Member Function Documentation

data()

void * PtexReader::PackedFace::data ( )

inline

Definition at line 382 of file PtexReader.h.

References _data.

Referenced by PtexReader::readFaceData().

getData()

virtual void * PtexReader::PackedFace::getData ( )

inlinevirtual

Access the data from this data block.

If the data block is constant, getData will return a pointer to a single texel's data value.

If the data block is tiled, then getData will return null and the data must be accessed per-tile via the getTile() function.

Implements PtexFaceData.

Definition at line 388 of file PtexReader.h.

References _data.

getPixel()

virtual void PtexReader::PackedFace::getPixel ( int  u, int  v, void *  result  )

inlinevirtual

Read a single texel from the data block.

The texel coordinates, u and v, have a range of [0..ures-1, 0..vres-1]. Note: this method will work correctly even if the face is constant or tiled.

Implements PtexFaceData.

Reimplemented in PtexReader::ConstantFace.

Definition at line 384 of file PtexReader.h.

References _data, _pixelsize, and PtexReader::FaceData::_res.

getTile()

virtual PtexFaceData * PtexReader::PackedFace::getTile ( int  tile )

inlinevirtual

Access a tile from the data block.

Tiles are accessed in v-major order.

Implements PtexFaceData.

Definition at line 391 of file PtexReader.h.

isConstant()

virtual bool PtexReader::PackedFace::isConstant ( )

inlinevirtual

True if this data block is constant.

Implements PtexFaceData.

Reimplemented in PtexReader::ConstantFace.

Definition at line 383 of file PtexReader.h.

isTiled()

virtual bool PtexReader::PackedFace::isTiled ( )

inlinevirtual

True if this data block is tiled.

If tiled, the data must be access per-tile via getTile().

Implements PtexFaceData.

Definition at line 389 of file PtexReader.h.

reduce()

PtexReader::FaceData * PtexReader::PackedFace::reduce ( PtexReader *  r, Res  newres, PtexUtils::ReduceFn  reducefn, size_t &  newMemUsed  )

virtual

Implements PtexReader::FaceData.

Reimplemented in PtexReader::ConstantFace.

Definition at line 949 of file PtexReader.cpp.

References _data, PtexReader::_pixelsize, PtexReader::datatype(), and PtexReader::nchannels().

tileRes()

virtual Ptex::Res PtexReader::PackedFace::tileRes ( )

inlinevirtual

Resolution of each tile in this data block.

Implements PtexFaceData.

Definition at line 390 of file PtexReader.h.
