is intersect --> rectIntersect necessary? #3
Description
Is it my imagination, or is the use of this function redundant? Instead of doing all combinations of two dimensions, why not just do all three dims at the same time? Or one dimension at a time?
func rectIntersect(i1, i2 *Item, x, y Axis) bool {
d1 := i1.GetDimension()
d2 := i2.GetDimension()
cx1 := i1.Position[x] + d1[x]/2
cy1 := i1.Position[y] + d1[y]/2
cx2 := i2.Position[x] + d2[x]/2
cy2 := i2.Position[y] + d2[y]/2
ix := math.Max(cx1, cx2) - math.Min(cx1, cx2)
iy := math.Max(cy1, cy2) - math.Min(cy1, cy2)
return ix < (d1[x]+d2[x])/2 && iy < (d1[y]+d2[y])/2
}
