PowerUI.AtlasStacks Class Reference

Detailed Description

All the major stacks used by PowerUI. Each one represents a stack of texture atlases which are shared across all UI's.

Static Public Member Functions
static void	SetRate (int rate)
	Called when the global UI rate changes. More...
static void	Start ()
	Creates our stacks. More...
static void	Update ()
	Called at the global rate to e.g. optimise the atlases or trigger threaded draws. More...
static void	Optimise ()
	Attempts to optimise the major atlases. Only does anything if they need it. More...
static void	Clear ()
	Clears all stacks. More...
static void	Flush ()
	Flushes all atlases that require it. More...

Static Public Attributes
static int	InitialSize =1024
	The minimum starting atlas size. More...
static AtlasStack	Text
	The atlas stack used for rendering SDF text. All fonts share the same atlases. More...
static AtlasStack	Graphics
	A stack of temporarily buffered atlases. More...

Properties
static int	TextSpacing [get, set]
	The spacing around letters on the text atlas. More...
static int	GraphicsSpacing [get, set]
	The spacing around images on the graphics atlas. More...
static int	MaxSize [get]
	The maximum possible size that atlases can be on this hardware. More...
static int	AtlasSize [get, set]
	The size of atlases to use. Auto clipped by MaxSize. More...

Private Attributes
const int	OptimiseFrequency =20
	The max frequency of optimise calls, in seconds. More...

Static Private Attributes
static int	RawTextSpacing =2
	The spacing around letters on the text atlas. More...
static int	RawGraphicsSpacing =0
	The spacing around images on the graphics atlas. More...
static int	OptimiseCount
	A counter which tracks optimise calls and throttles them to at most once every 30s. More...
static int	OptimiseFrameCount =OptimiseFrequency*UI.DefaultRate
	The max frame count until an optimise happens. More...
static int	RawMaxSize =2048
	The max available atlas size. See MaxSize. More...
