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.

Member Function Documentation

size_t openvrml::texture_node::components (   )  const throw () [pure virtual]

Get the number of components for the image. Returns: the number of components for the image. Implemented in openvrml::vrml97_node::image_texture_node, openvrml::vrml97_node::movie_texture_node, and openvrml::vrml97_node::pixel_texture_node.

size_t openvrml::texture_node::frames (   )  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. Implemented in openvrml::vrml97_node::image_texture_node, openvrml::vrml97_node::movie_texture_node, and openvrml::vrml97_node::pixel_texture_node.

size_t openvrml::texture_node::height (   )  const throw () [pure virtual]

Get height of the image in pixels. Returns: the height of the image in pixels. Implemented in openvrml::vrml97_node::image_texture_node, openvrml::vrml97_node::movie_texture_node, and openvrml::vrml97_node::pixel_texture_node.

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

Get the pixels. Returns: the pixels. Implemented in openvrml::vrml97_node::image_texture_node, openvrml::vrml97_node::movie_texture_node, and openvrml::vrml97_node::pixel_texture_node.

bool openvrml::texture_node::repeat_s (   )  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 openvrml::vrml97_node::abstract_texture_node.

bool openvrml::texture_node::repeat_t (   )  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 openvrml::vrml97_node::abstract_texture_node.

texture_node * openvrml::texture_node::to_texture (   )  throw () [virtual]

Cast to a texture_node. Returns: a pointer to this texture_node. Reimplemented from openvrml::node.

const texture_node * openvrml::texture_node::to_texture (   )  const throw () [virtual]

Cast to a texture_node. Returns: a pointer to this texture_node. Reimplemented from openvrml::node.

size_t openvrml::texture_node::width (   )  const throw () [pure virtual]

Get width of the image in pixels. Returns: the width of the image in pixels. Implemented in openvrml::vrml97_node::image_texture_node, openvrml::vrml97_node::movie_texture_node, and openvrml::vrml97_node::pixel_texture_node.
