Detailed Description

This is a base class for both FltFace and FltMesh, which are two different kinds of geometric primitives that might be encountered in a MultiGen file.

They have similar properties.

bool FltGeometry::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 FltBeadID.

Reimplemented in FltFace, and FltMesh.

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

Fills in the information in this bead 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 FltBeadID.

Reimplemented in FltFace, and FltMesh.

LColor FltGeometry::get_alt_color ( ) const

If has_alt_color() indicates true, returns the alternate color of the face, as a four-component value (including alpha as the transparency channel).

Definition at line 163 of file fltGeometry.cxx.

References FltHeader::get_color(), and has_alt_color().

LRGBColor FltGeometry::get_alt_rgb ( ) const

If has_alt_color() indicates true, returns the alternate color of the face, as a three-component value ignoring transparency.

Definition at line 178 of file fltGeometry.cxx.

References FltHeader::get_rgb(), and has_alt_color().

LColor FltGeometry::get_color ( ) const

Returns the primary color of the face, as a four-component value (including alpha as the transparency channel).

If has_color() is false, the result is white, but still reflects the transparency correctly.
