Lets say I have 2 points (x1,y1) and (x2,y2). And I can draw vector from point (x1,y1) to point (x2,y2). How can I get all possible points between them at for example every 10 pixels?
Simple visualization:
The vector between point A and a point B is B-A (x2-x1, y2-y1)
If you normalize that vector, and multiply it by the factor you want (it seems you want a distance of 10px, so your factor is 10), you can get all the points by adding it to the a current point (which initially is the origin A) until you reach the end point B.
