Irrlicht Engine

Hi,here is the IrrPhysX written by JP.It may be useful for you.

About rotate an actor,my code snippet as follows.

void setRotate(vector3df rot)
{
NxMat33 mat;
NxMat33 rotX, rotY, rotZ;
rotX.rotX ...

JP,thank you for your last help.now,I can attach PhysX to Irrlicht as well.I've create cloth and triangle object,and render them with Irrlicht..

But I am troubled by another problem.How to create a softbody that render with Irrlicht? I find there is nothing code about softbody in your IrrPhysX.

Hi,JP
Do you know how to construct a S3DVertex from NxMeshData??
I mean the NxMeshData stores vertex positions in verticesPosBegin,stores vertex normals in verticesNormalBegin,and stores vertex indices in indicesBegin,I want to use IVideoDriver::drawIndexedTriangleList() to draw a cloth.But,I only ...

Thanks JP.
The IrrPhysX is written by you,Don't you know when called CCloth::update().I think I must be wrong in here,so cann't draw debug data of the cloth,and the effect of render of the cloth is bad.

If you want to cut the cloth then yes you need to tear the necessary vertices.

If you're not calling CCloth update functions then how can you expect it to work correctly?

I'm not sure what your above post is saying about rendering and collision detection...
I'm sorry for my poor English. :cry ...

What amaze me is how you attach PhysX to Irrlicht.
I mean one hand is collision detecting of object and the other is render object with irrlicht.How do you achieve that?

Hi,JP.
I am reading your code conscientiously.I try to divide part function that's useful for me from your lib.
and I have some questions..

1. about render cloth
Now,I can render the cloth,but can't render the debug data.strangely,except cloth,I can render other NxActor debug data,such as cube ...

Thanks,,
I'll have a try.

Thanks JP..I've seen your code,It's not fit for me.you got the cloth stuff from mesh,I run the cloth example,when I set the triangle scale of cloth bigger than sphere,the sphere will fly through the cloth without collision.I want to control the number and scale of triangle of the cloth,I don't want ...

I am learning physx.I need create a cloth.I found it very hard to learn physx,here is the code of MyCloth written by OpenGL without any comment.I didn't learn OpenGL before.How to convert OpenGL code to Irrlicht.
/////// define some Nx argument //////
class MyCloth {
NxMeshData mReceiveBuffers ...

I want to control the particle system creating particle.
when I press 'A' it creat particles,press 'B' it don't create particles any more.

I created smoke effect in my scene.Now I need cancel the effect when I press a key.I don't know how to stop particle emitter creating particles.

turn() rotate node around its Y axis
pitch() around X
roll() around Z

to rotate node around its Z axis 45 degrees just call: roll(yourCilinderNode, 45.0f)

Here is my cylinder, it is a vertical.
It’s position is (x,y,z),I want rotate it,but it must ...

thanks arras for your code..But I still don't know how to count gimbal lock. For example,I have loaded the cylinder mesh successfully,I set cylinder position use cylinder->setPosition(-20,-20,0),then I roll(cylinder, -45) to make sure the cylinder cross the point(0,0,0).Now I want it can rotate ...
