FOS - Free on Shades

News: Working on major update of Fos. Stay alert :)))

Fos is a novel scientific visualization platform written in Python.

Fos provides

• a lightweight module for 3D renderings
• easy-to-use actors for presenting data
• clearly written and explained code
• a natural home for collaboration

Fos is based on Python, Numpy, Cython, OpenGL and PySide.

Find the source code on GitHub

Contents:

Actors

Fos includes various actors (visualization objects) for visualization. They expose an easy interface for creation, usually using Numpy arrays. Two classes of actors are defined:

Static actors

For static structures that do not evolve in time.

Dynamic actors

One, or more parameters can have a time dimension, making the actor evolving dynamically.

Static actors

AttributeNetwork

ConnectedSlices

Surface

InteractiveCurves

NeuronRegion

SphereCloud

Polygon Mesh Processing

Geometry processing: surface reconstruction from point samples, filtering operations for noise removal, geometry analysis, shape simplification, geometric modelling. queries: e.g. p e R3. Is it inside or outside? distance from p to surface http://cgal.org http://openmesh.org http://meshlab.org
