Function stabilizePrincipalResult

stabilizePrincipalResult(
current: PrincipalCurvatureResult,
prev: PrincipalCurvatureResult | null,
): PrincipalCurvatureResult
Stabilize principal frame against previous:
- swap (dir1,dir2) if current dir2 matches prev dir1 better
- flip signs to keep dot(prev,cur) >= 0
- apply same operations to uvDir1/uvDir2 and k1/k2
- finally enforce orthonormal tangent pair using N x dir1 for dir2
Parameters
- current: PrincipalCurvatureResult
- prev: PrincipalCurvatureResult | null
Returns PrincipalCurvatureResult
