drawer

Single light drawer.
Parameter:
sphere : One of the intersectionElements class. Define the sphere with certain radius and center
incident_light : One of the intersectionElements class. see Elements about light
refraction_index : the refraction index of the paticle
start_point : The coordinates of the starting point. Tuple or list contains three float numbers
intersection_time ; Times of the intersection, How many times the light intersect the sphere

Return:
dict
points: the intersection points list first intersection: points[0] second intersection point: points[1] etc.
lines: the lines to draw in the figre list

multi_line_drawer
