Member Function Documentation

◆ addMetaData()

void PtexWriterBase::addMetaData	(	const char *	key,
		MetaDataType	t,
		const void *	value,
		int	size
	)

protectedvirtual

Reimplemented in PtexMainWriter.

Referenced by PtexMainWriter::addMetaData(), and writeMeta().

◆ calcTileRes()

Ptex::Res PtexWriterBase::calcTileRes ( Res faceres )

protected

Definition at line 570 of file PtexWriter.cpp.

References _pixelSize, PtexUtils::floor_log2(), PtexUtils::min(), and TileSize.

Referenced by writeFaceData().

◆ close()

bool PtexWriterBase::close ( Ptex::String & error )

virtual

Close the file.

This operation can take some time if mipmaps are being generated or if there are many edit blocks. If an error occurs while writing, false is returned and an error string is written into the error parameter.

Implements PtexWriter.

Reimplemented in PtexIncrWriter, and PtexMainWriter.
