Member Function Documentation

getData()

virtual void* PtexReader::ConstDataPtr::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 354 of file PtexReader.h.

References _data.

getPixel()

virtual void PtexReader::ConstDataPtr::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.

Definition at line 352 of file PtexReader.h.

References _data, and _pixelsize.

getTile()

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

inlinevirtual

Access a tile from the data block.

Tiles are accessed in v-major order.

Implements PtexFaceData.

Definition at line 357 of file PtexReader.h.

isConstant()

virtual bool PtexReader::ConstDataPtr::isConstant ( )

inlinevirtual

True if this data block is constant.

Implements PtexFaceData.

Definition at line 351 of file PtexReader.h.

isTiled()

virtual bool PtexReader::ConstDataPtr::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 355 of file PtexReader.h.

release()

virtual void PtexReader::ConstDataPtr::release ( )

inlinevirtual

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

Implements PtexFaceData.

Definition at line 349 of file PtexReader.h.

res()

virtual Ptex::Res PtexReader::ConstDataPtr::res ( )

inlinevirtual

Resolution of the texture held by this data block.

Note: the indicated texture res may be larger than 1x1 even if the texture data is constant.

Implements PtexFaceData.

Definition at line 350 of file PtexReader.h.

tileRes()

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

inlinevirtual

Resolution of each tile in this data block.

Implements PtexFaceData.

Definition at line 356 of file PtexReader.h.
