Detailed Description

Connects to the EVaRT real-time MoCap data stream.

Example

class EVaRT_client : public boost::signals::trackable
{
public:
        void operator()(const MoCapFrame &mocap)
        {
                cout << "Frame of data with " << mocap.frame.size() << " labeled markers received!" << endl;
                for (pvector::const_iterator it=mocap.frame.begin(); it!=mocap.frame.end(); it++)
                        cout << "Marker " << it - mocap.frame.begin() << " is at position " << *it << endl;
        }
};

int main()
{
        EVaRT evart;
        EVaRT_client client;

        evart >>= client; // client will receive the data at every frame
        evart.Open("129.219.202.15");
        
        // we can also ask for a frame of information;
        MoCapFrame mocap;
        evart.GetRecentFrame(mocap);
        cout << "Got frame of data with " << mocap.frame.size() << " labeled markers!" << endl;
        for (pvector::iterator it=mocap.frame.begin(); it!=mocap.frame.end(); it++)
                        cout << "Marker " << it - mocap.frame.begin() << " is at position " << *it << endl;

        for (;;) {} // loop forever so the client keeps getting the data.
}

Member Function Documentation

virtual bool Open

(

const char *

file_name

)

[virtual]

Opens the file and prepares for frame reading.

Returns:

true if an error occurs

Implements MoCapFile.

virtual int GetRecentFrame

(

MoCapFrame &

frame

)

[virtual]

Returns the frame information for the most recently received/read frame.

Returns:

the frame number of the frame (negative if an error occured).

Implements MoCapFile.

virtual int GetIndex

(

string const &

lab

)

const [virtual]

returns the index of a marker label (case sensitive)

Returns:

-1 if the label is not found

Implements MoCapFile.

Descendant& operator>>=

(

T &

link

)

[inline, inherited]

Connects a sequence of components using signals.

This operator is identical to signal_link::operator>= (it connects the left component to the right component, and returns a reference to the left component), except it is evaluated right to left. This makes it semantics more suitable for connecting a chain of connections.

Descendant& operator>>=

(

slot_selector_t< T, Signature >

link

)

[inline, inherited]

Allows slot functions other than operator() to be used in a sequence of components.

See also:

slot_selector()

Descendant& operator>=

(

T &

link

)

[inline, inherited]

Allows branching in a component connection sequence.

This operator is identical to signal_link::operator>>=, (it connects the left component to the right component, and returns a reference to the left component) except it is evaluated left to right. This makes its semantics more suitable for branching connections.

Descendant& operator>=

(

const slot_selector_t< T, Signature > &

link

)

[inline, inherited]

Allows slot functions other than operator() to be used with branching.

See also:

slot_selector()
