Thanks Elvman.

I'll try to incorporate your new version in my demo and will post new screenshots...

I'm trying to implement this node (good job by the way) into irrlicht but need some help with the decleration in CSceneManager.cpp and CSceneManager.h.
Could someone show me how those functions would be set up in those files, i'd really appreciate it.

And by the way, good job on this node, after I get it setup and running i'll for sure give the author credit!

i think i got a bug, when i have the water against a wall and i looking from behind that wall to the water it reflects the wall in total, over the full length of the water node. The player Y pos is below the water nodes Y pos. so the water reflects only the wall color. instead everything else.

Hi, I have updated the new code in my demo. For me my water look the same as it was. It's still look good.

I still see the problem in the Pixel Shader code. The Fresnel effect is ok, but only if your camera is pointing it's heading a 0 degrees, if the camera rotate left or right, the fresnel effect is wrong. Modified the shader again to show the refraction correctly.

This water node seem only to work for the moment in DIRECTX only, openGL seem to have some problem in the shader code. (My water was black and not moving)

I had made a stupid mistake

last time. Put the water declaration BEFORE the camera definition that made the demo crash because of the GetFOV(); I my previous version, I modified the water node source and declared them manually (Bad because I have a zoom feature in my demo). Simply made the declaration after the camera definition and all is ok now.

Since some people seem to have problem integrating the code in their programs, I've put my adapted working version for Irrlicht 1.3.1 in a linked archive to download.

Also added the updating of the reflection and refraction camera FOV and distance because I had a zoom function in my demo and it was not updated. Now it work perfect.

Here is a link to the modified source: http://www.clavet.org/files/Realistic_WaterCC.zip
I've also put an example code for calling the water node in the archive.
It should work directly in Irrlicht 1.3.1.

A big thank to Evlman for this node. It's really well done.

Can I take some peaces of your code and integrate in the Realistic Water Scene Node (haven't looked at it yet)? I will add your name to the credits.

Thanks Elvman, but you deserve the merit.

I only added 2 lines in "On Animate", (copied the 2 lines to get the camera FOV and Depth that you put in the first declaration.) Now it's updated when animated. That was very simple to do.

For the pixel shader. This is only there waiting that the heading problem that affect the Fresnel effect be fixed. (Hiding most of the fresnel effect while someone found the problem).

The only other things I've done is adapting the code to Irrlicht 1.3.1. and converting the DDS file to PNG. Also put a more detailed example for using your new addons feature that you implemented. (Watercolor)

What version of Irrlicht do you use? It's a tester version?

That was already done in the last version of RWSN

I would like to use this node but when i try i encounter this problem:
GLSL shader failed to compile
ERROR: 0:39: `f`: syntax error parse error
ERROR: 1 compilation errors. No code generated

besides in code fragment

Code: Select all

	WaterSceneNode=SceneManager->addMeshSceneNode(WaterMesh->getMesh(0),this);
WaterMesh->drop();

WaterMesh->drop(); causes program crash (so i hashed it out)

and:
VideoDriver->setClipPlane(0,refractionClipPlane,true);
produces error saying that there is no such method

(so i hashed it out too)

i`m using 1.3.1SkinnedMesh branch and openGL
please help me - i would like to use this beatiful water

I noticed that error i wrote about earlier is caused by float notation eg. 0.5f, i changed it to 0.5 but now i got:
0:62 `-` wrong operand types no peration `-` exists that takes a left-hand operand od type `const int` and rigth operand of type float (or there is no acceptable conversion)
0:62 `*` wrong operand types (yada yada yada)
0:64 `=`: syntax error parse error

i`m really stucked now

please help

Alright, so the node looks Fantastic... I love it, but whenever i add it to the scene, i get a access violation in the device->drop() now. Without the node, no violation... Im pretty sure this type of violation means its looking up a pointer that is already deleted, but i can findout where the problem is. Anyone had similar issues and know how to fix it??

Implementation in main.cpp

Code: Select all

	
	RealisticWaterSceneNode* Water=new RealisticWaterSceneNode(smgr, 10.0f, 10.0f, 
		driver->getTexture("../data/waterbump.png"), device->getTimer());

alterations in RealisticWaterSceneNode.cpp

Code: Select all

scene::IAnimatedMesh* WaterMesh=SceneManager->addHillPlaneMesh("water",Size,core::dimension2d<s32>(10,10));
	
WaterSceneNode=SceneManager->addWaterSurfaceSceneNode(WaterMesh->getMesh(0),1,200,10);
	
	WaterMesh->drop();

Error Breakpoint

Code: Select all

		bool drop()
		{
			_IRR_DEBUG_BREAK_IF(ReferenceCounter <= 0) // someone is doing bad reference counting.

			--ReferenceCounter;
			if (!ReferenceCounter)
			{
				delete this; // <-- Heres the violation
				return true;
			}

			return false;
		}

And quick side note:

If i hash out " // WaterMesh->drop(); " - No access violation, but the D3D9 Debug Spits out:

Code: Select all

Direct3D9: (ERROR) :Memory still allocated!  Alloc count = 136
Direct3D9: (ERROR) :Current Process (pid) = 00001644

Do you get the error just while changing levels or whenever you close down a scene with the RWSceneNode in it?

Posted: **Sun Sep 30, 2007 2:12 am**

someone should adapt the current water surface node to have reflection and refraction qualities

Posted: **Sun Sep 30, 2007 6:04 am**

while change level and next level use real waterscenenode to

if next level didn t use waterscenenode my game no error
