Irrlicht Engine

I'm using only Class from Irrlicht sources like someone else,
I'm using this code only for introductory purposes/

Thank's to Irrlicht team.

I will not using Irrlicht any more, because I've created my own little DX10 engine with my own PhysX wrapper.....

Textures creation speeds up with mip maps.
I think this is the main reason.

But without mipmaps looks better.

You could enable and disable this option for needed objects

Just disable MIPMAPS

driver->setTextureCreationFlag(ETCF_CREATE_MIP_MAPS, false);

Just add this method by your own

Look:


virtual NxActor* getActor() = 0; //to IPhysxObject.h

inline NxActor* getActor() { return Actor; } //to CPhysxObject.h


It's very simple :wink:

Currently I made my own flexible PhysX wrapper for DirectX 10 with activetransforms and paging, with methods ...

Hello to ALL !!!!!!!!!!!

Here is my FluidEmitterSceneNode class/
Maybe it will be usefull for someone

I'm not sio2, I can share :lol:


#define MAX_PARTICLES 10000
class CFluidEmitterSceneNode : public scene::ISceneNode
{
private:

MyFluid *m_fluid;
NxFluidEmitter *m_emitter ...

Just use character controller capsule from NxCharacter.lib
This is the best way
but you also may take a look for "angular damping" settings

I've tried using it, but i dont know how to draw custom set of particles with custom coordinates

Do you mean global performance, or fluid performance ??

In global case we can just use active transforms, this will increase speed.
But with fluids I'm thinking for another way of drawing, because when we draw less than 10 000 particles everything is ok, but when we trying to draw more than 20000 ...

Congratulate me, boys !!!!!!!!!!!!!!!!!

Finally i made my PhysX fluid implementation, it was a simple task.
I made it using MyFluid class from SDK samples and CParticleSystemSceneNode from Irrlicht sources.

Here is the screen

Hi, guys !!!!!!!!!!!!!!!!!!

Could someone gime me an advice ??


This is dangling vertically revolute joints

NxRevoluteJoint* revJoint = NULL;
PhysXNode* box1 = physx->CreateBox(smgr->addCubeSceneNode(4), 4,4,4, vector3df(0,14,0));
box1->GetActor()->raiseBodyFlag(NX_BF_KINEMATIC ...

Cold someone please help me to prevent a strange artefacts

I found some optimization hints !!!!!!!!!!!!!!!!!!!!!!!!!!!!! :P :P

for triangle meshes

//hardware & non-hardware specific paging modes
if(hardware)
MeshShapeDesc.meshPagingMode = NX_MESH_PAGING_AUTO;
else
MeshShapeDesc.meshPagingMode = NX_MESH_PAGING_FALLBACK;


for scene

sceneDesc.flags ...

Comes from SDK docs -->

Only one application can use the PhysX hardware at a time. The first application to access the hardware obtains exclusive access to it; however, it is possible to prevent the SDK from using the hardware even if it is present (see Hardware Detection for details).

I've spent all night playng with physx feautures and found
a problem. :cry: :cry: :cry:


I have found a problem,
Its about number of physx objects.

When we create more than 1000 instances
framerate becomes critical ( about 30 fps, and less if 1000+ instances )

Is this PhysX limitations ...

You can generate terrain mesh in Milkshape3D
