This is a julia package that renders spacetimes. It ought to work in arbitrary dimensions but I am first focusing on getting the package to work in spatial dimensions of 3D and 2D.
Here are example renders of a unmoving black hole (Schwarzschild black hole), Unphysical "blob/soft" matter metric, and flat space (Minkowski).
