IrrNewt irrlicht\newton framework

[white tiger]

I wrote a open source irrlicht\newton framework. Its name is IrrNewt. it is OOP. It not only contains functions wrapped from newton but also functions wrote by me. It's a full framework to easily integrate physics in your project. Here is a short list of its most important features:

-body with primitive collision (ellipsoid ,box, cylinder, cone, capsule)

-optimized tree collision body (addOctTreeSceneNode)

-optimized tree collision body based on terrain (addTerrainSceneNode)

-simple vehicle

-character controller

-raycast functions for collision detection (getCollisionPoint, getCollisionPoints,getFirstCollisionPoint) all of these use newton

-materials (including materials user defined functions callbacks, for example call a user define function when two materials is colliding (but you can decide to don't write any callbacks) . It is possible also assign the same material to lots of different bodies

-automatic calculation of lots of thing (primitive dimensions, tensor of inertia, tire width and radius, body-scene node position offset if in your model file the model is not centered (for example has feet at 0,0,0)exc..)

-camera physics (automatic calculation of the target)

-doesn't need newton user defined callbacks

-tree body serialization\deserialization (save and load a tree body from\to a file)

-create a body by simply pass the scene node (and the mesh for tree bodies)

-can show newton body as a wireframe rappresentation

Hey,

thanks for the nice framework. I just playing around with it a bit. There are some things id like to mention:

C++ related:
1. use abstract interfaces
2. dont make this framework a lib (everyone should add the sources to her/his project and will be fine)
3. be more carefull in comparing signed and unsigned ints

Newton related:
1. add some functions to the World like World::close(), World::dropAllBodies()
2. dont use glut for timing since you are using Irrlicht anyway (it has already a timer ITimer)

If i find more things, i let you know.

Very much thanks for the framework.

Cheers, Friedrich

thanks for the nice framework

thanks

use abstract interfaces

abstract interfaces require that all member function are virtual and this is slower that non virtual functions. I think that abstract interfaces are useful when an interface require multiple implementations, but in IrrNewt there is one implementation for every interface

dont make this framework a lib (everyone should add the sources to her/his project and will be fine)

simply don't add "dll_exports.hpp" to your project and write "#define ARES_API" somewhere (i change its name in the next release to IRRNEWT_API)

add some functions to the World like World::close(), World::dropAllBodies()

this wil be in the next release

dont use glut for timing since you are using Irrlicht anyway (it has already a timer ITimer)

version 0.11 use already the ITimer interface to calculate time step (pass 1.0f/(last_time-current_time) to newton )

If i find more things, i let you know

Thanks This help to improve the wrapper

0.3 released

i'm doing the same thing now, where can i download the source? i think it will help a lot, and reduce many of hardcode work. is it open source anyway?
thanks

Take a look at the irrlicht post for irrnewt, in the lastest pages 17-18 there is a link where I re-upload this wrapper.
I think we can recompiled and better for the next newton version , what do you think?

Ok guy I deleted all of the post starting from my own, before the thread go out of hand.
It was my fault the thread got derailed, I should have known better.
Thank you for the support to everybody, but it is better to just focus in Netwon issues.

About IrrNewt, I did not read the hold thread over the Irrlith forum because it is too long, I just read the last few pages and I can only say that if White Tiger wants to get an eally start he can make a post in this thread or send me a PM.
