Detailed Description

Represents a basic drawable object.

It's derived from GameObject and so has a position. A pure virtual function draw() is provided to use in drawing procedures. Also graphical objects have a radius which is supposed to be used in some tests, such as visibility and collision testing.

Constructor & Destructor Documentation

GraphicsObject::GraphicsObject

(

void

)

The constructor creates the object.

The position and radius are set to 0 by default.

Definition at line 14 of file GraphicsObject.cpp.

GraphicsObject::GraphicsObject

(

GLfloat

r

)

The constructor creates the object.

The position is set to zero by default.

Parameters

r	the objects radius

Definition at line 23 of file GraphicsObject.cpp.

GraphicsObject::GraphicsObject	(	Vector3	position,
		float	r
	)

Creates an graphical object.

Needed is the position and the radius. The radius is used for collision detection and the view frustum culling.

Parameters

position	the position of the object in 3-dimensional space
r	the radius of the object

Definition at line 35 of file GraphicsObject.cpp.

GraphicsObject::GraphicsObject	(	float	x,
		float	y,
		float	z,
		float	r
	)

Creates a graphical object.

Needed is the position and the radius. The radius is used for collision detection and the view frustum culling.

Parameters

x	the x-position of the object
y	the x-position of the object
z	the x-position of the object
r	the radius of the object

Definition at line 48 of file GraphicsObject.cpp.

GraphicsObject::~GraphicsObject

(

void

)

Destructor.

Definition at line 55 of file GraphicsObject.cpp.

Member Function Documentation

virtual void GraphicsObject::draw ( void  )

pure virtual

Implemented in ModelObject, SpaceShip, SpaceStation, Planet, and abstract.

float GraphicsObject::getCollisionRadius

(

void

)

Returns the radius of the object, usable for collision detection.

Definition at line 62 of file GraphicsObject.cpp.

float GraphicsObject::getRadius

(

void

)

Returns the radius of the object, usable for view frustum culling.

This function is basically the same as getCollisionRadius( void ). It is used, because some objects (as Planet) have two kinds of radius which allows to have collisions in another area than the actual object's size.
