Member Function Documentation

updateSamplerDescriptor()

virtual void updateSamplerDescriptor ( const SamplerDescriptor & sampler )

pure virtual

Update sampler.

Parameters

sampler

Specifies the sampler descriptor.

Implemented in Texture2DGL, TextureCubeGL, TextureCubeMTL, and TextureMTL.

updateTextureDescriptor()

virtual void updateTextureDescriptor ( const TextureDescriptor & descriptor, int index = 0 )

virtual

Update texture description.

Parameters

descriptor

Specifies texture and sampler descriptor.

Reimplemented in Texture2DGL, TextureCubeGL, TextureCubeMTL, and TextureMTL.

getTextureFormat()

PixelFormat getTextureFormat ( ) const

inline

Get texture format.

Returns

Texture format.

getTextureUsage()

TextureUsage getTextureUsage ( ) const

inline

Get texture usage.

Symbolic constant can be READ, WRITE or RENDER_TARGET.

Returns

Texture usage.

getTextureType()

TextureType getTextureType ( ) const

inline

Symbolic constant value can be either TEXTURE_2D or TEXTURE_CUBE.

Returns

Texture type.

hasMipmaps()

bool hasMipmaps ( ) const

inline

Check if mipmap had generated before.

Returns

true if the mipmap has always generated before, otherwise false.
