Static Public Member Functions | |
static GLenum | getGLOriginFormat (PixelFormat mFormat) |
Takes the OGRE pixel format and returns the appropriate GL one. | |
static GLenum | getGLOriginDataType (PixelFormat mFormat) |
Takes the OGRE pixel format and returns type that must be provided to GL as data type for reading it into the GPU. | |
static GLenum | getGLInternalFormat (PixelFormat mFormat, bool hwGamma=false) |
Takes the OGRE pixel format and returns the type that must be provided to GL as internal format. | |
static GLenum | getClosestGLInternalFormat (PixelFormat mFormat, bool hwGamma=false) |
Takes the OGRE pixel format and returns the type that must be provided to GL as internal format. | |
static PixelFormat | getClosestOGREFormat (GLenum fmt) |
Function to get the closest matching OGRE format to an internal GL format. | |
static size_t | getMaxMipmaps (size_t width, size_t height, size_t depth, PixelFormat format) |
Returns the maximum number of Mipmaps that can be generated until we reach the mininum format possible. | |
static size_t | optionalPO2 (size_t value) |
Returns next power-of-two size if required by render system, in case RSC_NON_POWER_OF_2_TEXTURES is supported it returns value as-is. |

static GLenum Ogre::GLPixelUtil::getClosestGLInternalFormat | ( | PixelFormat | mFormat, |
bool | hwGamma = false |
||
) | [static] |
Takes the OGRE pixel format and returns the type that must be provided to GL as internal format.
If no match exists, returns the closest match.
mFormat | The pixel format |
hwGamma | Whether a hardware gamma-corrected version is requested |
static PixelFormat Ogre::GLPixelUtil::getClosestOGREFormat | ( | GLenum | fmt | ) | [static] |
Function to get the closest matching OGRE format to an internal GL format.
To be precise, the format will be chosen that is most efficient to transfer to the card without losing precision.
static GLenum Ogre::GLPixelUtil::getGLInternalFormat | ( | PixelFormat | mFormat, |
bool | hwGamma = false |
||
) | [static] |
Takes the OGRE pixel format and returns the type that must be provided to GL as internal format.
GL_NONE if no match exists.
mFormat | The pixel format |
hwGamma | Whether a hardware gamma-corrected version is requested |
static GLenum Ogre::GLPixelUtil::getGLOriginDataType | ( | PixelFormat | mFormat | ) | [static] |
Takes the OGRE pixel format and returns type that must be provided to GL as data type for reading it into the GPU.
static GLenum Ogre::GLPixelUtil::getGLOriginFormat | ( | PixelFormat | mFormat | ) | [static] |
Takes the OGRE pixel format and returns the appropriate GL one.
static size_t Ogre::GLPixelUtil::getMaxMipmaps | ( | size_t | width, |
size_t | height, | ||
size_t | depth, | ||
PixelFormat | format | ||
) | [static] |
Returns the maximum number of Mipmaps that can be generated until we reach the mininum format possible.
This does not count the base level.
width | The width of the area |
height | The height of the area |
depth | The depth of the area |
format | The format of the area |
static size_t Ogre::GLPixelUtil::optionalPO2 | ( | size_t | value | ) | [static] |
Returns next power-of-two size if required by render system, in case RSC_NON_POWER_OF_2_TEXTURES is supported it returns value as-is.
