Detailed Description

Manages a disk-based texture-image quadtree and supports loading individual texture images at different levels and locations in the tree.

Constructor & Destructor Documentation

TextureQTree()

tqt::TextureQTree::TextureQTree	(	std::string const &	filename,
		bool	flip,
		bool	sRGB
	)

constructor for a texture quad tree

Parameters

filename
flip	should the image be flipped to match OpenGL conventions
sRGB	are the textures in sRGB format?

~TextureQTree()

tqt::TextureQTree::~TextureQTree

Member Function Documentation

depth()

int tqt::TextureQTree::depth ( ) const

inline

the depth of the TQT

isTQTFile()

static bool tqt::TextureQTree::isTQTFile ( std::string const &  filename )

static

return true if the file looks like a TQT file of the right version

isValid()

bool tqt::TextureQTree::isValid ( ) const

inline

is this a valid TQT?

loadImage()

cs237::Image2D * tqt::TextureQTree::loadImage	(	int	level,
		int	row,
		int	col
	)

return the image tile at the specified quadtree node.

Parameters

[in]	level	the level of the node in the tree (root = 0)
[in]	row	the row of the node on its level (north == 0)
[in]	col	the column of the node on its level (west == 0)

Returns

a pointer to the image; nullptr is returned if there is an error. It is the caller's responsibility to manage the image's storage.

sRGB()

bool tqt::TextureQTree::sRGB ( ) const

inline

are the images sRGB?

tileSize()

int tqt::TextureQTree::tileSize ( ) const

inline

the size of a texture tile measured in pixels (tiles are always square)
