Constructor & Destructor Documentation

VboManager::VboManager

(

)

[private]

The constructor.

Initializes the texture manager.

VboManager::VboManager

(

const VboManager &

source

)

[private]

The copy constructor.

Should not be called.

VboManager::~VboManager

(

)

[private]

The destructor.

Destroyes the texture manager and frees all memory occupied by textures. Should only be called for program termination.

Member Function Documentation

void VboManager::createStandardMesh

(

struct vboEntry *

entry

)

[private]

Creates a standard mesh if no file is available.

Creates the raw data for a square plane in the x/z-plane sized 100.0 world units centered at the origin.

Parameters:

entry

The entry in which to load the raw data

void VboManager::loadBmm

(

struct vboEntry *

entry

)

[private]

Loads raw data from a bmm file.

void VboManager::calculateNormals

(

struct vboEntry *

entry

)

[private]

Calculates the normals for each vertex in an entry.

Calculates the normals for each vertex based on the normals of each adjacent triangle.

void VboManager::createVbo

(

struct vboEntry *

entry

)

[private]

Creates VBOs from raw data.

void VboManager::loadObject

(

struct vboEntry *

entry

)

[private]

Loads a triangle mesh from file to OpenGL.

Loads bmm-Meshes. These meshes have a local coordinate system that is oriented as follows: x-Axis is the facing direction of the mesh, y-Axis is the top-direction of the mesh and z-Axis is right from the viewpoint of the mesh. Note that the normals saved witin the file will be replaced by freshly calculated ones.

Parameters:

meshFilename

The mesh to be loaded (must be a proper bmm, otherwise fatal runtime errors will occur).

void VboManager::reload

(

)

[private]

Restores VBO's on resizes.

VboManager * VboManager::getInstance

(

)

[static]

The singleton getter.

The only way to access the manager

void VboManager::registerObject

(

const string &

filename

)

Registers a texture for use in the Texture Manager.

Adds a texture if not already present, otherwise increases its count.

Parameters:

filename

Must be a valid filename otherwise a default image will be loaded.

void VboManager::unregisterObject

(

const string &

filename

)

Unregisters a texture.

Removes a texture from memory if no longer used by other objects, otherwise decreases its count.

Parameters:

filename

Must be a filename already registered otherwise the call will have no effect.

void VboManager::processEvent

(

SDL_Event &

event

)

[virtual]

A method to deal with SDL_Event.

Implements EventListener.

struct vboEntry * VboManager::getEntry

(

const string &

filename

)

[read]

string VboManager::toString

(

)

const [virtual]

Returns a textual representation.

Returns:

a string descriping the run-time object

Implements EventListener.

string VboManager::className

(

)

const [virtual]

Returns the class name of the object.

Returns:

a string with the name of the object's class

Implements EventListener.

enum classId VboManager::classId

(

)

const [virtual]

Returns the class id of the object.

Returns:

an id of the object's class

Implements EventListener.
