Detailed Description

Singleton class that manages texture unit allocation.

When a texture is binded, this singleton will search for the first free slot to allocate it. This removes the burden of managing texture units inside the program.

Member Function Documentation

void Tucano::TextureManager::bindTexture ( GLenum  texType, GLuint  texID, int  texture_unit  )

inline

Binds a texture to a unit given by the user.

int Tucano::TextureManager::bindTexture ( GLenum  texType, GLuint  texID  )

inline

Binds a texture to the first free texture unit and returns the allocated unit.

Returns

Allocated unit, or -1 if no free unit is available.

int Tucano::TextureManager::getAvailableUnit ( void  )

inline

Returns the first available texture unit.

static TextureManager& Tucano::TextureManager::Instance ( void  )

inlinestatic

Returns the unique instance. If no instace exists, it will create one (only once).

TextureManager& Tucano::TextureManager::operator= ( TextureManager const &  )

private

Assignment Operation.

void Tucano::TextureManager::setUnavailableUnit

(

int

unit

)

Sets one unit as unavaiable. in case something besides the texture manager has bound a texture to it.

void Tucano::TextureManager::unbindTexture ( GLenum  texType, int  texture_unit  )

inline

Unbinds the texture from the specific texture unit.

void Tucano::TextureManager::unbindTextureID ( GLenum  texType, GLuint  texID  )

inline

Unbinds a texture with given ID Searches texture unit vector for the texture and frees unit.

Parameters

texType	Texture type
texID	The ID handler to given texture
