SAP – Algorithm Principle Find common pairs in all swept directions i.e. Real intersecting AABB pairs = SetX ^ SetY Pairs = SetX ^ SetY = { (1-4) }y3 251 4x
SAP - Summary To achieve linear time O(n) complexity in averagecase we must Move objects in a coherent fashion (physical motion) Use incremental sort of limits. Due to coherence most oflimits are sorted. Insert sort needs only constant swaps. Implement an efficient “pair management” i.e. fast setintersection of axis pair sets (Pairs = SetX ^ SetY ^ SetZ) Problems Since objects tend to settle down (usually along Z-axis)during the simulation, large interval clustering can happen
