Метод	Описание
GetClosestGLInternalFormat ( PixelFormat format ) : int	Takes the Axiom pixel format and returns the type that must be provided to GL as internal format. If no match exists, returns the closest match.
GetClosestPixelFormat ( int format ) : PixelFormat	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. It is valid for this function to always return PixelFormat.A8R8G8B8.
GetGLInternalFormat ( PixelFormat format ) : int	Takes the Axiom pixel format and returns the type that must be provided to GL as internal format. GL_NONE if no match exists.
GetGLOriginDataType ( PixelFormat format ) : int	Takes the Axiom pixel format and returns type that must be provided to GL as data type for reading it into the GPU
GetGLOriginFormat ( PixelFormat format ) : int	Takes the Axiom pixel format and returns the appropriate GL one
GetMaxMipmaps ( int width, int height, int depth, PixelFormat format ) : int	Returns the maximum number of Mipmaps that can be generated until we reach the mininum format possible. This does not count the base level. In case that the format is non-compressed, this simply returns how many times we can divide this texture in 2 until we reach 1x1. For compressed formats, constraints apply on minimum size and alignment so this might differ.
OptionalPO2 ( int value ) : int	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.

GetMaxMipmaps() публичный статический Метод

Returns the maximum number of Mipmaps that can be generated until we reach the mininum format possible. This does not count the base level.

In case that the format is non-compressed, this simply returns how many times we can divide this texture in 2 until we reach 1x1. For compressed formats, constraints apply on minimum size and alignment so this might differ.

public static GetMaxMipmaps ( int width, int height, int depth, PixelFormat format ) : int
width	int	The width of the area
height	int	The height of the area
depth	int	The depth of the area
format	PixelFormat	The format of the area
Результат	int

OptionalPO2() публичный статический Метод

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.
