and of course it worked perfectly once I added other items. Thanks for the scenenode, it really looks nice!

I am really glad to hear that.

This does not work with multiple cameras.
I have a FPS camera and a static camera view from from the top (like a map view) in a small area in the top right corner.
This works perfectly in OpenGL.

However when I add a RealisticWaterSceneNode to the scene the top camera fills the screen and my map on/off shortcut just lets me switch between those two cameras. I am no longer able to show both views at the same time.

Any ideas?

There seems to be another problem.

If I have a scene with just a skydome and water and look straight ahead, everything looks fine. If i start to lower my camera angle, I would expect to see more and more blue water. This happens but the water turns darker and darker as the angle gets lower and lower.

Adding more and more objects to the scene helps but the error is still there it's just not that much visible anymore.
The scene uses ambient lighting.

Minor update: removed timer parameter from constructor.

Now working on multiple view bug fix. Thanks for submissions.

Is there something more to edit in the code than just taking away the timer parameter from RealisticWaterSceneNode creation???

in version 19 I used to have:

Code: Select all

myRiverNode = new RealisticWaterSceneNode(smgr, 10000, 10000, 
		driver->getTexture("media/textures/water.jpg"), device->getTimer());
...

with this new version, just took away the timer parameter:

Code: Select all

myRiverNode = new RealisticWaterSceneNode(smgr, 10000, 10000, 
		driver->getTexture("media/textures/water.jpg"));
...

Now the water doesn't show.

And another question, I remember the demo that came with this shader (and thanks for the shader) using Irrlicht 1.4 or 1.5 and it got that crystal clear water, with version 19 I cannot get it, reflection works great, but the water is not transparent, it looks like liquid metal or something like that, here I show it:

And the same with water node's visible set to false, so bottom distance can be apreciated:

Thanks!!!

Can you post a screenshot with camera looking at water (about 90 degrees)?

If my configuration is important, my netbook:
Intel Core 2 Duo
GeForce 8600M GT

Code: Select all

device = createDevice(EDT_OPENGL, //driver
						  screenres,//screen resolution
						  32, //BPP
						  false, //fullscreen
						  true, //stencil shadows
						  false, // vsync
						  0); //event receiver

Thanks for your time.

Ok, it seems that there are problems with the shader. Do you get any irrlicht warning generated by shader? And can you post some code (where you create the water scene node) and what objects do you have on scene?

I just saw this new release and quickly tried it.
However using just the basics, terrain, skydome and water (simplest possible).
The water simply doesn't show, but the bumpMap is loaded. Same problem with D3D and OGL, but gl says unsupported texture format three times.

I guess the shader is buggered, but I'll have to leave that to someone else here since I should be busy elsewhere right now.

No warnings about shader, water creation code:

Code: Select all

myRiverNode = new RealisticWaterSceneNode(smgr, 10000, 10000, 
		driver->getTexture("media/textures/water.jpg"), device->getTimer());
		
		if(myRiverNode)
		{
			myRiverNode->setWindForce(10.5f);
			myRiverNode->setPosition(vector3df(15000.0f,80.0f,0.0f));
			myRiverNode->setMaterialFlag(EMF_LIGHTING, false);
			myRiverNode->setMaterialType(EMT_TRANSPARENT_ADD_COLOR);
			myRiverNode->setMaterialFlag(EMF_FOG_ENABLE, false);
		}

Before water creation I have 3 nodes:
2 IAnimatedMeshSceneNode (character .X, and weapon .OBJ) with shadowvolume and lighting on, fog off.

1 ITerrainSceneNode with lighting on, fog off.

After water creation:
1 skydome node:

Code: Select all

driver->setTextureCreationFlag(video::ETCF_CREATE_MIP_MAPS, false);
scene::ISceneNode* skydome=smgr->addSkyDomeSceneNode(driver->getTexture("media/textures/skydome.jpg"),16,8,0.95f,2.0f);
driver->setTextureCreationFlag(video::ETCF_CREATE_MIP_MAPS, true);

1 light:

Code: Select all

smgr->addLightSceneNode(0, vector3df(0, 15000, 2000),SColorf(0.1, 1, 1), 20000.0f, -1);

1 camera node:

Code: Select all

cam = smgr->addCameraSceneNode(0, vector3df(1800, 3800, -700), vector3df(0,3000,2000));
		cam->setNearValue(1.0f);
		cam->setFarValue(1000000.0f);
		cam->setPosition(vector3df(0,2000,-1500));

In the game loop just manage eventReceiver to control character position or exit, change character position and animation frame loop, change camera position relatively to character position.

Render with:

Code: Select all

driver->beginScene(true, true, SColor(255, 100, 100, 100));
smgr->drawAll();
driver->endScene();

Versions:
irrlicht 1.7.1 Professional (Build 7600)
RealisticWater 019
OpenGL 3.3.0
GLSL 3.3
IDE Visual Studio 2008 (C++)

PD: Under DIRECT3D9 the shader doesn't compile:

Code: Select all

HLSL pixel shader compilation failed:
(68): error X4523: cannot map this dependent texture read to ps_1_1
(63): error X4523: cannot map this dependent texture read to ps_1_1

HLSL vertex shader compilation failed:
(1): error X3000: syntax error: unexpected token 'vec2'

And Thanks again for your time,

Surface water ~ On Object~

but... Camera position move... It is stange render .

What is the problem?...

Can you change the line 36 of realistic vater scene node (EVST_VS_1_1) to use VS version 2.0 and do the same for PS (line 37)?
I guess there is a problem with vertex and pixel shader versions.

HLSL vertex shader compilation failed:
(1): error X3000: syntax error: unexpected token 'vec2'

This error is strange. There are no vec2's in HLSL shaders.

Changing those lines change nothing visualy, I proved with every combination of EVST_VS and EPST_PS versions.

I was taking a look to the shader example that comes with Irrlicht (because I remembered about that example having a transparent cube), and I added EMT_TRANSPARENT_ADD_COLOR to addHighLevelShaderMaterialFromFiles function, with that I get a transparent water, but it is too transparent

This is the change in code (RealisticWater.cpp line 35):

Code: Select all

_shaderMaterial = GPUProgrammingServices->addHighLevelShaderMaterialFromFiles(
		waterVertexShader.c_str(), "main", video::EVST_VS_1_1,
		waterPixelShader.c_str(), "main", video::EPST_PS_1_1,
		this);

To

Code: Select all

_shaderMaterial = GPUProgrammingServices->addHighLevelShaderMaterialFromFiles(
		waterVertexShader.c_str(), "main", video::EVST_VS_1_1,
		waterPixelShader.c_str(), "main", video::EPST_PS_1_1,
		this,video::EMT_TRANSPARENT_ADD_COLOR);

And this is how it looks now:

The only problem I see is that is too transparent and it doesn't look good (from my point of view) when I try to simulate the night, or maybe it must looks that way, just I don't know it (I haven't see to much water on night time), maybe when I add more objects around it will look better, anyway I'm very very happy with the results that the RealisticWaterSceneNode gives.

This is how it looks:

Thanks again for taking your time to help!!!

You made water transparent by using its alpha value. That is not the result wanted. I will try to search for other problems.
