[Solved] Tearing at edges of screen. HydraX 0.5.4 Ogre 1.8.1

Hi,

I've been trying to figure this out for a couple days now and I'm hitting a wall so I thought I'd see if anyone here can help.

Here's a picture of what happens when I move the camera. If I leave the camera stationary then everything looks (somewhat) normal. I think the shaders might be a little off but the water moves correctly and reflects the sky. If I turn the camera to either side the water kind of "tears" like this while I'm turning. Then returns to normal when I'm done.



Here's where things start going wrong in my ogre log.

When I run I am getting these warnings/errors from the compiler. (I am using Visual Studio 2010 express).
'WaterWorldClient.exe': Loaded 'C:\Windows\winsxs\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.7601.17514_none_41e6975e2bd6f2b2\comctl32.dll', Cannot find or open the PDB file

My Hydrax setup in my code.

mHydrax = new Hydrax::Hydrax(mSceneMgr, playerCamera, mWindow->getViewport(0));

// Create our projected grid module
Hydrax::Module::ProjectedGrid* mModule = new Hydrax::Module::ProjectedGrid(
mHydrax,
// Noise module
new Hydrax::Noise::Perlin(/*Generic one*/),
// Base plane
Ogre::Plane(Ogre::Vector3(0,1,0), Ogre::Vector3(0,0,0)),
// Normal mode
Hydrax::MaterialManager::NM_VERTEX,
// Projected grid options
Hydrax::Module::ProjectedGrid::Options(/*264 /*Generic one*/));


// Set our module
mHydrax->setModule(static_cast<Hydrax::Module::Module*>(mModule));

// Load all parameters from config file
mHydrax->loadCfg("Hydrax.hdx");

// Create water
mHydrax->create();

and in my frameRenderingQueued() I update Hydrax.

// update hydrax
mHydrax->update(evt.timeSinceLastFrame);

Thanks in advance for any help you can offer!

Figured it out!

I found someone with a similar problem, I'll quote the response I found there that solved the problem.

Regarding your issues with how the hydrax projected grid is always lagging one frame behind, this is caused by the way Ogre tries to cache node positions and only update them when necessary. Unfortunately it can in some cases result in the derived orientation or position of a node to be incorrect.
Whenever the whole node tree is traversed the correct positions and orientations will be calculated, but unfortunately that traversal happens after the frameStarted events, and thus you get this effect.

I'm guessing that you're moving or reorienting a Node instead of the actual camera. (That's at least how my error was caused.)
The solution as I've found it is to manually call

Code: Select all

theNode->_update(true, false);


after you've moved your node. This will force a recalculation of all derived positions and orientations.
Note that I first tried with calling Node::needUpdate(...) on the affected nodes, but that didn't help.

I added "mynode"->_update(true, false); to update the parent node my camera was attached to.

I called this immediately after my code which involves camera movement. This solved the problem of Hydrax being a step behind my camera node.
