Detailed Description

Texture node for images.

Constructor & Destructor Documentation

Texture2D

(

const Tag &

tag

)

Creates a new 2D texture from an XML tag.

Parameters:

tag

XML tag with "size" attributes.

Member Function Documentation

void associate

(

)

[virtual]

Generates or loads the texture.

Is done here rather than finalize() because other nodes might need to get the texture's handle.

Exceptions:

NodeException

from load()

Reimplemented from Texture.

Texture2D * find	(	Node *	node,
		const string &	name
	)			[static]

Finds a Texture2D with a specific name.

Parameters:

	node	Node to start looking.
	name	Name of the node as specified by the user.

void generate

(

)

[protected, virtual]

Generates a blank texture.

GLint getRawFootprint

(

)

const [virtual]

How much memory the texture uses if uncompressed.

Implements Texture.

int getSize

(

)

const [inline, virtual]

Returns:

width of the texture.

void initLibraries

(

)

[static, protected]

Initializes required libraries, currently just DevIL.

Checks that DevIL libraries being run by the user are not older than the libraries used to compile Gander. If they are, warnings are issued. Either way DevIL is initialized by calling 'ilInit'.

Exceptions:

Exception

if DevIL version is incorrect.

void load

(

)

[protected, virtual]

Loads an image into the texture.

Exceptions:

	NodeException	if the libraries could not be loaded
	NodeException	if the image cannot be loaded
	NodeException	if the image cannot be bound as a texture

string toString

(

)

const [virtual]

Forms a string from the object's attributes.

Reimplemented from Texture.
