Glass Pane and Rain Drop refraction demo - Source Included

[MasterGod]

Maybe you should all just update your drivers cause my specs are little below Virion's and it runs fines for me..

[benny53]

I don't think its the drivers, I have the latest driver for my 8800gts from nvidia. Oh, and I'm getting the black lines and what not as well. The rain drops act fine though.

[xDan]

Wow, a shader from BlindSide that actually runs on my old laptop :P

Those rain drops would look nice dripping down the glass plane!

Yes that was the original plan, expect to see something like this soon

@Everyone with problems, I'm sure I already fixed those problems, maybe you are downloading a cached version from the ftp or something? Can you try downloading again Virion and see if it works.

Make sure that line 40 of "GlassP.glsl" is:

Code: Select all

spec = clamp(pow(spec,16.0),0.0,1.0);

BTW: Has anyone actually tried/read the tutorial? I spent some effort commenting the code and making it easy to understand.

PS: Who thinks the raindrops look better like this?



To try it change line 23 of DropP.glsl to:

Code: Select all

projCoord.xy += ((TexOff.xy - vec2(0.5,0.5)) / 5.0);

I was going to have a look at it when I get more time, and XEffects. But to be honest, I have been very busy lately, and cannot do anything programming related.

I do like the fact that you took the time to comment it out though, kudos.

[jingquan]

Yes I did read it, good job. Close to 200fps on my ATI 3850 looking at the glass plane. I didn't knew there was a bug with setting particles visibility, thought my code was malfunctioning...Anyway, nice thinking with the alpha trick.

Too bad it's another scene.render() that made me drop glass rendering.

But it sure does look pretty doesn't it? Maybe you can enable it only for high settings. I mean theres always gonna be someone with a 8800GTS that can run your game way too fast anyway.

Blindside you're my hero :p
This looks amazing

[BlindSide]

Ok this last update should fix it on most machines. Can anyone thats been having trouble download it again and see if it works correctly now?

@Arras: Oh yeah I just realised this ones dynamically runtimed so you need the MSVC 2005 Runtime pack (Yes it crashes sometimes without it, Microsoft, go figure eh ).

[BlindSide]

Did anyone try sticking an animated mesh in there? :





I've updated the executable and the source to include this

[FuzzYspo0N]

i actually laughed out loud. u and that dwarf blinside... one of these days.

It looks awesome though. well played

[agi_shi]

Looks very nice, good job!

Just a little nitpick (you've probably seen this already, though), you'll need a custom clipping plane (especially with large objects; rain drops don't artifact too badly). Otherwise, you'll get ghost refractions from occluders in the frame buffer (same concept as reflection/refraction/portals). Just shear the near clip plane before rendering to the rtt, or take advantage of today's cards user clip planes.

[BlindSide]

Yep, well spotted agi_shi. I was thinking of adding a clip plane to the glass pane's refraction but I figured its going a bit far for this tutorial (And I also hear that something is wrong with Irrlicht's classifyPointRelation function for plane3df (I think), so I would have to use my own methods to calculate which side of the glass the viewer is on).

Cheers

running very nicely on linux 30fps on a GF6200LE
i can't wait to see the progress of u'r water demo and the metaball demo.

[JDHunter]

Hey BlindSide,

thx for nice tutorial, very nice work...
very helpful... big thx for release the source

currently successful tested on laptop with a Radeon XPRESS200 SERIES 8FPS, all shader run correctly

later i will test it on 8800gts
