## Member Function Documentation

## ◆ baseExtraMemUsed()

size_t PtexReader::TiledFaceBase::baseExtraMemUsed | ( |  | ) |
| inline protected

Definition at line 450 of file PtexReader.h.

References _tiles.

Referenced by PtexReader::TiledFace::memUsed(), and PtexReader::TiledReducedFace::memUsed().

## ◆ getData()

virtual void* PtexReader::TiledFaceBase::getData | ( |  | ) |
| inline virtual

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 440 of file PtexReader.h.

## ◆ getPixel()

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

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.

Definition at line 1104 of file PtexReader.cpp.

## ◆ isConstant()

virtual bool PtexReader::TiledFaceBase::isConstant | ( |  | ) |
| inline virtual

True if this data block is constant.

Implements PtexFaceData.

Definition at line 438 of file PtexReader.h.

## ◆ isTiled()

virtual bool PtexReader::TiledFaceBase::isTiled | ( |  | ) |
| inline virtual

True if this data block is tiled.

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

Implements PtexFaceData.

Definition at line 441 of file PtexReader.h.

|  | Res | newres,
|  | PtexUtils::ReduceFn | reducefn,
|  | size_t & | newMemUsed

## ◆ release()

virtual void PtexReader::TiledFaceBase::release | ( |  | ) |
| inline virtual

Release resources held by this pointer (pointer becomes invalid).

Reimplemented from PtexReader::FaceData.

Definition at line 437 of file PtexReader.h.

## ◆ tileRes()

virtual Ptex::Res PtexReader::TiledFaceBase::tileRes | ( |  | ) |
| inline virtual

Resolution of each tile in this data block.
