References _tiles.

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

◆ getData()

virtual void* PtexReader::TiledFaceBase::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 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.

References PtexFaceData::getPixel().

◆ isConstant()

virtual bool PtexReader::TiledFaceBase::isConstant ( )

inlinevirtual

True if this data block is constant.

Implements PtexFaceData.

Definition at line 438 of file PtexReader.h.

◆ isTiled()

virtual bool PtexReader::TiledFaceBase::isTiled ( )

inlinevirtual

True if this data block is tiled.

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

Implements PtexFaceData.

◆ release()

virtual void PtexReader::TiledFaceBase::release ( )

inlinevirtual

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 ( )

inlinevirtual

Resolution of each tile in this data block.
