# Get a coordinate between to points

#1

Hello,

i am currently working on a script where i need to place vertices on the straight line between two points.
The vertices need to be placed not only at the centerpoint, but at any position on this line i specify.

I tried lots of things, but i can only get it to work right with the center value strangely, which looks like this:

``````
#Get Coordinate at between two coordinates according to a factor
def get_point_inbetween(self,obj_1_ws_coords, obj_2_ws_coords, summand ):

#Calculation
coord_x = (obj_1_ws_coords[0] + obj_2_ws_coords[0]) / 2 +  summand
coord_y = (obj_1_ws_coords[1] + obj_2_ws_coords[1])  / 2 +  summand
coord_z = (obj_1_ws_coords[2] + obj_2_ws_coords[2])  / 2 +  summand

return [coord_x, coord_y, coord_z]

``````

Only when summand is 0 it works properly…but summand is ment to be a value letting me “slide” along the line!

Anybody an idea how to achieve the correct result?

I found out:

``````
#Get Coordinate at between two coordinates according to a factor
def get_point_inbetween(self,obj_1_ws_coords, obj_2_ws_coords, factor ):

#Calculation
coord_x = obj_1_ws_coords[0] + factor  *(obj_2_ws_coords[0] - obj_1_ws_coords[0])
coord_y = obj_1_ws_coords[1] + factor  *(obj_2_ws_coords[1] - obj_1_ws_coords[1])
coord_z = obj_1_ws_coords[2] + factor  *(obj_2_ws_coords[2] - obj_1_ws_coords[2])

return [coord_x, coord_y, coord_z]

``````

…does the job for me!
