Module blended 

Structs

BlendedSpace

Metric g = (1 − α)·g_A + α·g_B, with a spatially varying BlendingField.

GeodesicLog

GeodesicState

LinearBlendX

C² quintic smootherstep along x.

Enums

GeodesicError

LogError

Constants

BLENDED_E3_H3_WGSL_RESIDUAL

GEODESIC_DEFAULT_STEPS

GEODESIC_ERROR_BUDGET

Maximum accepted heuristic from metric-scaled RK4 step doubling.

LOG_MAX_ITERS

LOG_RESIDUAL_TOL

Euclidean threshold on the residual |to − exp_from(v)|.

Traits

BlendingField

weight is 0 for pure A and 1 for pure B, and must be C¹: the integrator differentiates it.

ConformallyFlat

g_ij(p) = f(p)·δ_ij in the chart Space::Point carries, not in some other chart.

Functions

gauss_newton_log

Solves exp_from(v) ≈ to; failure returns the last finite iterate.

gauss_newton_log_checked

gauss_newton_log with its failure reported instead of hidden; the vector is still the last finite iterate.

geodesic_log_checked

integrate_geodesic_frame_checked

integrate_geodesic_frame_to_checked

rk4_geodesic
