I have a simple coordinate system like the following:
In this example, I have a line between two coordinates $(2,7)$ and $(8,5)$. The line is drawn from and to the exact center of each coordinate.
I'd like to calculate what coordinates are intersected by this line. Formulated differently: I need to know which coordinates the line touches.
Using the above coordinate system, a correct result would be:
$(2,7)\rightarrow(3,7)\rightarrow(4,6)\rightarrow(5,6)\rightarrow(6,6)\rightarrow(7,5) \rightarrow(8,5)$
The selected coordinates are just random, I'd like to be able to do the calculation no matter what two coordinates are selected.
Thanks in advance!
