Texture3D()

Texture3D(const Texture3D& text, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_StateAttribute(osg, Texture3D, TEXTURE)

virtual int compare(const StateAttribute& rhs) const

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

virtual void getAssociatedModes(std::vector<GLMode>& modes) const

void setImage(Image* image)

Set the texture image.

Image* getImage()

Get the texture image.

inline const Image* getImage() const

Get the const texture image.

inline unsigned int& getModifiedTag(unsigned int contextID) const

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

Set the texture width and height. If width or height are zero then the repsective size value is calculated from the source image sizes.

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

Get the number of mip map levels the the texture has been created with

void copyTexSubImage3D(State& state, int xoffset, int yoffset, int zoffset, int x, int y, int width, int height)

Copy a two-dimensional texture subimage. As per glCopyTexSubImage2D. Updates portion of an existing OpenGL texture object from the current OpenGL background framebuffer contents at pos \a x, \a y with width \a width and height \a height.

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

static Extensions* getExtensions(unsigned int contextID, bool createIfNotInitalized)

Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created then and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object only be created with the graphics context associated with ContextID..

static void setExtensions(unsigned int contextID, Extensions* extensions)

setExtensions allows users to override the extensions across graphics contexts. typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
