[SOLVED] How to Get Vertices In PlugIn

[wxywxy.ji]

In sciprt )

 

PlugInNode( Node );

 

Node : ObjectTerrain , MeshObject , Any Type .....

 

In Plugin )

 

void PlugInNode(Unigine::Node *pNode)

{

... 1. How To Get Vertex List , Any Type

 

 

... 2. How To Pass Engine.

 

GetVerticeInNode( pNode );

}

 

In Engine )

 

Header

 

static UNIGINE_API bool GetVerticeInNode(Unigine::Node* pUnigineNode);

 

Source

 

bool IKynapse::GetVerticeInNode(Unigine::Node* pUnigineNode)

{

if( NULL == pUnigineNode )

return false;

::Node* pNode = NULL;

 

pNode = static_cast<::Node*>(pUnigineNode->getInterface());

 

if( pNode == NULL )

reutnr false; <-- Any Time In This Position.

 

if( Node::OBJECT_MESH_DYNAMIC == pNode->getType() )

{

return false;

}

 

return true;

}

Look at the source/samples/Api/Objects example.

 

void my_object_create(NodePtr node,float time) {

ObjectMeshDynamicPtr object = ObjectMeshDynamic::create(node);
if(object.get() == NULL) Log::fatal("my_object_create(): is not an ObjectMeshDynamic\n");

object->clearVertex();
object->clearIndices();

int num = 1024;
float inum = 1.0f / num;
float scale = cosf(time * 2.0f) * 6.0f;

object->addFan(num + 2);
object->addVertex(vec3(0.0f));
object->addTexCoord(vec4(0.0f));
for(int i = 0; i <= num; i++) {
	float angle = UNIGINE_PI * 2.0f * i * inum;
	float radius = 20.0f + sinf(angle * 6.0f - time) * scale;
	float x = sinf(angle);
	float y = cosf(angle);
	object->addVertex(vec3(y * radius,x * radius,(radius - 20.0f) * 0.5f));
	object->addTexCoord(vec4(x,y,0.0f,0.0f));
}

object->updateBounds();
object->updateNormals();
object->updateTangents();
object->flush();
}

i will integrate kynapse in PlugIn.

 

i need only get vertex list.

 

vetice In Object Terrain , Mesh , ...... Any Type.

 

i would make cast class like ObjectMeshDynamicPtr for need vertex list?

 

and

 

i want cast.

 

when NodePtr inserted to Ungine Engine.

 

ex ) pNode = static_cast<::Node*>(pUnigineNode->getInterface());

 

ObjectTerrain* p = ( ObjectTerrain* ) pNode;

.

equal type......

.

ObjectMesh* p = ( ObjectMesh * ) pNode;

 

get Vertex List

[frustum]

I will add access to the vertices of ObjectMesh via API. The whole world (with terrain) can be converted into the single mesh in the editor.

[wxywxy.ji]

i can't understand.

 

please some code.

[frustum]

This class will be available in the new SDK.

class ObjectMesh : public virtual Object {

	virtual int getNumVertex(int surface) const = 0;
	virtual vec3 getVertex(int num,int surface) const = 0;
	virtual vec3 getNormal(int num,int surface) const = 0;
	virtual vec4 getTangent(int num,int surface) const = 0;
	virtual vec4 getTexCoord(int num,int surface) const = 0;

	virtual int getNumIndices(int surface) const = 0;
	virtual int getIndex(int num,int surface) const = 0;
};

 

You can export selected nodes into the single ObjectMesh file in the Unigine Editor Nodes window.

And after that use new Unigine::ObjectMesh class to obtain the world geometry.

[wxywxy.ji]

you said me that i will make ObjectMesh Interface Like UnigineNode.cpp File?

 

like this?

 

class ObjectInterface : public NodeInterface, public virtual Object {

 

public:

 

ObjectInterface(::Object *object) : NodeInterface(object), object(object) { }

virtual ~ObjectInterface() { }

 

virtual int getNumSurfaces() const { return object->getNumSurfaces(); }

virtual int findSurface(const char *name) const { return object->findSurface(name); }

virtual const char *getSurfaceName(int surface) const { return object->getSurfaceName(surface); }

 

virtual void setMaterial(const char *name,int surface) const { object->setMaterial(name,surface); }

virtual const char *getMaterialName(int surface) const { return object->getMaterialName(surface); }

 

virtual void setProperty(const char *name,int surface) const { object->setProperty(name,surface); }

virtual const char *getPropertyName(int surface) const { return object->getPropertyName(surface); }

 

private:

 

::Object *object;

};

 

/*

*/

Object *Object::create_object(Node *n) {

::Node *node = GetNodeInterface(n);

if(node == NULL || node->isObject() == 0) return NULL;

return new ObjectInterface(static_cast< ::Object*>(node));

}

 

/*

*/

void Object::release(Object *object) {

delete object;

}

[frustum]

We will release new SDK tomorrow. Unigine::ObjectMesh class will be available with the new SDK.

[wxywxy.ji]

thank you for reply.

 

ask for this topic after i will download new Ungine Engine.

[wxywxy.ji]

can i get down when?

[binstream]

Uploading now, will be available in 4-5 hours.

[wxywxy.ji]

Unfortunately, because my ungine engine have customized.

 

i would adjust that UnigineNode.cpp , UnigineNode.h , UnigineObject.h , UnigineObjectMesh.h , UnigineObjectMeshDynamic.h , UnigineObjectMeshSkinned.h in ungine source?

 

than can i get vertice any type object?

 

other question.

 

The correct usage is that make extern class , not adjust Unigine Engine Source?

 

how to use unigine engine?

[wxywxy.ji]

i can get vertex list in OBJECT_MESH.

 

but i can't vertex list in OBJECT_TERRAIN.

 

switch( pUnigineNode->getType() )

{

case OBJECT_MESH:

{

Unigine::ObjectMeshPtr object = Unigine::ObjectMesh::create( pUnigineNode );

int SurfaceCount = object->getNumSurfaces();

int VertexNum = 0;

for( int i = 0 ; i < SurfaceCount ; i++ )

{

VertexNum = object->getNumVertex( i );

}

}

break;

case OBJECT_TERRAIN:

// How To Get?

break;

case OBJECT_WATER:

// How To Get?

break;

case WORLD_CLUTTER:

// How To Get?

break;

case OBJECT_MESH_DYNAMIC:

{

Unigine::ObjectMeshDynamicPtr object = Unigine::ObjectMeshDynamic::create( pUnigineNode );

int VertexNum = 0;

VertexNum = object->getNumVertex();

}

break;

}

[manguste]

If you want to access terrain vertices, ObjectTerrain need to be converted into a simple ObjectMesh:

1. Open the Nodes panel in the editor.
   
2. Select ObjectTerrain.
   
3. Click "Export selected nodes into a mesh file" button.
   

Add the created mesh into the world and access its vertices via ObjectMesh interface.

 

ObjectWater vertices cannot be accessed (and it cannot be converted into a mesh). WorldClutter does not have any vertices at all, it just scatters node references.

[wxywxy.ji]

conclusion , not automatic get vertex list.

 

PlugIn is Useless.

 

make code Like ObjectMesh or insert Unigine Engine. :(

 

alway adjust Unigine Engine Source <_<

[wxywxy.ji]

i Found Another Way.

 

This Way Right?

 

[ Ex ]

 

[ Code In PlugIn ]

 

GetVertice( pNode );

 

int VertexCount = GetVertexCount();

 

loop(VertexCount)

{

Unigine::vec3 vPos = PopVertex( i );

}

 

[ Code In Engine Extern - Function ]

 

static std::list<UNIGINE::vec3> m_VertexList;

 

Unigine::vec3 PopVertex()

{

return m_VertexList; <= delete front iterator after Return Unigine::Vec3;

}

 

GetVertice (Unigine::NodePrt pNode)

{

switch( pNode )

{

case AnyType:

{

int NodeID = pUnigineNode->getID();

::Node *pNode = Node::getNode( NodeID ); <== ID IS Unique?

 

if( NULL == pNode )

return false;

 

pAnyType = ( AnyType * ) pNode;

 

::vec3 vPos = pAnyType->GetVertex(....)

 

m_VertexCount.push_back( convertUnigneVec3( vpos ) );

 

}

break;

 

.........

}

 

}

[wxywxy.ji]

please check this way.

I am no expert in kynapse and not sure what you exactly what to achive, but maybe you should rethink your plug-in approach and instead try to integrate it directly into unigine source (if available). Unfortunately Unigine C++ API is very limited at the moment. I would guess that you will run into all kinds of additional data access problems (beyond simple vertices) when your integration gets more complex. Have a look into existing pathfinding module as a possible blueprint for your kynapse integration
