Determine if point is within bounding box


How would you determine if a given point is within the bounding box?

My point is 48.847172 , 2.386597.

Boundingbox:

    "48.7998602295",
    "48.8198640442",
    "2.46138595581",
    "2.48138619423"

Solution

  • Do just as usual:

    if( bb.ix <= p.x && p.x <= bb.ax && bb.iy <= p.y && p.y <= bb.ay ) {
        // Point is in bounding box
    }
    

    bb is the bounding box, (ix,iy) are its top-left coordinates, and (ax,ay) its bottom-right coordinates. p is the point and (x,y) its coordinates.
