elements(inBoundingRectMin:rectMax:)
Searches the tree and returns all elements found within the specified bounding region.
Declaration
func elements(inBoundingRectMin rectMin: vector_float2, rectMax: vector_float2) -> [ElementType]Parameters
- rectMin:
The corner (with the lowest x- and y-coordinate values) of the bounding region to search.
- rectMax:
The corner (with the highest x- and y-coordinate values) of the bounding region to search.
Return Value
An array of objects stored in the tree whose bounding regions overlap the specified region. The array is empty if no such objects are found.
