Great Water from Open Source Engine (nGENE)

Found this while browsing. Looks incredible to me.

..yes..I have completed some stuff with that engine...very nice but performance is not that high as i expected at that time i used it..I dont know are they changed things now..

Whole engine looks pretty nice. Seems to be a little rough around the edges, but could be a competitor to LE in the near future. Alot of similarities between them, except they use DX instead of OpenGL. And it's open source, which is a plus for it and should cause it to grow quickly. Josh is really good, but crowd sourcing can lead to explosive development under the right conditions. Biggest drawbacks seem to be that it uses FMOD, which isn't free, and PhysX. I like PhysX, but currently the download site for the SDK is down so new people can't get started with it unless they already have a developer account and the SDK.

[Niosop]

Since it's open source it might not be too hard to pull the ocean shader implementation out of it and adapt it for LE. http://ngene.wikidot.com/licensing seems to indicate that it would be permissible to do so.

It does look nice. But i do think josh has some good ideas for water in LE.

Yes the water does look good, couldn't tell much from the stills but the video section is worth a look.

Hi, thanks for positive comments about my engine However, I don't like being considered a potential competitor of LE. It is a very good and complete engine, while what I do I just do in my spare time (I'm not even working for a gamedev company...). Of course I want to make it better and more programmers friendly engine but that's still a long way to go

 

I believe water could be adapted for LE - I'd be more than happy to know that algorithm I came up with is used more commonly so if anyone of you want to do this, do not hesitate. I will be also happy to help if there are any issues - just drop me an email (tomanw@gmail.com). BTW there is an article in which I described the technique used:

You can also visit my blog:

where I describe many useful techniques and algorithms (or at least I hope so ).

Thanks for the offer to share the algorithm Riddlemaster and for the informative links. Your engine does look very nice and the water particularly impressive. I wish you continued success with your engine! It would be nice to see your water techniques implemented with LE.

Is there a compiled example I can view?

You can try this: http://www.mediafire.com/?muom2wz1y3z

 

It's the old demo I used during presentation of the effect. The technique evolved a bit since then but it shows general idea. I know there were some issues on some configurations. If that would be a case just let me know and I'll try to upload updated version.

[Josh]

I'd like to see a newer version if possible. I'm not sure if the demo is just old or not working right, because I ran it on an ATI 3870.

Sorry for lack of response. I'll upload one during the weekend and will let you know here when that's done.

[Riddlemaster]

Ok I uploaded the demo (it's more less the same but a bit simplified). I hope it runs this time, however, I don't know if it is not some Radeon related problem (especially PhysX support). If there will be any problems I'll try to resolve them.

It seems to be compiled in VS2010, and I don't have the runtime. Last time I installed VS2010, it destroyed randomly files on my harddisk, because of a bug in .NET 4.0 Beta 1.

[wh1sp3r]

yes, VS2010 is cool, but really bugged ,lol

[Riddlemaster]

It's compiled in VS 2005.

[Pixel Perfect]

It crashes on my ATI Machine with an unhandled Fatal Error just after loading nodes for the forest. I'll try it on my nVidea PC and report back.

[wh1sp3r]

It'S fine on my ATI card only DirectX10 crashes

[Riddlemaster]

DirectX 10 is WIP (a real, real WIP )

[wh1sp3r]

Riddlemaster: by the way, your water looks very good i like waves + white reflection

[Pixel Perfect]

Yeah, working fine on my nVidea (spec as below). The water and sky effects are both really very good. The HDR seems a bit fierce and I'm getting occasional issues with what might be clipping planes but the water is top notch. I particularly like the foam on the water ... that looks completely natural. The only water I have seen that betters this uses FFT for all those cascaded wave frequencies that make it look totally realistic. Very impressive!

same article i was workin with ^^

just that u got much better results then me...

demo doesnt work with my radeon..

 

if someone can write an glsl code for that:

float3x3 compute_tangent_frame(float3 N, float3 P, float2 UV)
{
float3 dp1 = ddx(P);
float3 dp2 = ddy(P);
float2 duv1 = ddx(UV);
float2 duv2 = ddy(UV);

float3x3 M = float3x3(dp1, dp2, cross(dp1, dp2));
float2x3 inverseM = float2x3( cross( M[1], M[2] ), cross( M[2], M[0] ) );
float3 T = mul(float2(duv1.x, duv2.x), inverseM);
float3 B = mul(float2(duv1.y, duv2.y), inverseM);

return float3x3(normalize(T), normalize(, N);
}

i think i can pretty much provide results like that..

[carlb]

think its a ati bug as they broken a few directx stuff this time round

 

i've already reported a few game that crash that worked witht he older version

Well it's because I'm the author of this article so it was easier for me I guess

 

Ok, so it seems to be ATI related issue... will look into the code (but as far as I remember there were no problems on reference rasterizer)... geez I hate them compatibility problems...
