## Public Members

- Radar ()
    Construct the abstract tracking object.

- long setRange (float Range, int ViewSize)
    Sets the world Range, and a pixel viewsize to scale positions by.

- long addItem (float x, float y, float z)
    Add an object to the radar.

- long clear ()
    Remove all objects.

- long status ()
    Returns a non-zero value if an error occured.

- long iterate ()
    Call this to reset the iteration through the objects Used in rendering implementation.

- long getNext (int& x, int& y, int& z)
    Retrieves the next object's position.

- virtual long render () = 0
    Implement this in subclasses to provide actual visible radar.

## Detailed Description

A generic 3D object tracking system.

Can be subclassed to use the information anyway needed.

## Member Function Documentation

### Radar::Radar()

Construct the abstract tracking object.

### long Radar::setRange(float Range, int ViewSize)

Sets the world Range, and a pixel viewsize to scale positions by.

Try playing with the range, and see what results you get. The ViewSize is the size (in pixels) of the actual representation. For example, if you plot the radar on a 200x200 area, use ViewSize=200

### long Radar::addItem(float x, float y, float z)

Add an object to the radar.

The coordinates are relative to the radar's position and orientation

### long Radar::clear()

Remove all objects.

Call before each frame.

### long Radar::status()

Returns a non-zero value if an error occured.

### long Radar::iterate()

Call this to reset the iteration through the objects Used in rendering implementation.

### long Radar::getNext(int& x, int& y, int& z)

Retrieves the next object's position.

Returns 0 if an object is available and a non-zero value if no more objects are available. Returns object's position on the grid in the reference variables.

### virtual long Radar::render() = 0`[pure virtual]`

Implement this in subclasses to provide actual visible radar.
