Standard Library Functions

Built-in functions available in the default scope or via import "std".

Math

• sin(rad), cos(rad), tan(rad)
• asin(v), acos(v), atan(v)
• sqrt(n), abs(n), pow(n, exp)
• min(a, b), max(a, b)
• floor(n), ceil(n), round(n)
• PI: Constant (3.14159...)

Collections

• avg(array): Returns average of numbers.
• print(args...): Prints to console.
• Grid(start, step, count): Generates an arithmetic sequence.

Array Methods

• array.fold(reducer, initial): Reduces array to single value.
• array.map(lambda): Transforms each element.
• array.filter(lambda): Selects elements.
• array.count / array.length: Number of elements.

import "std"

sum := (1..10).fold((acc, x) => acc + x, 0)

Geometry Constructors

Primitives

• Vector(x, y, z): Creates a Vector.
• Point(x, y, z): Creates a Point.
• Normal(elev, index): Creates a normal Vector from machine angles (elevation, index). Requires Gear().
• Normal(elev, azim): Creates a normal Vector from spherical coordinates (elevation, azimuth).
• Plane(normal, dist): Creates a Plane.
• Line(origin, dir): Creates a Line.

Solids

• Cube(size): Creates a Cube centered at origin.
• Octahedron(size): Creates an Octahedron.
• Hull(geometry...): computes the convex hull of the provided points/planes.

Symmetry

• Rotate(axis, order): Creates a rotational symmetry group of order n around axis.
• Mirror(plane): Creates a reflection symmetry group across plane.

Global Configuration

• Gear(n): Sets the index gear (e.g., 96). Enables Index Mode.
• RI(n): Sets the Refractive Index.
• Mode(s): Sets the angle mode ("deg" or "index").
