I like the glass pane shader a lot more.

On a note about the rain though, I would like to see you implement nVidia's texture atlas approach to having realistic rain affected by precalculated rain "lightmaps" which are held in a texture atlas. Their demo was really cool, and I think it would be fun for you to implement. Just a thought.

Looks great but.. The Glass had some black line showing, so I could see it broken into 2 triangles.. I will try upload a picture..

Code: Select all

I Included the Console so you can see the specs....

Link please, by texture atlas do you mean a cubemap atlas? I don't see what lightmaps what to do with raindrops though.

That looks really weird dejai, maybe you should disable the specular or something. I tested this on my ATI 200M, so I'm surprised you DX10 card has problems...

I don't think it is a cubemap atlas. But they use an atlas, I think, that is indexed into by calculating the distance, and angle, and which the rain drop is from the lights. (It does this for every single drop, in the particle system.) I think they also add some reflection and refraction on top of that. Also, I don't think you need to extrude the quads at runtime with the DX10 geometry shader, so I'm sure that could be taken out, and this could be made DX9/OpenGL. But anyways, here are the links:

Video: Rain video
Whitepaper: Rain whitepaper

And it looks pretty d*** realistic.

something wrong with my glass...

Thats the same as Dejai's problem. What video card are you running? (Nice FPS btw.)

PS: Looks like I was the only one that voted for rain drops

Ok, I fixed it. Don't forget to press 1,2,3,4 to check out the colours

i voted drops because every second twit has refraction applied to a plane somewhere in his demo screens

its a generic effect. rain drops are not aAS run of the mill

Holy mother of god this looks amazing.

P.S
I voted for the glass - pretty awesome indeed.

Hmm ...I get Error executing program immediately after clicking on BubbleRefract.exe.

BlindSide · Post by **BlindSide** » Sun Mar 30, 2008 11:45 am

Very odd, can you compile it yourself and see if it works? Source is included

arras · Post by **arras** » Sun Mar 30, 2008 12:11 pm

Yes it is odd.
I 'll will try to compile it later, right now I have something else. I'll report back...

What video card are you running?

geforce 8800 GT

I've got the same weird problem like Virion has but for me the black parts are white.

GFX Card: 1800XT with Catalyst 8.2, i think...

Irrlicht Engine
