Detailed Description

A Renderer drawing particles as OpenGL lines.

The length of the lines is function of the Particle velocity and is defined in the universe space while the width is fixed and defines in the screen space (in pixels).

Below are the parameters of Particle that are used in this Renderer (others have no effects) :

Constructor & Destructor Documentation

GLLineRenderer ( float  length = 1.0f,
float  width = 1.0f 
)

Constructor of GLLineRenderer.

Parameters:
length : the length multiplier of this GLLineRenderer
width : the width of this GLLineRenderer in pixels

Member Function Documentation

virtual bool checkBuffers ( const Group group  )  [protected, virtual]

checks the buffers and prepare them

This method has to be implemented in derived class that uses buffers.
true must be returned if the buffers are found and initialized, false otherwise.

Parameters:
group : the group in which to check the buffers
Returns:
true if buffers are ready, false otherwise

Reimplemented from BufferHandler.

GLLineRenderer * create ( float  length = 1.0f,
float  width = 1.0f 
) [static]

Creates and registers a new GLLineRenderer.

Parameters:
length : the length multiplier of this GLLineRenderer
width : the width of this GLLineRenderer in pixels
Returns:
A new registered GLLineRenderer
Since:
1.04.00

virtual void createBuffers ( const Group group  )  [virtual]

Creates the buffers for this buffer handler in the given group.

If the buffers for this type of buffer handler already exists within the Group, they are priorly destroyed.
The type of buffers created depends on the state of the buffer handler at the time this method is called.

This method has to be overridden in derived classes that use buffers

Parameters:
group : the Group in which to create the buffers for this buffer handler

Reimplemented from BufferHandler.

virtual void destroyBuffers ( const Group group  )  [virtual]

Destroys the buffers for this buffer handler in the given group.

if the buffers dont exist, nothing happens.

This method has to be overridden in derived classes that use buffers

Parameters:
group : the Group in which to destroy the buffers for this buffer handler

Reimplemented from BufferHandler.

virtual void render ( const Group group  )  [virtual]

Renders a Group of particles.

Parameters:
group : the Group to render

Implements Renderer.
