createAtlasLayout()

static Vector< Page > CeresEngine::TextureAtlasUtility::createAtlasLayout ( Vector< Element > &  elements, UInt32  width, UInt32  height, UInt32  maxWidth, UInt32  maxHeight, bool  pow2 = false  )

static

Creates an optimal texture layout by packing texture elements in order to end up with as little empty space as possible.

Algorithm will split elements over multiple textures if they don't fit in a single texture.

Parameters

elements	Elements to process. They need to have their input structures filled in, and this method will fill output when it returns.
width	Initial width of the atlas texture.
height	Initial height of the atlas texture.
maxWidth	Maximum width the atlas texture is allowed to grow to, when elements don't fit.
maxHeight	Maximum height the atlas texture is allowed to grow to, when elements don't fit.
pow2	When true the resulting atlas size will always be a power of two.

Returns

One or more descriptors that determine the size of the final atlas textures. Texture elements will reference these pages with their output.page parameter.
