Expand description
Exact, format-neutral curve representations and evaluation contracts.
Composite, trimmed, offset, and surface-bound curves are graph relations in
axiolid-model; keeping them there avoids a curve/surface dependency cycle.
The pieces of atomic curves such a relation runs along are a neutral value
here, CurvePath, which an evaluator measures (#290).

Modules§
- banked
- A centreline carrying a roll about its tangent: cant, bank angle and the point the section rotates about.
- chain
- Arc-length chains: plane curves parameterised by cumulative arc length, built from pieces placed rigidly end to end.
- conic
- Exact conic curve data.
- elevation
- Elevation laws and the composition of a planar curve with one.
- evaluate
- Backend-open curve evaluation capability.
- implicit
- Curves given implicitly: where a field over a surface’s parameters is zero (ADR 0077).
- linear
- Linear curve values.
- linear_
vocabulary - The focused linear vocabulary, re-exported for consumers that want to name
its origin explicitly. A line-only consumer should depend on
axiolid-lineardirectly instead of paying for this aggregate. - pair_
section - Where two parametric surfaces meet, carried by nodes on both (ADR 0077).
- path
- Pieces of curves laid end to end: the neutral form of a curve relation a distance runs along (#285, #290, ADR 0082).
- quadric_
section - Where a quadric cuts a cylinder or cone, read in the ruled surface’s own parameters (ADR 0076).
- seam
- Which side of a seam a position on it is read from (#263).
- sinusoid
- The height wave a plane cuts across a cylinder, in the cylinder’s own parameters.
- spline
- B-spline and rational B-spline curve data.
- spline_
surface - Polynomial and rational B-spline surfaces.
- torus_
section - Where a plane or sphere cuts a torus, read in the torus’s own parameters (ADR 0076).
Structs§
- Harmonic
- One sinusoidal term of a curvature law:
amplitude * sin(angular_frequency * s + phase). - Intrinsic2
- A plane curve given by its natural equation: a curvature law anchored to a start frame and run for a finite arc length.
- Intrinsic3
- A space curve given by its natural equations.
- Line
- Infinite parametric line
origin + t * direction. - Polyline
- Piecewise-linear curve preserving source vertex order.
Enums§
- Curvature
Law - Curvature as a closed-form function of arc length.
- Curve2
- Atomic two-dimensional curve values.
- Curve3
- Atomic three-dimensional curve values.
