TextureCubeMap(const TextureCubeMap& cm, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_StateAttribute(osg, TextureCubeMap, TEXTURE)

virtual int compare(const StateAttribute& rhs) const

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs

void setImage(const Face, Image* image)

Set the texture image for specified face.

Image* getImage(const Face)

Get the texture image for specified face.

const Image* getImage(const Face) const

Get the const texture image for specified face.

inline void setTextureSize(const int width, const int height) const

Set the texture width and height.

inline void getTextureSize(int& width, int& height) const

Get the texture subload width.

void setSubloadCallback(SubloadCallback* cb)

SubloadCallback* getSubloadCallback()

const SubloadCallback* getSubloadCallback() const

void setNumMipmapLevels(unsigned int num) const

Set the number of mip map levels the the texture has been created with, should only be called within an osg::Texuture::apply() and custom OpenGL texture load

unsigned int getNumMipmapLevels() const

virtual void apply(State& state) const

On first apply (unless already compiled), create the minmapped texture and bind it, subsequent apply will simple bind to texture
