Smith.Assembly.Frame (Smith v0.1.0)

Copy Markdown View Source

Rigid-frame arithmetic used by assembly placement and joint evaluation.

This implementation module uses the same right-handed frame maps as Smith.Plane: an origin and unit u, v, and n axes. Geometry stays in OCEx; these functions only compose coordinates and produce rotation/translation options. Use Smith.Assembly and Smith.Plane to define a public model.

Summary

Types

t()
vector()

Functions

compose(a, b)

Composes frames, applying the second frame before the first.

identity()

Returns the identity frame at world zero.

inverse(f)

Returns the inverse of a normalized rigid frame.

options(f)

Converts a rigid frame to OCEx-compatible rotation-then-translation options.

placement(opts)

Builds a frame from validated assembly rotation and position options.

Types

t()

@type t() :: %{origin: vector(), u: vector(), v: vector(), n: vector()}

vector()

@type vector() :: {number(), number(), number()}
