Detailed Description

Abstract base class for texture nodes.

Constructor & Destructor Documentation

openvrml::texture_node::~texture_node

(

)

throw () [pure virtual]

Destroy.

Todo:

Proper resource deallocation in the viewer depends on the viewer not having been decoupled from the browser. We need to handle this better via some refcounting scheme.

openvrml::texture_node::texture_node	(	const node_type &	type,
		const boost::shared_ptr< openvrml::scope > &	scope
	)			throw () [protected]

Construct.

Parameters:

[in]	type	the node_type associated with the node.
[in]	scope	the scope the node belongs to.

openvrml::viewer::texture_object_t openvrml::texture_node::render_texture

(

viewer &

v

)

Insert a texture into a viewer.

Parameters:

[in,out]

v

viewer.

Returns:

object identifier for the inserted texture.

const openvrml::image & openvrml::texture_node::image

(

)

const throw () [pure virtual]

The image.

Returns:

the image.

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.

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.

openvrml::texture_node * openvrml::texture_node::to_texture

(

)

throw () [private, virtual]

Cast to a texture_node.

Returns:

a pointer to this texture_node.

Reimplemented from openvrml::node.

openvrml::viewer::texture_object_t openvrml::texture_node::do_render_texture

(

viewer &

v

)

[private, virtual]

render_texture implementation.

Parameters:

[in,out]

v

viewer.

Returns:

object identifier for the inserted texture.
