TriangleCodecIndexed8BitPackSOA4Flags Class Reference

#include <TriangleCodecIndexed8BitPackSOA4Flags.h>

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
 
class  ValidationContext
 This class is used to validate that the triangle data will not be degenerate after compression. More...
 
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.
