FreeSG ("Free" as in "Free software" and "Free of bloat")
is an compact, general-purpose, open-source scene-graph library. It implements
a generic, extensible object/scene representation, designed to simplify such
tasks as real-time rendering and geometrical queries.
One feature which distinguishes FreeSG from the variety of scene-graph
libraries available is its ability to solve systems of logical (geometrical)
constraints such as angles and distances, in order to define the relationship
between elements of a scene, in a powerful and unambiguous way.
FreeSG depends on the
Agar
library, and it released under the same
revised BSD license.
FreeSG and its related projects are sponsored by
Csoft.net:
Security conscious, high-availability Unix hosting on redundant server
arrays.
Parts of the library are still considered beta, and FreeSG is undergoing
active development.
We hope to release the first stable version before August 2009.
The FreeSG distribution includes three libraries: SG (3D scenes),
SK (2D sketches) and MAP (tiling).

The SK ("sketch") library provides support for dimensioned 2D vector drawings
(or sketches). This includes an Agar-GUI widget for visualization
and edition of sketches. The constraint solving system greatly improves
the efficiency of the user interface, and enables dimensions to be
specified in a parametric fashion.
|
The SG ("scene graph") library aims at implementing a set of efficient,
generic scene rendering / geometrical query algorithms where the speed and
memory tradeoffs can be adjusted to the widest possible range of
applications and platforms.
Using a simple, extensible scene description language, applications using
SG can create hierarchical scenes composed of objects (e.g., polyhedrons,
viewpoints, light sources). The relationship between those objects can be
expressed in terms of standard transformation matrices, or geometrical
constraints.

"The idea is if you use those two shapes and try to colour the plane with
them so the colours match, then the only way you can do this is to produce
a pattern which never repeats itself."
