MOUTH SHAPE 3D DEFINITION FILE FORMAT

File Format Name: Mouth Shape 3D Definition
File Type: Ascii Text (*.txt)
Code: SLMS3D
Version: V1
Last Update: Feb. 17, 2006

This file format defines the mouth shapes displayed in the Spectralipz software. This is used in the menu option FILE -> IMPORT -> MOUTH SHAPE DEFINITION. There are two types of mouth shapes that can be defined, 2D which consists of a list of images and 3D which consists of a mesh and morphshapes. This file describes the 3D type.

A 3D mouth shape definition is composed of a camera, mesh and morph shapes definition and optionally a texture image file. The definition file and texture image file muse be located in the same directory.

The 3D Mouth Shape Definition File

This file format is composed of lines of plain ASCII text. Each line is terminated with CR/LF (carriage return/line feed). This file can be viewed or edited by any plain text editor (e.g. Windows NotePad). The file's default extension is ".txt"

The first two lines of the file should always be the following. This merely states the file type and the version.

The following is the structure of the file.
