Detailed Description

Abstract base class for texture nodes.

Todo:

Clean this up. It would be better just to have an accessor for an SFImage along with the repeatS and repeatT accessors.

Constructor & Destructor Documentation

~TextureNode (    )  throw () [pure virtual]

Destructor.

TextureNode (  const NodeType &    nodeType, const ScopePtr &    scope )  [protected]

Constructor. Parameters: nodeType  the NodeType associated with the node. scope  the Scope the node belongs to.

Member Function Documentation

const SFBool & getRepeatS (    )  const throw () [pure virtual]

Get the flag indicating whether the texture should repeat in the S direction. Returns: TRUE if the image should repeat in the S direction, FALSE otherwise. Implemented in AbstractTexture.

const SFBool & getRepeatT (    )  const throw () [pure virtual]

Get the flag indicating whether the texture should repeat in the T direction. Returns: TRUE if the image should repeat in the T direction, FALSE otherwise. Implemented in AbstractTexture.

size_t height (    )  const throw () [pure virtual]

Get height of the image in pixels. Returns: the height of the image in pixels.

size_t nComponents (    )  const throw () [pure virtual]

Get the number of components for the image. Returns: the number of components for the image.

size_t nFrames (    )  const throw () [pure virtual]

Get the number of frames for a time-dependent texture. Returns: the number of frames. Todo: This needs to go away. Time-dependent textures might not be frame-based. For instance, consider an SVG animation.

const unsigned char * pixels (    )  const throw () [pure virtual]

Get the pixels. Returns: the pixels.

TextureNode * toTexture (    )  throw () [virtual]

Cast to a TextureNode. Returns: a pointer to this TextureNode. Reimplemented from Node.

const TextureNode * toTexture (    )  const throw () [virtual]

Cast to a TextureNode. Returns: a pointer to this TextureNode. Reimplemented from Node.

size_t width (    )  const throw () [pure virtual]

Get width of the image in pixels. Returns: the width of the image in pixels.
