Object Section 

Mesh / ArtMesh

A set of triangles composed of vertices and lines is called a “mesh.”
PSD images loaded into Modeling View are always placed on the canvas with this “mesh” assigned.
An image with the mesh assigned is the “ArtMesh.”

Manual page: About ArtMesh

Polygon / Vertex / Edge

The triangles of a mesh, which is a set of triangles composed of vertices and lines, are called “polygons.”
The white points of a mesh are called “vertices.”
The lines of a mesh are called “edges.”

Deformer (warp deformer, rotation deformer)

A container in which the vertices of an ArtMesh can be deformed and moved together is called a “deformer.”
There are two types of deformers: “Warp deformers,” which can create curved shapes, and “rotation deformers,” which can rotate and scale.
Each can do different things, so they are used for different purposes.

Manual page: About Deformer


Each element placed on the canvas, such as an ArtMesh or deformer, is called an “object.”

Parameter Section


Parameters” can be used to store the deformation, position, etc. of an object.

Manual page: About Parameters

Key / Keyform

The point on the parameter where the shape is stored is called the “key.”
The shape specified by a key is called a “keyform.”

Manual page: Edit Parameters



Groups of characters divided by their components (eyes, nose, etc.) are called “Parts.”
Parts” are displayed in the Parts palette section.

Manual page: About Parts

Draw order

The value that specifies the order in which the ArtMeshes overlap is called the “draw order.”
It can be set between 0-1000. The larger the value, the more the ArtMesh will be displayed in front.

Manual page: About Draw Order

Texture Atlas

The image showing ArtMeshes side-by-side is called a “texture atlas.”
Typically, the format is PNG and the image size is created as n squares of 2.

This is required when exporting models for embedding in the SDK or for Cubism 2.1.
(Not required for video applications.)
