Constructor & Destructor Documentation

TextureCubeGL()

TextureCubeGL

(

const TextureDescriptor &

descriptor

)

Parameters

descirptor

Specifies the texture description.

Member Function Documentation

updateSamplerDescriptor()

virtual void updateSamplerDescriptor ( const SamplerDescriptor &  sampler )

overridevirtual

Update sampler.

Parameters

sampler

Specifies the sampler descriptor.

Implements TextureBackend.

updateFaceData()

virtual void updateFaceData ( TextureCubeFace  side, void *  data  )

overridevirtual

Update texutre cube data in give slice side.

Parameters

side	Specifies which slice texture of cube to be update.
data	Specifies a pointer to the image data in memory.

Implements TextureCubemapBackend.

getBytes()

virtual void getBytes ( std::size_t  x, std::size_t  y, std::size_t  width, std::size_t  height, bool  flipImage, std::function< void(const unsigned char *, std::size_t, std::size_t)>  callback  )

overridevirtual

Read a block of pixels from the drawable texture.

Parameters

x,y	Specify the window coordinates of the first pixel that is read from the drawable texture. This location is the lower left corner of a rectangular block of pixels.
width,height	Specify the dimensions of the pixel rectangle. width and height of one correspond to a single pixel.
flipImage	Specifies if needs to flip the image.
callback

Implements TextureBackend.

updateTextureDescriptor()

virtual void updateTextureDescriptor ( const TextureDescriptor &  descriptor )

overridevirtual

Parameters

descriptor

Specifies texture and sampler descriptor.

Reimplemented from TextureBackend.

getHandler()

GLuint getHandler ( ) const

inline

Get texture object.

Returns

Texture object.

apply()

void apply

(

int

index

)

const

Set texture to pipeline.

Parameters

index

Specifies the texture image unit selector.
