scene:window-of

(scene:window-of v)

The NSWindow the viewer draws into -- the escape hatch to appkit: and to raw objc:send for anything the viewer does not offer. Part of the scene package, a 3-D viewer for geom solids written in rontolisp over metal and appkit and loaded on first use: macOS (java -jar, the rontolisp binary, or a compiled .class / .jar; never a .wasm), with a display. See the solid modeling guide.
