Introduction

This module contains some basic mathematical and physical algorithms

Available Classes and Functions

Function G_Force():

Get two planets' gravity force

Parameters:

• m1,m2: the mass of two planets
• pos1,pos2: the PCI coordinate position of two planets, in the form of list [x,y,z]

Return:

• The gravity force of two planet, in the form of nparray [fx,fy,fz]
• If two planets too close to get result, None is returned

Function Vec_Project():

Project the 2nd vector to 1st vector

Parameters:

• vec1: the vector selected as base, in the form of list [x,y,z]
• vec2: the vector need to be projected, in the form of list [x,y,z]

Return:

• The projected vector, in the form of nparray [x,y,z]

Function AngleXYZ():

Get the angle between the vector and specified plane

Parameters:

• plane: 'XY','YZ','XZ' available

Return:

• The angle in degree

Function Vec_Length():
