[Solved] v2-2 ParticleSystem stall

[dermont]

GL3/Linux/Nvidia.

I've recently updated to latest v2-2 branch to try out the updates for TextureGpu::copyTo.

The scene contains a v1 particle system. Since updating the render pipeline stalls/hangs after a few frames,
remove the particle system everything renders OK.

Previously I started with trying to create a screenshot for a RTT with Image2.convertFromTexture where the scene
contained a v1 particle system. Image2.convertFromTexture only appears to handle certain pixel formats/textures.

What would be the correct way to create a screenshot for a RTT/RenderWindow?

I asked before regarding the copy ctor for Image2, is this correct.

Code: Select all

Image2( const Image &img );

I'm not sure I understand.

Are you asking how to save an RTT to disk? (TextureGpu::writeContentsToFile)
Or are you asking how to efficiently save a sequence of images (like a video) by continously downloading the RTT to CPU every frame?

Edit:

Previously I started with trying to create a screenshot for a RTT with Image2.convertFromTexture where the scene
contained a v1 particle system. Image2.convertFromTexture only appears to handle certain pixel formats/textures.

What do you mean by this? It should be handling all types of formats and resolutions? (anything else is a bug).
Note however, saving it to a disk may pose compatibility issues (for example, saving a PFG_RGBA16_FLOAT to PNG will fail because the file format doesn't support such format, and the file formats that could support it are in codecs that haven't been ported yet)

[dark_sylinc]

If it's the latter (efficiently save a sequence of images (like a video) by continously downloading the RTT to CPU every frame), then you need to do what Image2::convertFromTexture does, however:

• There's no need to call texture->waitForData if it's a RenderTexture
• Image2 creates an AsyncTextureTicket, calls download, then immediately proceeds to map the async ticket. This causes a stall.
• To prevent the stall, you need to create 2/3 tickets (double buffer / triple buffer) which you'll keep forever around. You call download() with accurateTracking set to false at frame N, and call map/unmap at frame N+3. This way you can keep continuously downloading the RTT results without stalling (at N+3, canMapMoreThanOneSlice should be returning false) but the results will be lagging 2-3 frames behind. The limiting factor could become the bus bandwidth or much more likely the disk write speed (if you save the contents to file). You only need to destroy these tickets if the RTT gets resized, you're done capturing, or you're closing the application.

Cheers.

Yes like writeContentsToFile, I didn't see that method. This was my code as a starting point. I first tested RTT

class ScreenShotTextureGpuListener: public Ogre::TextureGpuListener
{
public:
ScreenShotTextureGpuListener() : Ogre::TextureGpuListener()
{

}
static void saveToFile( TextureGpu *texture, const Ogre::String& name )
{
if (texture->getResidencyStatus() == Ogre::GpuResidency::Resident) {
Ogre::Image2 image2;
image2.convertFromTexture(texture , 0,0);
image2.save(name,0,0);
}
}
// for textures with listeners
void notifyTextureChanged( TextureGpu *texture, TextureGpuListener::Reason reason )
{
if (reason == Ogre::TextureGpuListener::Reason::ReadyForDisplay)
{
ScreenShotTextureGpuListener::saveToFile(texture, "TEST.png");
texture->removeListener(this);
}
}

This the what the renderwindow looks like:

This is the screenshot/output from "saveToFile"

[dermont]

Just tried "writeContentsToFile" with Workspace->getFinalTarget() and a RTT texture, both saved correctly. There must have been something wrong in my code, sorry for the noise.

I'll try the saving the texture for a (RTT/ParticleSystem) if I can track down the problem the ParticleSytem.

[dark_sylinc]

I will rename ReadyForDisplay because I see the confusion it just caused.

Basically if you download an RTT when you get that message, you'll be downloading an empty texture, or something halfway.

That message should be renamed to ReadyForRendering and documentation more clear, since it's meant for regular textures informing they're done loading in a background thread, not that an RTT has finished rendering and is ready to be presented to the monitor.

Edit: Renamed and clarified. Thanks for the feedback.

[dermont]

I'm still having problems with particle systems and v2-2. Is there known issues?

This is the example code, similar code works on 2.1:

Running a number of times, stall occurs in different places. I have to Ctr+C at terminal, debug only shows details of the point at which I press Ctrl+C. Any advice on how to debug this.

[dark_sylinc]

Sounds like the known issue caused by lack of metadata cache.

Basically, what you're seeing is the particle FX getting a shader for a version with dummy texture, and then a new shader for the version with the loaded texture. The stall is caused by shader recompilation.

It happens at different places because the texture is loaded in background, so sometimes it gets loaded sooner, sometimes later; and when that finishes the new shader gets compiled. The metadata cache will prevent this recompilation nonsense.

[dark_sylinc]

Wait!
Are you talking about a small stutter stall, or a "full process freeze" that is unrecoverable (you have to kill the process)?

If the latter, and you're running on latest Mesa in Linux, it's possible you've run into this: https://bugs.freedesktop.org/show_bug.cgi?id=105339. Scratch that, you're using NVIDIA.


If it's a full process freeze, my next guess is that the background thread is throwing an exception, which is currently wreaking havoc in 2.2 (it will silently kill the background thread).

You may find more information by defining OGRE_FORCE_TEXTURE_STREAMING_ON_MAIN_THREAD in OgreMain/src/OgreTextureGpuManager.cpp to troubleshoot (see the doxygen's markdown manual section about 2.2).

Nvidia 390.25 (glvnd), tried with various driver versions.

The render window becomes unresponsive (freezes) and only part of the particle system is rendered. This can happen after running for a few frames or 500 hundred frames.
I have to press Ctrl+C from the terminal/ running gdb/apitrace or valgrind.

If it's a full process freeze, my next guess is that the background thread is throwing an exception, which is currently wreaking havoc in 2.2 (it will silently kill the background thread).

You may find more information by defining OGRE_FORCE_TEXTURE_STREAMING_ON_MAIN_THREAD in OgreMain/src/OgreTextureGpuManager.cpp to troubleshoot (see the doxygen's markdown manual section about 2.2).

Already tried defining OGRE_FORCE_TEXTURE_STREAMING_ON_MAIN_THREAD, didn't help much, gdb/backtrace reports different info each run.

[dark_sylinc]

Tried your code. I can see mUpdateRemainTime is a *very* large number, hence tuck in a near-infinite loop. I'm now looking into why is that happening.

[dark_sylinc]

Fixed. Thanks for the report.

I basically just fixed my own screw up.

[dermont]

Thanks, fix resolves the problem.
