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
