Member Function Documentation

bool FltTransformScale::build_record ( FltRecordWriter &  writer) const [protected, virtual]

Fills up the current record on the FltRecordWriter with data for this record, but does not advance the writer.

Returns true on success, false if there is some error.

Reimplemented from FltRecord.

Definition at line 143 of file fltTransformScale.cxx.

bool FltTransformScale::extract_record ( FltRecordReader &  reader) [protected, virtual]

Fills in the information in this record based on the information given in the indicated datagram, whose opcode has already been read.

Returns true on success, false if the datagram is invalid.

Reimplemented from FltRecord.

bool FltTransformScale::has_center ( ) const

Returns true if the center is specified, false if it is not.

For some reason, MultiGen stores large negative numbers in for the center if it is not specified. It is unclear what the purpose of this is.

static void FltTransformScale::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from FltTransformRecord.

void FltTransformScale::set ( const LPoint3d &  center,
const LVecBase3f &  scale 
)

Defines the scale.
