DNAViewer

The dna_viewer contains all the needed classes for reading and creating a functional rig in Maya from the DNA file. It is organized in a way that allows every option to be configurable, so you can easily get the exact result you want.

Examples

• Generates rig and export FBX per LOD
• Propagate changes from Maya scene to dna
• Simple UI

Usage from code

There are two APIs:

• assemble
• mesh

The usage of these can be found in the dna_viewer_demo.py.

Usage in Maya

Usage in Maya is explained here

Folder structure

• builder - Contains the builder classes, which are used for easily adding configuration options and building the scene, character, meshes, etc.
• config - Contains classes that represent configuration options. These files are used for fine-tuning the options.
• const - Contains constants files used in the project.
• model - Contains the data classes used in the project.
• reader - Contains the classes that are used for reading the contents of the DNA file.
• ui - Contains the classes needed for the Maya UI.
• util - Mostly contains the classes that are wrapper classes around Maya method calls.

How it works

The general flow is the following:

The flow of the scene building process is the following:

The flow of the rig building process is the following:
