Member Function Documentation

void Textures::CreatePerlinTexture (  PerlinNoise *  perlin, GLuint  texture_id )  [static, private]

Creates a perlin texture of an arbitrary size. Parameters: perlin  Pointer to a perlin noise class, which describes the actual noise. texture_id  The OpenGL texture name which the created perlin noise shall be bound to. Definition at line 125 of file Textures.cpp.

void Textures::CreateTexture (  GLuint  tex_id, int  size_x, int  size_y, GLubyte *  raw_data )  [static, private]

Creates a mipmap texture. Parameters: tex_id  The OpenGL texture name to identify the texture. size_x  Horizontal size of the texture to be created. Does not have to be a value of the form: size_x = 2^i. size_y  Vertical size of the texture to be created. Does not have bo be a value of the form: size_y = 2^i. raw_data  Pointer to a sequence of conecutive values between 0 and 255. Since a RGB format is required, the sequence exactly has to be of the size: size_x * size_y * 3. Definition at line 138 of file Textures.cpp.

GLuint Textures::GetId (  int  texture_id  )  [static]

Returns the OpenGL identifier of a specific texture. Parameters: texture_id  The identifier of the texture which shall be retrieved (see defines). Returns: The OpenGL identifier for the texture specified by 'texture_id'. Definition at line 56 of file Textures.cpp.

void Textures::Load (   )  [static]

Loads all the textures and sends them to the memory of the graphics card. Definition at line 5 of file Textures.cpp.

bool Textures::LoadBMP (  char *  file_name, GLuint  texture_id )  [static, private]

Loads a windows bitmap file from disk (files with indexed colors not supported). Parameters: file_name  A character sequence describing the file to load. example: "/Images/Test.bmp". texture_id  The OpenGL texture name which the loaded bitmap shall be bound to. Returns: true if this routine succeeded; false if this routine failed. Definition at line 61 of file Textures.cpp.

void Textures::Release (   )  [static]

Releases all textures. Definition at line 51 of file Textures.cpp.
