ManuelbastioniLAB is a free and open source plug-in for Blender for the parametric 3D modeling of photorealistic humanoid characters.
It's developed by the artist and programmer Manuel Bastioni.

Graphical interface and usability
The plugin is completely integrated in Blender. The GUI is designed to be auto-explicative and intuitive and when possible the features are designed to work with one click.
Over 90% of the character is defined with only three sliders that control age (from 18 to 80 y.o.), body mass and body tone. The character is finished with other lab tools for body and face details, poses, skin and eye shaders, animation, poses, proxy, ecc.

Technology
The software is designed as a laboratory in constant evolution and includes both consolidated algorithms as the 3D morphing and experimental technologies, as the fuzzy mathematics used to handle the relations between human paramaters, the non-linear interpolation used to define the age, mass and tone, the auto-modelling engine based on body proportions and the expert system used to recognize the bones in motion capture skeletons.
The software is written in Python and works on all the platforms supported by Blender: Windows, Osx and Linux.
All the characters use the same standard skeleton, so the poses and animation can be easily moved from a character to another.
Most of the data distributed in the package is stored using the standard json syntax.

Anatomy and mesh topology of 3D human models
ManuelbastionLAB provides two different base meshes for male and female models. Each model respects the fundamental requisites of a professional mesh, as defined by the author:
- Optimization for subdivision surfaces.
- No triangles.
- Edge loops designed for deformation during poses and animation.
- The topology permits to model the main features of bodies and faces.
- Minimal use of poles.
- Human readable topology.
- Sculpting-friendly topology.
The base humans are modelled after accurate studies of anatomy and anthropology. The lab 1.5.0 provides about 470 morphs for each human character, designed to parametrically describe most of the anatomical range in human bodies, faces and expressions. Genitalia are not present.
Anthropology and phenotypes
Concerning ManuelbastionLAB, the word phenotype is intended with the following meaning:
-
- A "phenotype" defines merely the physical appearance of a class of characters, it is not related to politics, culture, language and history. It's used to describe the variations of human traits in relation to the evolution in a specific geographical area. ManuelbastioniLAB supports the most of common human phenotypes to the extent of volumetric modelling features.
The lab provides three main classes of humans: Caucasian, Asian and Afro. For each class there is a specific set of phenotypes. Each phenotype can be loaded from the library and used as base for a custom character, or mixed with another phenotype. The available phenotypes are:
- Afro phenotypes: Afromediterranean, Afroasian, Aboriginal, African.
- Asian phenotypes: Central Asian, North Asian, East Asian, South Asian, Central American, North American.
- Caucasian phenotypes: Central European, Afrocaucasian, East European, North European, Euromediterranean, Euroartic, North West European, West Asian.
Non human models: Anime, Elves, ecc
While the lab is aimed to create realistic 3d humans based on a scientific description of the parameters, the same technology can be successfully applied to non-human characters, like fantasy creatures.
The version 1.5.0 of the lab supports three variety of anime characters: classic shojo, modern shojo and "realistic style" anime. There are also male and female elves and male dwarf. Each model has a separate set of morphs to create millions of variations.
Concerning the creation of fantasy characters, the lab supports some extra parameters for humans too, like pointed ears, special teeth, etc..
