The system is based on a client-server model that provides remote authentication and task scheduling besides the distributed and/or parallel fields computation. By now the followings are the features implemented:

- Fields visualisations:
- Electric potential
- Electric field intensity
- Electric field vectors
- Flowlines
- Flowlines with
*Line Integral Convolution (LIC)*

- Visualisations blending
- Explorer charges simulation
- Computation features:
- Distributed and/or parallel fields simulation
- Remote simulations sheduling
- Stop/Pause/Resume of jobs
- Remote users authentication over
*MySQL* - Real-time fields compression with
*MiniLZO* - Motif based GUI

VecMetaFrame takes as input a bitmap made by the user, which represents the distribution
of conductors over the surface:
a red/blue pixel means a positive/negative point, a black pixel means a zero potential point while a white pixel means
the point have to be calculated.

The potential values assigned to conductors are proportional to the red/blue RGB value (from 0 to +/-1.0 V), therefore
pixels with an ambiguous color must be avoided.

After the conductors loading, the potential values can be modified using the "Set conductors" option or,
instead, the simulation can be directly started connecting to the *VMF server*.

Visualisations

Available visualisations:

These examples suppose an electric tripole as input.

Other features

Field calculous

The Nature imposes the electrostatic potential within the empty space have to be an armonic
field, which obeys to the *Laplace* equation:

Thus, it can be calculated using the*Jacobi*
itaration method,
which consists in a infinite calculous of a potential average in every single field point.

The computation therefore is theoretically infinite, however after a sufficent amount of time the simulation result is reasonably near to the theoretic edge.

Development

VMF is a direct child of *Nablakiller* and
*Flooxd*, it is developed by \\HiFi\\ and Altivec ( [hifi_AT_metalabs_DOT_org] | [altivec_AT_metalabs_DOT_org] )
and must be considered a still-in-development project, for these reasons advertises and corrections are appreciated.

VecMetaFrame is a MeTA~LAbS project [ www.metalabs.org ] and it's obviously distributed under the GPL licence.
