Re: [osg-users] Store parent matrix inside of child

2015-01-05 Thread Robert Osfield

Hi Drake,

You could have a matrix wrapped up in your custom GizmoDrawable but you'd
have to be careful about when you passed on the matrix.

One normally doesn't cache matrices this way, as it usually isn't
required.  There is chance that you are trying to tackle a problem that
there is an established and better solution, but as don't say anything
about the actual problem you trying to solve, just focus on possible
solution to an unknown problem we can't provide any useful advice.

 Hi, all

 Below is my code:
 is it possible somehow store matrix transform of PAT inside of children

 Code:
 osg::ref_ptrosg::Switch sw = new osg::Switch;
 sw-setName(Switch);
 sw-addChild(scene,true);
 sw-addChild(getLineCube(pos,11),false);
 osg::ref_ptrAgentShape myPos = new AgentShape; // This is PAT
 myPos-setPosition(pos);
 myPos-addChild(sw);
 myPos-setName(AgentShape);
 osg::ref_ptrosg::Geode geodeGizmo = new osg::Geode;
 osg::ref_ptrGizmoDrawable gizmo = new GizmoDrawable;
 gizmo-setName(gizmo);
 gizmo-setGizmoMode( GizmoDrawable:: NO_GIZMO);
 gizmo-setTransform(matrixTrasform of PAT);
 geodeGizmo-addDrawable( gizmo.get() );
 geodeGizmo-setCullingActive( false );

 myPos-addChild(geodeGizmo);
 return myPos;



 Thank you!

 Cheers,

Re: [osg-users] Low frame rate ( Update Callback on 50 bones ).

2015-01-05 Thread Chris Hidden

Happy new years everyone! Hope everyone had a great holidays!

I just wanted to update this thread and bump it as I am now doing some further 
tweaking on getting things running optimally. 

I narrowed down some things, and I now have ONLY the hands being rendered in 
release mode.  I get around 45 fps.. which is ok, but I would like to see it 
higher.  Unless I am vastly overestimating the capability of this it should be 
able to render the hands up close to 60 fps on release mode.

I've tested running only the API without rendering the hands and the frame rate 
stays a solid 58-60 fps.  The moment I add the hands to the scene and they move 
around the FR drops to around 45.  So I know the sensor data is not the source 
of the delay.  

I tried a traversal class that runs through the hand model.  (Hand model is an 
FBX class with baked in texture and rigging exported from 3DS max) hoping to do 
all the work on the GPU:

 
Code:

class VBO_Updater : public osg::NodeVisitor
{

public:
VBO_Updater()
: NodeVisitor(NodeVisitor::TRAVERSE_ALL_CHILDREN)
{}
~VBO_Updater(){}
virtual void apply(osg::Node node)
{
traverse(node);
}

virtual void apply(osg::Geode geode)
{
unsigned int numGeoms = geode.getNumDrawables();

for (unsigned int i = 0; i  numGeoms; i++)
{
osg::ref_ptrosg::Geometry curGeom = 
geode.getDrawable(i)-asGeometry();

if (curGeom)
{
curGeom-setUseDisplayList(false);
curGeom-setUseVertexBufferObjects(true);
osg::ref_ptrVertexBufferObject df = 
curGeom-getOrCreateVertexBufferObject();
df-setUsage(GL_STREAM_DRAW);
osg::ref_ptrosg::StateSet stateset = 
curGeom-getOrCreateStateSet();
stateset-setAttributeAndModes(new 
osg::CullFace());
}
}

}

private:

};




But this didn't seem to do anything for the frame rate.  I assume that the fbx 
model is still not being skinned on the GPU.  How do I make sure that the GPU 
is doing the hard work and not the CPU?

Re: [osg-users] Low frame rate ( Update Callback on 50 bones ).

2015-01-05 Thread Christian Buchner

If I am not mistaken, you will have to run your own vertex shaders in order
to do hardware animation skinning. The osganimationhardware example
provides a very basic example of doing so.

This may mean that your shader might have to be hardcoded to work with a
specific 3D model (bone structure) only.

Well, Ill try describe what I'm trying to do. I have scene where I put object 
with this code: 

Code:
std::string path=models\\;

blendFunc-setSource(osg::BlendFunc::CONSTANT_ALPHA);
blendFunc-setDestination(osg::BlendFunc::ONE_MINUS_CONSTANT_ALPHA);
scene-getOrCreateStateSet()-setAttributeAndModes( new osg::BlendFunc 
);

osg::Material* material = new osg::Material;

pStateSet-setMode(GL_BLEND, true);

 I use my own class inherited from PAT, because I need my own values. This PAT 
contains gizmo from lib gizmo and osggizmo examples. When i put matrix 
transform of my osg::Node* scene, I can move object but it doesn't move PAT 
actually, so I trying understand how could I move whole PAT with this 
gizmo.[/code]

Re: [osg-users] Store parent matrix inside of child

2015-01-05 Thread Robert Osfield

Hi Drake,

I can't personally help you, I know nothing about gizmo.  You don't really
explain what you are trying to do either, you provide code, which is a
specific attempt at a solution to a problem, not a definition of the
problem which makes it doubly impossible to guess what you need to do.

I'd suggest when explaining stuff you don't provide code, but a high level
explanation of how you want to manage you scene and how gizmo affects this.

Robert.

Re: [osg-users] Store parent matrix inside of child

2015-01-05 Thread Trajce Nikolov NICK

Hi Drake,

just guessing by the subject of the email. If you want to store matrix to
some node (your child node) you can use the userdata of the node and
RefMatrix. Something like

osg::Matrix parentMatrix;
child-setUserData(new osg::RefMatrix(parentMatrix));

then dynamic_cast the userData to RefMatrix when you need it

Again, the hint is just by guessing. Robert is right, it is not clear what
you are after

Cheers,
Nick
