IPhysics - Newton/Irrlicht framework

[RapchikProgrammer]

// start iphysics
CPhysics physics;
physics.init(PhysX);

Well ya this is exactly how i was thinking of doing this, but now when i come to think of it it needs someone who is really good with both the physics engines to make this kind of library! I thought i could just make one for newton then someone else can add a physx version, but to make this library work it needs to have its own base, which will calculate data in its format before passing it on! Its a lot of work, but if someone knows both the engines he shud do it!

Hope that helps someone.

HI

I am getting the following compile error:

fatal error LNK1262: link failed due to mismatched versions of 'C:\Program Files\MSV.NET2003\Vc7\bin\c2.dll' and LINK.EXE

I saw this question asked a couple of times by others, but never saw an answer.

I'm using visual studio 2003 & Irrlicht 1.1
I have used project files that work for all my other irrlicht examples, and setup the include and library paths for IPhysics and Newton (I think )

Any ideas guys ?

[TheRLG]

// start iphysics
CPhysics physics;
physics.init(PhysX);

Something more like

Code: Select all

IPhysicsDevice* pDevice = createPhysicsDevice(EPDT_PHYSX);

[monkeycracks]

Any estimation on when character control will be done? I'm really looking forward to it.

[RapchikProgrammer]

I have always had a problem with character controller, so its becoming really difficult for me to implement it! As soon as its done ill upload it! Currently, i have added materials and joints, but joints are not working properly for some reason! Neways, ill try to do it as soon as i can! I hope nick_japan can do it before me!

yeah! you read my recent post here?
http://irrlicht.sourceforge.net/phpBB2/ ... &start=105

we really need someone to create such a library!

[TheRLG]

yeah! you read my recent post here?

Actually, I hadn't, but great Irrlicht-using-minds think alike, apparently.

I've been working on an implementation of PhysX for IPhysics since my last post here on this thread.

I've started by looking at dmitrii's jf2 implementation as a reference/ something to start from. Well, after looking at jf2 code, it's like a bowl of spaghetti with meat balls in it. There are so many inconsistencies and unneccessary code sprinkled all over the place. I'm surprised that it even works.

Jf2's documentation is nil. Not all is bad though, it's the only implementation of PhysX for Irrlicht so I can't knock dmitrii for his efforts so far with jf2. And in time, jf2 may mature into a formidable solution for irrlicht users who want to incorporate PhysX into their project.

Next, I took a look at Ogre3D's physX implementation, NxOgre. It's like night and day compared to jf2. The code and design of NxOgre are well thought out and implemented. It has a professional sheen to it much like irrlicht's code.

So, it's going to take some time to study the three implementation and put together an implementation that is as structurely elegant as NxOgre but with the simplicity of IPhysics.

Clicking on LNK1262 in the Output window and pressing F1, the help file then gives some information on this error. It says:

Your computer has a mismatched compiler/linker. For example, LINK.EXE and C2.DLL communicate via an interface, and if the interface versions don't match, the linker emits this error.

To me, this says "all bets are off". Without more information I'd suggest a reinstall of Visual Studio.

Also, it may be an idea to get the latest version of Irrlicht: 1.2.

Well visual studio betrayed me! I had included hinge joints and was trying to do character controller when during saving vs gave an error and shut down and when i opened the workspace again, CPhysics.cpp was empty!!! I had an old backup wid nothing! So rit now i have no idea wat i am gonna do tho, so here is that old backup neated out a bit! IPhysics now supports debugging and materials!

Hi there

I'm really loving IPhysics, and I've been able to get it working quite nicely.
However, I have a little problem...

I have the CRT memory leak detector routine running on my applcation, and even after delete'ing and close()'ing (in reverse order of course) IPhysics, I receive literally hundreds of notifications of memory leaks - all supposedly allocated but uninitialized memory on the heap.

I can turn off IPhysics, and they disappear, so it definitely thinks the leak is in IPhysics somewhere.

Here's a little taster of the report: (Even with new redefined with __LINE__ and __FILE__, it refused to give any more info, so source of the leak is hard to define):

Code: Select all

Detected memory leaks!

Is this likely to be a genuine leak, or is the CRT just freaking out because Newton uses malloc and free?

I'm not accusing your code of leaking, I just wanted to check whether this is a known problem, or whether the CRT is smoking something

Thanks

(sorry about the long code snippet)

iPhysics looks like a great wrapper around newton, had a quick play with it and got it into a custom project with spheres, cubes and the test car thingy driving around in one scene (on a lightmapped my3d mesh) all working very nicely.

however 2 things I need to know before using it further:

1. Is it currently only supporting abitrary meshes that are static (ie the "levels" or what have you meshes). If I need a dynamic object that moves around the world, hitting other things and it is NOT a test sphere, test Cube or car how would I get it in using iphysics interface?? (Would I need to edit the sourcecode of i-physics and set it up there).

I just want a mesh that isn't a testnode to be moving around and reacting dynamically (as the spheres and cubes do currently). I have no problem with "static" meshes that don't react to anything but are collided with ok.

2. I've been using it with the supplied irrlicht dll and compiling against 1.2 irrlicht code. If I go back to my very customised irrlicht code (mostly based on 0.12!!!) will i-physics work ok with this or does it depend on fixes/advances in later irrlicht revisions.

Rgds and thanks for hard work!

To clarify, I can load any mesh and surround it with a cube/sphere bounding (collision box) by adding sphere/cube but there is no cylinder type? or anyway to use cusom collision geomtry (simplified around a complicated mesh)?

Edit > ok iv'e looked at the source (rather than the docs) and found that it was simple enough to add in the missing "cylinder" functionality and include the files in my test project so now I have A SPhysicsCylinder with radius and height.
