New Water For IRRLICHT Works Good

katoun · Post by **katoun** » Wed Apr 13, 2005 6:23 pm

Hello
For start the sourse info comes from:
http://collective.valve-erc.com/index.p ... simulation
At first time , the second nad the third time you see the formula you just say "It is not for me I wont do that in a million years", but I did it and I'm so happy.
For the water that simulates a river, in my quest for info about real time water simulation I have found some interesting code .
That code simulates 3 tipes of water :
-one bihaves similar to mine but is totaly diferent(and I have tried to make that work in Irrlicht but it diden't what to at all)
-one is a sort of water bloed by wind
-one is an 'statistical water' that produces waves like the ones on the sea(those
I must say that I read are generated with turbulence formulas with Fast Fourie Transformations(but I dont have any clue haw is that make ).
Ah and that engine could be fount here:
http://gchen.sdf-eu.org/Chengine/Pages/Diary.htm

An other very nice info page is:
http://www.vterrain.org/Water/index.html

So who can make caustics for the water and ofcourse a nice water material
Ah and who could add for Irrlicht Cube Mapping

There are so many thing I would add to Irrlicht but I just can't make them all

Curently I'm adding to Irrlicht0.9 source some features that are in IrrlichtNX without changing it ( just adding mostely,like spot light, skydome, a loading bar in the Gui added by me,anisotropic filter added my me, today I shall add md3...)
If someone interested in somthing like this, we could continue a project like IrrlichtNX but something more like Irrlicht-Spintz(adding features paches, maby some propertary format, so we can load in the games meshes with LOD ....)

etcaptor:
about:
IAnimatedMesh* animatedMesh =CGeometryCreator::createHillPlaneMesh(.....
well that was my first option and it compiles and at run time I get an 'could not read memory at bla bla....' error.
It seems that by calling scenemenager's function a funtion it is called inside smgr:

Code: Select all

IAnimatedMesh* animatedMesh = CGeometryCreator::createHillPlaneMesh(tileSize, 
		tileCount, material, hillHeight, countHills, textureRepeatCount);

	addMesh(name, animatedMesh);<----------------that function

	animatedMesh->drop();

Code: Select all

//! adds a mesh to the list
void CSceneManager::addMesh(const c8* filename, IAnimatedMesh* mesh)
{
	mesh->grab();

	MeshEntry e;
	e.Mesh = mesh;
	e.Name = filename;
	e.Name.make_lower();

	Meshes.push_back(e);
}

that might be the problem(it seamed that for me it did)

Katoun, I am interested in seeing a binary example of your work, can you provide one (or can you, Alvaro)? I will be taking a look at the code, and seeing how it was done and possibly (if I can) make some improvements. I also want to add refraction/reflection shaders for the water, possibly as bools in the water creation scene node, or even a material type (for example water->setMaterialType(EMT_REFRACTION)). But, can I please see a binary?

Thanks

Oh that's good(with the refraction material)
About the binary, do you have an email I could send it that way to you(and the latest one-I mean the Water Demo and the code because I have made some little modifiaction)

Here is the little modification of the code:

Code: Select all

void CWaterSurfaceSceneNode::hitWater(u32 x,u32 y,f32 depth)
{
	if((x<=0 || x>=m_tileCount.Width*m_Size) || (y<=0 || y>=m_tileCount.Height*m_Size))
		return;
	currentPos = (currentPos + 1) % 3 ;
		
	core::array2D<f32> pos0(mPosition[currentPos], m_tileCount.Height, m_tileCount.Width);
	
	//pos0(x,y)-= depth*0.2f;

#define HIT(addx,addy) { \
	float Y = floor(y/m_Size)+addy; \
	float X = floor(x/m_Size)+addx; \
	float power = mu/d ; \
	pos0((u32)X,(u32)Y) -= depth*power;  \
	
} /* #define */
	HIT(0,0);
	HIT(0,1);
	HIT(1,0);
	HIT(1,1);
#undef HIT	
	
	
}

Hello
Idea:
Isn't the water somthing like an terrain but an animated one?!
So we can have

LOD for the water made the same way as for the terrain!

Sory, the above guest was me.
When I posted that message I was at school(University).

Katoun, you can send it to me at mike.ennen[AT]gmail[DOT]com

katoun · Post by **katoun** » Thu Apr 14, 2005 10:59 pm

OK
But be aware that the Irrlicht.dll I'll send you has some other implementations(look at my postes above- that is so because I don't have a binary with the water in the original form of Irrlicht ,sorry but it's mostly tha same).

It seems that there was a problem sending the mail:
I got a Mail Send Error saing that it couln't sand the message to mike.enneatgmaildotcom and mu Firefox went 'crazy' when I opened that failure message it allmoust crashed my windows .

I think there is a big problem with Yahoo servers right now I'll try later.

Just to note, your missing an "n" at the end of ennen.

katoun · Post by **katoun** » Fri Apr 15, 2005 7:56 am

Just in the post I forgot an 'n' ,
but the mail I sent was right(I looked at the messages sent list and it is corect)
I'll try now again.

katoun · Post by **katoun** » Fri Apr 15, 2005 8:15 am

Sory it dosen't work.

Look at a part of the failure message I get:

Idea:
Make an yahoo acount, get Yahoo Messanger and tell me from witch to wicht hour you'll try to be conected and if I get you online I'll send it to you that way.(I have tyed to add to the msn and I got disconected.Funny huh.
