static std::string makVrv::DtGlTextureUtils::textureName ( unsigned int id )

static

get the name

static int makVrv::DtGlTextureUtils::textureSize ( unsigned int id )

static

texture size in bytes

static int makVrv::DtGlTextureUtils::width ( unsigned int id )

static

This is width of texture/highest-resolution mip map.

is it a compressed format? (e.g: GL_COMPRESSED_SRGB_ALPHA -> true)

static int makVrv::DtGlTextureUtils::sizeInBytesOfCompressedTextureWithMipMaps	(	int	internalFormat,
		int	startMipMapWidth,
		int	startMipMapHeight
	)

static

compute the size of compressed mip mapped texture with mip map 0 as [startMipMapWidth, startMipMapHeight]

static int makVrv::DtGlTextureUtils::sizeOfMipMap	(	int	internalFormat,
		int	width,
		int	height
	)

static

compute the size of compressed a single mip map [width, height]

static const char* makVrv::DtGlTextureUtils::formatToString ( int format )

static

convert a gl (texture) format to a string

static void makVrv::DtGlTextureUtils::computeCompressedSize	(	int	internalFormat,
		int	width,
		int	height,
		int	depth,
		int &	blockSize,
		int &	size
	)

static

compute the size and block size of a given compressed format for a resolution of width x height
