Detailed Description

template<typename T>
class UT_VoxelTileCompress< T >

UT_VoxelTileCompress

A compression engine for UT_VoxelTiles of a specific type. This is a verb class which is invoked from the voxeltile class.

Constructor & Destructor Documentation

template<typename T>
UT_VoxelTileCompress< T >::UT_VoxelTileCompress ( )
inline

Definition at line 123 of file UT_VoxelArray.h.

template<typename T>

Member Function Documentation

template<typename T>
virtual bool UT_VoxelTileCompress< T >::canSave ( ) const
inlinevirtual

Does this engine support saving and loading?

Definition at line 154 of file UT_VoxelArray.h.

template<typename T >
void UT_VoxelTileCompress< T >::findMinMax ( const UT_VoxelTile< T > &  tile,
T min,
T max 
) const
virtual

Determines the min & max values of the tile. A default implementation uses getValue() on all voxels.

template<typename T>
virtual int UT_VoxelTileCompress< T >::getDataLength ( const UT_VoxelTile< T > &  tile) const
pure virtual

Returns the length in bytes of the data in the tile. It must be at least one byte long.

template<typename T>
virtual const char* UT_VoxelTileCompress< T >::getName ( )
pure virtual

Returns the unique name of this compression engine so we can look up engines by name (the index of the compression engine is assigned at load time so isn't constant)

template<typename T>
virtual T UT_VoxelTileCompress< T >::getValue ( const UT_VoxelTile< T > &  tile,
int  x,
int  y,
int  z 
) const
pure virtual

Reads directly from the compressed data. Cannot alter the tile in any way because it must be threadsafe.

template<typename T>
virtual bool UT_VoxelTileCompress< T >::isLossless ( ) const
inlinevirtual

Returns true if the compression type is lossless.

UT_VoxelTile< T > &  tile

template<typename T>
virtual bool UT_VoxelTileCompress< T >::load ( UT_JSONParser p,
UT_VoxelTile< T > &  tile 
) const

template<typename T>
virtual void UT_VoxelTileCompress< T >::save ( std::ostream &  os,
const UT_VoxelTile< T > &  tile 
) const
inlinevirtual

template<typename T>
virtual bool UT_VoxelTileCompress< T >::save ( UT_JSONWriter w,
const UT_VoxelTile< T > &  tile 
) const
inlinevirtual

template<typename T>
virtual bool UT_VoxelTileCompress< T >::tryCompress ( UT_VoxelTile< T > &  tile,
const UT_VoxelCompressOptions options,
T  min,
T  max 
) const
pure virtual

Attempts to compress the data according to the given tolerance. If succesful, returns true.

template<typename T>
virtual bool UT_VoxelTileCompress< T >::writeThrough ( UT_VoxelTile< T > &  tile,
int  x,
int  y,
int  z,
T  t 
) const
pure virtual

Attempts to write data directly to the compressed tile. Returns false if not possible.
