Classes
class	DecodingContext
	This class is used to decode and decompress triangle data packed by the EncodingContext. More...

class	EncodingContext
	This class is used to encode and compress triangle data into a byte buffer. More...

struct	TriangleBlock
	A block of 4 triangles. More...

struct	TriangleBlockHeader
	A triangle header, will be followed by one or more TriangleBlocks. More...

class	TriangleHeader

struct	VertexData
	A single packed vertex. More...

Public Types
enum	EComponentData : uint32 { COMPONENT_BITS = 21 , COMPONENT_MASK = (1 << COMPONENT_BITS) - 1 }
	Amount of bits per component. More...

enum	EVertexXY : uint32 { COMPONENT_X = 0 , COMPONENT_Y1 = COMPONENT_BITS , COMPONENT_Y1_BITS = 32 - COMPONENT_BITS }
	Packed X and Y coordinate. More...

enum	EVertexZY : uint32 { COMPONENT_Z = 0 , COMPONENT_Y2 = COMPONENT_BITS , COMPONENT_Y2_BITS = 31 - COMPONENT_BITS }
	Packed Z and Y coordinate. More...

Static Public Attributes
static constexpr int	TriangleHeaderSize = sizeof(TriangleHeader)
	Size of the header (an empty struct is always > 0 bytes so this needs a separate variable) More...

static constexpr bool	ChangesOffsetOnPack = false
	If this codec could return a different offset than the current buffer size when calling Pack() More...

Detailed Description

Store vertices in 64 bits and indices in 8 bits + 8 bit of flags per triangle like this:

TriangleBlockHeader, TriangleBlock (4 triangles and their flags in 16 bytes), TriangleBlock...

Vertices are stored:

VertexData (1 vertex in 64 bits), VertexData...

They're compressed relative to the bounding box as provided by the node codec.
