if you're not using MSVC then you need to recompile IrrPhysx.

If you're not using Irrlicht 1.4.2 then you need to recompile IrrPhysx.

I recommend recompiling no matter which compiler / Irrlicht version you use.

One Question: Is IrrPhysx able to do what NVIDIA shows in the NVIDIA PhysX Particle Fluid Demo?

I've played with that nvidia fluid demo quite a bit. I believe IrrPhysx should be capable of calculating the physics seen in that demo, assuming the demo is running on an nvidia card that exposes PhysX hw acceleration.

Rendering the results could be an issue. I've mentioned instancing earlier in this thread and this is what would be needed for efficient rendering - you would not want, say, 5000 Irrlicht scene nodes for each of 5000 "water particles".

Some form of metaball shader is probably used in the demo too. If anyone knows exactly the technique used I'd be most interested.

I'd planned on looking at IrrPhysx over the holidays so maybe I'll get chance to put together my own water physics demo. 8)

Note that you can use any physics engine run in sw to do a physics water demo. The difference with the nvidia demo is that it's designed for hw acceleration on specific nvidia cards so that they can get the (relatively) large amount of water particles - it's the number of water particles that makes the nvidia demo look so good...

Because of that I ask, I HAVE an GF8800 and I like the Fluid Demo very much.

Thx for the answer btw.

Are you going to make a fluid demo?

The windows version of gcc and PhysX do not get along. You'll need to use msvc to compile an application using the later PhysX versions in order to get it to work.

Currently there's no support for particle effects in IrrPhysx but it's something that will hopefully get added later.

sio2, if you manage to do anything with it then it would be cool if I could put it into IrrPhysx properly!

It sure would be cool.

The nvidia demo has up to 60000 (and more!) water particles. One scene node per-particle would kill the cpu so we'd need something like a PhysX managed CWaterVolumeSceneNode. There would also need some serious shader work to render that lot. The nvidia demo also has reflection and refraction - simple enough to do, but yet more render passes (my 8800 seems to handle it quite well, though).

Microsoft screwed up.. The msvc is not compiling anything! Can someone just compile one? (I want to use physics with gcc)

that would be interesting, having a general sort of manager-object to handle multiple PhysX fluid particles. It'd be cool to see you produce a fluid demo!

compile what? irrPhysX libs to use with gcc?

all you guys using devcpp, can I ask why you hesitate to just switch to MSVC? if not planning on porting outside windows OS, you should really consider switching to MSVC



(a little offtopic)

Has anyone tried using PhysX on an 64bit XP?

Although nVidia claims PhysX applications (including the system software) is compatible with XP64, the SDK only contains sample binaries and libs for 32bit windows so it doesn't seem as though 64bit is supported for development.

Any ideas? Is it even possible to develop PhysX applications on XP64?

Hi guys! First post after lurking and using Irrlicht for about a week (loving it so far).

I'm really just messing around with Irrlicht atm (made Pong ftw), and decided to try it out with a physics engine. Basically I'll use whichever engine has the greatest ease of use and most documentation, and following the great JP through various threads, PhysX was it. irrPhysx of course made that decision a lot easier, which brings me to the point of this paragraph - many, many thanks to JP for all his effort making this wrapper for people exactly like me.

That said, I can't get it to work :P I've added the irrPhysx include and lib folders in VC++'s directories, and basically just copied the Boxes example code to a new project and hit 'compile'. Obviously there's something I've failed to link, but I can't find anywhere that says "to use this in your projects, and X and Y to directories". If someone could point them out, I'd appreciate it.

Had similar problems getting Irrlicht to work (new to all C++'s compiling and linking, but I learn by experimentation), but that was evidently a lot simpler :( Apparently these things are too obvious to go in readme's or something.

Using MSVC++ 2008 Express (for now), and Irrlicht 1.4.2 on Vista x64. Cheers!

EDIT: Oh, almost forgot! The build log, if it helps (though presumably you all know the answer already):

Oh! And for the record, the game example crashes before it loads - someone else mentioned the same problem earlier in this thread. Loads up all the meshes and textures then just hits a wall, although I don't think that's at all related.

seems like you forgot to include the "common code" files too, which have to be included/added to your project to get the samples to compile.

IMO, maybe there should be a bog-standard "hello-world" sample, something that just shows how to use irrphysx in the simplest possible way.
I'll give it a shot later today (on my main PC, can't use physx on my XP64 laptop :()

i've had similar problems before too. The solution was already posted before somewhere, but your problem might be different.
are you sure your physx scene is even being created (not returning a null in initilisation)?
Also make sure you're using the right system-software and SDK versions (and dll) combinations.

Cheers for the response. You always get a bunch of noob questions on these forums for complex things, and I'm loathe to sound like one of them :P

Sorry, that last post was a bit rushed because I had to run off to work. I included the ones I said first, and it didn't work. Then I included CommonCode directory because some of the header names looked familiar from the errors (e.g. ShapeCreation) (that goes under "Include files", right?), but it still didn't work. Then I thought I'd add a few important-sounding include and lib folders from the PhysX SDK folder, but that didn't fix it either.

Just now I noticed a previous post I missed, saying I have to add those CommonCode files to my project, rather than just include them. I don't know why and haven't read that anywhere else but here as the result of an error, so a big +1 for bog-standards. So anyway I added them in, and it cut down the unresolved external symbols - now I'm down to:

Code: Select all

1>Tango.obj : error LNK2019: unresolved external symbol "void __cdecl IrrPhysx::removePhysxManager(class IrrPhysx::IPhysxManager *)" (?removePhysxManager@IrrPhysx@@YAXPAVIPhysxManager@1@@Z) referenced in function _main

1>Tango.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) class irr::IrrlichtDevice * __cdecl irr::createDevice(enum irr::video::E_DRIVER_TYPE,class irr::core::dimension2d<int> const &,unsigned int,bool,bool,bool,class irr::IEventReceiver *,char const *)" (__imp_?createDevice@irr@@YAPAVIrrlichtDevice@1@W4E_DRIVER_TYPE@video@1@ABV?$dimension2d@H@core@1@I_N22PAVIEventReceiver@1@PBD@Z) referenced in function _main
The first two of those errors mention PhysxManager, so I tried actually adding CPhysxManager .h and .cpp to the project as well which seemed to help except for saying it couldn't find NxPhysics.h, so I added the Physx Physics SDK to the includes, which gave me more missing files, so I added all those to the includes too, and ended up with about 24 unresolved external symbols :( The third one seems to be about the IrrlichtDevice, which should work fine... Odd.

As for the game, it's that exact same scenario as on page 4. I'd love to help with whatever debugging I could do, but until iPx (I like that as an abbreviation ;)) itself compiles, that's not going to yield many results.

Thanks again.

EDIT: Oh and I forgot again (man!) - I'm using the links in the first post of this thread - irrPhysx 0.2, PhysX SDK 2.8.1 and that System Software that ISN'T the most recent.
