Fields¶

Precision¶

PrecisionProfile ludus::foundation::geometry::FramePreparation::Precision = PrecisionProfile::Visual

Strict is rejected with UnsupportedPrecision: frame angular error is Estimated (ADR 0024).

SeedUp¶

math::Vector3d ludus::foundation::geometry::FramePreparation::SeedUp {}

Up direction projected onto the first normal plane.

Related types: math::Vector3d

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/frame.hpp

SeedPolicy¶

FrameSeedPolicy ludus::foundation::geometry::FramePreparation::SeedPolicy = FrameSeedPolicy::RejectDegenerateSeed

Degenerate-seed handling.

FallbackAxis¶

math::Vector3d ludus::foundation::geometry::FramePreparation::FallbackAxis {}

Deterministic fallback; used only by UseFallbackAxis.

Related types: math::Vector3d

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/frame.hpp

MinimumSinAngle¶

float64 ludus::foundation::geometry::FramePreparation::MinimumSinAngle = 0.0

Dimensionless in [0,1): a seed whose sine with the tangent is at or below this is degenerate. A corner rotation is undefined when the cosine of half its angle is at or below it.

MinimumSpeed¶

float64 ludus::foundation::geometry::FramePreparation::MinimumSpeed = 0.0

Asset units per unit u; finite and >= 0. The tangent is undefined at or below it.
