How to calculate the Line of sight (LOS) between two points in a Eucleidean appraoch?

Details? Attempted code? Full sentences?

Details: To calculate the line of sight/distance between any 2 points in a 100*100 cm grid using Euclidean formulae approach. So, a line of sight between any two points be calculated using this approach?

How to make such within the Matlab environment? Steps: 100*100 cm grid

LOS for any two points.

[Ramesh Bala]

I think I can use euclidean distance between two points as A(x1,y1) and B(x2,y2) as d = sqrt((x2-x1)^2+(y2-y1)^2)).

But is there any meaning to Line of sight with this?

[Kaitlyn Keil]

Line of sight doesn't matter unless you have some sort of obstacle or direction to something else. Are there objects on the grid besides the 2 points?

[Ramesh Bala]

Yeah some times a hole ,or some mass in between.

Assuming you know the coordinates of all the points and obstacles (and holes?), you can follow the below steps.

Points P1(x1,y1) and P2(x2,y2). Let obstacle be O(x3,y3).

Check the distance between P1 and P2. Compare it with that of P1->O + O->P2. if both are the same, them O lies between P1 and P2 and is in LoS.

Euclidean distance between two points -> sqrt((x2-x1)^2+(y2-y1)^2))

Alright ! lemme give a try
