Water not visible

After some tweaking and a few choice swear words, I was able to get Hydrax to load in my game. It is actually running calculations because in debug mode the performance is terrrible whenever I enable it, however I cannot actually see the water. It is probably something very simple that I am overlooking due to my lack of sleep as of late. Can anyone see anything that I am doing incorrectly?

The code is the initialization for my player camera that follows the node passed in.


void PlayerCamera::Initialize(Ogre::SceneNode *inFocusNode){
focusNode = inFocusNode;

cameraCollisionMgr = Ogre::Singleton<GameCollisionManager>::getSingletonPtr();
cameraCollisionMgr->setSceneManager("Play");

//At least for now, this variable equals:
//cameraNodeName = MyPlayerCam
Ogre::String cameraNodeName = inFocusNode->getName()+ "Cam";

parentNode = Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getSceneManager("Play")->createSceneNode(cameraNodeName + "parent");
//create the camera node

node = parentNode->createChildSceneNode(cameraNodeName);

//create the camera
myCamera = Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getSceneManager("Play")->createCamera(cameraNodeName);

//put set viewport to this camera
Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getAutoCreatedWindow()->getViewport(1)->setCamera(myCamera);

//attach cam to node
node->setPosition( Ogre::Vector3(0, 0, -400));
node->rotate(Ogre::Vector3(0,1,0), Ogre::Degree(180));
node->attachObject(myCamera);

//myCamera->setAutoTracking(true,focusNode,Ogre::Vector3(0,50,0));
node->setAutoTracking(true, parentNode, Ogre::Vector3::NEGATIVE_UNIT_Z, Ogre::Vector3(0, 0, 0));

cameraRaySceneQuery = Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getSceneManager("Play")->createRayQuery(Ogre::Ray());
cameraRaySceneQuery->setSortByDistance(true);

//camera starting values
direction = Ogre::Vector3::ZERO;
rotate = 0.13;
move = 200;
cameraOffset = 400;
myCamera->setNearClipDistance(0.1);

// Create Hydrax object
mHydrax = new Hydrax::Hydrax(Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getSceneManager("Play"), myCamera,
Ogre::Singleton<Ogre::Root>::getSingletonPtr()->getAutoCreatedWindow()->getViewport(1));

mHydrax->setModule(static_cast<Hydrax::Module::Module*>(new Hydrax::Module::ProjectedGrid(// Hydrax parent pointer
mHydrax,
// Noise module
new Hydrax::Noise::Perlin(),
// Base plane
Ogre::Plane(Ogre::Vector3(0,1,0), Ogre::Vector3(0,0,0)),
// Normal mode
Hydrax::MaterialManager::NM_VERTEX,
// Projected grid options (Can be updated each frame -> setOptions(...))
Hydrax::Module::ProjectedGrid::Options(/* Default constructor */))));

mHydrax->setComponents(
static_cast<Hydrax::HydraxComponent>(Hydrax::HYDRAX_COMPONENT_SUN |
Hydrax::HYDRAX_COMPONENT_FOAM |
Hydrax::HYDRAX_COMPONENT_DEPTH |
Hydrax::HYDRAX_COMPONENT_SMOOTH |
Hydrax::HYDRAX_COMPONENT_CAUSTICS |
Hydrax::HYDRAX_COMPONENT_UNDERWATER |
Hydrax::HYDRAX_COMPONENT_UNDERWATER_REFLECTIONS |
Hydrax::HYDRAX_COMPONENT_UNDERWATER_GODRAYS));

mHydrax->create();

bool PlayerCamera::frameStarted(const Ogre::FrameEvent& evt){
//translate camera to keep up with player
//node->setPosition( Ogre::Vector3(node->getPosition().x, 50, -cameraOffset));

mHydrax->update(evt.timeSinceLastFrame);

parentNode->setPosition(focusNode->getPosition() + Ogre::Vector3(0,50,0));
node->needUpdate(true);
cameraGroundCollisionCheck();

return true;
}

Update: I can put my camera under the water plane and get the effect of being under water, I just simply cannot see the top of the water

Try running with disabled shadows.

This worked! Thanks!

Is there any way to have shadows and Hydrax running at the same time?

Yes. I think it's something about the correct loading order. Try loading Hydrax then setting shadow and vice versa - one should do.

If you are using stencil shadows then you will run into problems with hydrax. To get shadows working you have to use texture shadows.

eg:

mSceneMgr->setShadowTechnique(SHADOWTYPE_TEXTURE_ADDITIVE);
etc...



Angus

I had the same question.But I dont know how could I disabled shadows?
the Entity's Shadow with setcastshow()?

mSceneMgr->setShadowTechnique(Ogre::SHADOWTYPE_NONE);

mSceneMgr->setShadowTechnique(Ogre::SHADOWTYPE_NONE);
I try put this sentence almost everywhere,but I still can't see the water above the water plane.
I use PagedGeometry render trees and grasses,does this plugin incompatible with hydrax?
