radiansToPointAnd2Derivatives Method

Evaluate a point and derivatives wrt to theta, phi, thetaTheta, phiPhi, and thetaPhi. All outputs are to caller-allocated points and vectors.

radiansToPointAnd2Derivatives(thetaRadians: number, phiRadians: number, point: Point3d, d1Theta: Vector3d, d1Phi: Vector3d, d2ThetaTheta: Vector3d, d2PhiPhi: Vector3d, d2ThetaPhi: Vector3d): void

Parameter Type Description
thetaRadians number longitude, in radians
phiRadians number latitude, in radians
point Point3d (returned) surface point
d1Theta Vector3d (returned) derivative wrt theta
d1Phi Vector3d (returned) derivative wrt phi
d2ThetaTheta Vector3d (returned) second derivative wrt theta twice
d2PhiPhi Vector3d (returned) second derivative wrt phi twice
d2ThetaPhi Vector3d (returned) second derivative wrt theta and phi

Returns - void
