Set the GL viewport.

Initialize OpenCSG's internal GL loader. Call once after GL context is current.

Convert a Lua arguments table `{ positional..., named_key = val, ... }` into an OpenSCAD argument string like `[10, 20], fillet = 2, center = true`.

Convert a Lua table to an OpenSCAD array like `[1, 2, 3]`. Only processes sequential integer keys (the array portion).

Create a Lua closure that wraps a BOSL2 function call. The generated function accepts a Lua table of arguments and converts them to an OpenSCAD call

Compute a rounded cuboid mesh via Manifold's Minkowski sum of an inner box with a sphere. Same approach OpenSCAD uses for Minkowski preview: compute t

Ensure `self.mesh` is populated by evaluating the ScadNode tree if needed. After this call, `self.mesh` is guaranteed to be `Some`.

Materialize a Manifold's mesh into SmoothTriangles.

Build an octahedron as a polyhedron.

Paint a Lucide icon into a given rect, scaled to fit. The icons are drawn as strokes in a 24x24 coordinate system.

Parse cube() arguments: supports all LuaCAD forms. Returns (w, d, h, center).

Returns (r1, r2, height, segments, center).

Parse a hex color string (`#RGB`, `#RRGGBB`, `#RGBA`, `#RRGGBBAA`). Returns the RGB components; alpha is ignored for now since the color representatio

Returns (radius, segments).

Project a world position to pixel coordinates (physical pixels, y from bottom).

Free an OpenCSG primitive. # Safety `prim` must be a valid handle returned by `primitive_new`.

Create a new OpenCSG primitive. # Safety `callback` will be invoked by OpenCSG during rendering passes. `user_data` must remain valid for the lifetim

Build a prismoid (rectangular frustum) as a polyhedron.
