ambient Occlusion used for?

It simulates the way light behaves in reality. Instead of applying a universal amount of ambient light all over a model, it looks for the areas which are least able to receive light ( in others words, the nooks, crannies and crevices where not much light can reach ) and it applies a lower ambient light value in those places than the wide open areas where lots of light can reach. It tends to give a greater sense of depth and "3D-ness" to objects because of that.


mtnhome3d(Posted 2008) [#27]
this is the leadwerks engine performing ambient occlusion.



deps(Posted 2008) [#28]
That was a huge difference! I can see why something like this is useful! :)
Thanks for the explanation.


DareDevil(Posted 2008) [#29]

Stevie G(Posted 2008) [#30]
Has the frame rate improved?


Gabriel(Posted 2008) [#31]
Yes, it's much faster. About 30fps now. I have absolutely no idea what the effect is supposed to be though. It just sort of pulsates between grey and white. It's nothing like it was before, and not what I was expecting it to look like either.


Ked(Posted 2008) [#32]
30FPS without the occlusion.
5FPS with the occlusion.

I kept switching between having it on and off and its pretty much the exact same thing. The difference is that having it on makes it look low res and kinda blurry.

I have absolutely no idea what the effect is supposed to be though. It just sort of pulsates between grey and white.

From what I saw, he has the light moving above the model from left to right and back.


_33(Posted 2008) [#33]
Looks like some low res blurry bloomy overbright effect. Definately eats up too much processing for any practical use.

78fps without
26fps with

Why the fps already is so low without this effect?


DareDevil(Posted 2008) [#34]
the problem is vertical synck i have set Flip(True) and not Flip(False)
this is problem ;)

Bye


Ked(Posted 2008) [#35]
Great!

Post a demo.


Cp(Posted 2008) [#36]
3fps with it


DareDevil(Posted 2008) [#37]

expect the new demo


Ked(Posted 2008) [#38]
There is no difference between that one and the one posted before.

bye all


Stevie G(Posted 2008) [#41]
No offence but 15fps max in such a low res scene is useless.

The high res version looks better but is blurry as hell when moving around.


Cp(Posted 2008) [#42]
hi res:2 fps
low res:3 fps

Not worth it. any larger of a level, and you'd be moving at .0000000001 fps.

I'm surprised people are so hostile to a little experimentation! What's wrong with doing things just out of interest?


_33(Posted 2008) [#46]
True, it could make for a nice pixel blur type effect :P But the framerate would ne to be improved still.


DareDevil(Posted 2008) [#47]
Thanks All

this test is write all in B3D no support C++ :D
