Reactor

FusionTwin renders its first complete reactor vessel — plasma, coils, and a sense of confinement. Next up, the divertor.

First rendered FusionTwin reactor — plasma nested inside toroidal copper and gold coils

After Embryo's single sphere and Birdcage's accidental detour, FusionTwin now has its first honest reactor form.

The plasma sits at the center — a cool blue oblate core surrounded by the copper coil arrangement. Two gold rings wrap the vessel, giving the whole thing the first hint of a tokamak silhouette. It is still a sketch, but it is unmistakably a fusion reactor now.

What this proves:

The renderer can handle layered geometry.
The coil system can be visualized as a real 3D structure.
Plasma, coils, and containment can coexist in one scene.

The next piece is the divertor — the bottom-facing armor that siphons off exhaust and keeps the plasma clean. Without it, this is a pretty picture. With it, the model starts meaning something physically.

Divertor next.
