FieldTrip [1] is a library for functional 3D graphics. It is intended
for building static, animated, and interactive 3D geometry, efficient
enough for real-time synthesis and display. Since FieldTrip is
functional, one describes what models are, not how to render them
(being rather than doing).
Surfaces are described as functions from 2D space to 3D space. As
such, they are intrinsically curved rather than faceted. Surface
rendering tessellates adaptively, caching tessellations in an
efficient, infinite data structure (from the MemoTrie library) for
reuse. Surface normals are computed automatically and exactly, using
the derivative tools in the vector-space library.
For animation or interaction, FieldTrip can be used with the Reactive
[2] library for functional reactive programming (and possibly other
animation frameworks). By design, FieldTrip is completely orthogonal
to any formulation or implementation of FRP. The reactive-fieldtrip
[3] library links Reactive and FieldTrip.
FieldTrip now has a mailing list [4] and a feature/bug tracker [5].
Sounds very interesting, but... what, no pictures? From a library
especially designed for generating pictures? :-)
