/**
|
||||
* Provide a fast test for point inside polygon.
|
||||
*
|
||||
* Takes a large poly and splits it into a grid of rectangular cells, forming a spatial hash table.
|
||||
* Each cell contains only the edges that 'touch it' (any point of the edge belongs to the cell).
|
||||
* Edges can be marked as leading or trailing. Leading edge indicates that space to the left of
|
||||
* it (x-wise) is outside the polygon. Trailing edge, conversely, means space to the right is
|
||||
* outside the polygon.
|
||||
*
|
||||
* The point inside check for point (p) works as follows:
|
||||
* - determine the cell coordinates of (p) (poly2grid)
|
||||
* - find the matching grid cell ( O(0), if the cell coordinates are outside the range, the point
|
||||
* is not in the polygon ).
|
||||
* - if the cell contains edges, find the first edge to the left or right of the point, whichever
|
||||
* comes first.
|
||||
* - if the edge to the left is the 'lead edge', the point is inside. if it's a trailing edge, the
|
||||
* point is outside.
|
||||
* - idem for the edge to the right of (p), just reverse the edge types.
|
||||
* - if the cell doesn't contain any edges, scan horizontal cells to the left and right (switching
|
||||
* sides with each iteration) until an edge if found.
|
||||
*
|
||||
* @note: The rescale_trunc() function is used for grid<->world coordinate conversion because it
|
||||
* rounds towards 0 (not to nearest). It's important as rounding to nearest (which the
|
||||
* standard rescale() function does) will shift the grid by half a cell.
