Many techniques have already been proposed to improve the efficiency of maximum intensity projection (MIP) volume rendering, but none of them considered the possible hypothesis of a better complexity than either O(n) for finding the maximum value of n samples along a ray or O(n3) for an object-order algorithm. Here, we fully model and analyze the use of octrees for MIP, and we mathematically show that the average MIP complexity can be reduced to O(n2) for an object-order algorithm, or to O(log… CONTINUE READING
