WPCG::WP_TextureManager Class Reference
#include <WP_TextureManager.h>
List of all members.
Detailed Description
this singleton class is used for managing and storing all textures in such a way that only necessary textures are resident and textures are shared between models (objects). It makes use internally of WP_Texture objects. These texture objects are able to generate a texture from the following image formats:
(.bmp), Cut (.cut), Doom flats and textures, Icon (.ico), Jpeg (.jpg, .jpe, .jpeg), Lbm (.lbm), Pcd (.pcd), ZSoft Pcx (.pcx), Pic (.pic), Portable Anymap (.pbm, .pgm, .ppm), Portable Network Graphics (.png), Sgi (.sgi, .bw, .rgb, .rgba), Truevision Targa (.tga) and Tiff (.tif, .tiff) images

Member Function Documentation
WP_TextureManager * WPCG::WP_TextureManager::getInstance |
( |
|
) |
[static] |
|
|
this function is used to obtain a pointer to the only instance of this class (singleton) -
Returns:
-
a pointer to the only instance of this class
|
int WPCG::WP_TextureManager::getTexture |
( |
const string & |
name, |
|
|
void * |
owner |
|
) |
|
|
|
this function returns the texture ID (an OpenGL texture ID) belonging to the queried texture. If the texture is currently not maintained by the texture manager, the manager will load it. -
Parameters:
-
name |
the name of the texture, for example texture1.bmp or roof.pcs. For now only the 24 bit .bmp and 24 bit compressed/uncompressed .pcx format are supported
|
owner |
a void pointer to the owner of the texture (e.g. an object). This is used to internally keep track of how many objects use a particular texture |
-
Returns:
-
a texture ID with can be directly used in OpenGL's glBindTexture call, 0 in case of failure
|
bool WPCG::WP_TextureManager::removeTextures |
( |
void * |
owner |
) |
|
|
|
this function removes all textures belonging to this object. In fact it only removes this object from the textures' internal owner list. Only if this list is empty, the texture is removed from the texture manager. It should be called when an object is destroyed -
Parameters:
-
owner |
a void pointer to an object of which all textures are removed |
-
Returns:
-
a boolean indicating the success or failure of this function
|
Member Data Documentation
bool WPCG::WP_TextureManager::mipmapping
|
|
|
this boolean indicates if mipmapping should be used for textures |
