Ok, I also know this if non-Gundam subject, but here it goes -

Dyson Sphere you say? In the TNG Epi... "Relics"??????? It is a gigantic
sphere about 200 km in diameter encapsuling the entire star. Inner surface
of the structure is hospitable and equals surface area of thousands of M
class (Earth Like) planet. The postulate (by the person called Dyson
obviously) based on postulate that a star could be encased to conserve and
exploit every joules of energy emitted by the star every second. Here's the
resources I found:

Escher Dyson Sphere
-
A sufficiently advanced race who wanted to maximize real estate
and utilize all of their star's radiant energy might build a sphere around
their sun.
This notion has been called a Dyson Sphere
-
At the equator a spinning sphere would have enough angular momentum
to offset the star's gravity, but the poles would be prone to collapse.
-
One way to address this would be a series of Larry Niven type ring worlds
tilted at different angles to the plane of ecliptic.
-
The M. C. Escher's Concentric Rinds intersect,
sometimes three rings at a juncture, sometimes four.
Even so, I believe Escher's print looks like a multi-ringworld system.

Exterior Surface Portal Exterior Portal Interior

The Dyson Sphere was constructed over a million years ago by an unknown
race, and abandoned several thousand years ago, presumably due to
instability in the central star. The carbon-neutronium shell is
approximately 2500 metres thick, and is presumed to contain circulation
equipment for the Class-M environmental systems as well as artificial
gravity and power generators, but this is an as-yet untested hypothesis,
since no access has been gained and sensors are unable to penetrate the
material. A system of plates orbiting the central star provides an
artificial day/night cycle.

Externally, the sphere is made up of rectangular panels. About two thirds of
these measure 601 by 826 metres, and the remaining third measure 601 by 413
metres. Entry to the sphere is by means of twenty symmetrically-spaced 3000
metre wide octagonal portals. These portal are currently automatically
operated, and are triggered by any sensor or communications signal directed
toward it. They then use massive tractor beams to draw vessels inside. Due
to the incompatibility of the Sphere's systems with those of Federation
ships, standard procedure is for a ship to shut down all systems before
transmitting a signal, in order to avoid overloads. Since no access has yet
been gained to the control systems, a ship cannot open the portal from the
inside, so a second ship must trigger it from the outside, standing off
500,000km to avoid being drawn in itself.

For mapping purposes, the Sphere has been divided into twenty equal areas,
roughly triangular, with an entrance portal at each corner. Each triangle
covers an area of 6.28x1016km2 and is approximately 118,000,000km on a side.
The portal at the north pole of the Sphere (relative to the star's north
magnetic pole) is designated N0, and the five portals around the 30th
northern parallel are designated N1 through N5. The South polar portal is
degnated S0 and those around the 30th southern parallel are S1 through S5.

Several large bodies of water have been spotted, as well as wilderness areas
and what appear to be large-scale industrial areas. No exploration has as
yet been conducted. It is unknown whether any sapient life forms exist
within the sphere, but none were detected by the Enterprise-D during its
time inside the sphere.

And for the Energy to matter conversion -
If you are talking about something like Star Trek's Holodeck or Replicator,
it's not much of energy-to-matter conversion. Sure, to convert and arrange
any matter in certain shape costs energy, but direct energy to matter is not
that talked about in the series either.

Replication process goes like this -
Recycling of matter ->
Transportation of Recycled Mass (meaning simplified, back to element) to the
assembly point ->
Replication by arranging the recycled mass with transporter buffer
arrangement sequence. ->
Recycling of Matter when a person is done with thing. Ad infinitum.

So, as law of conservation of matter would dictate, if you take the brick
and break them into tiny pieces, they still weigh same, and if you can
somehow rearrange them into bricks, they should weigh the same. Although the
recycled mass would weigh just the same as the end product, the process of
breaking down carefully is the key to the all thing, since replicators won't
just make same thing over and over, they have different replication sequence
for all sort of things, like - Clothings, Foodstuff, Phase inducers,
whatnot. They have base elements (whatever they are) in their composition,
but in certain arrangement . So the recycled matter must been stored in
catagorized way (i.e. carbon only, hydrogen only, and they would be all
separated somehow). And used later on with buffer sequence.

For the holodeck, it is continuous cycle of replication process and correct
use of force field put together. I don't know how force field works, but it
would be something like -
spraying of minute subatomic particles ->
Charging them with burst (or continuous pulse) of energy ->

That's about it.
