New Ray Tracing Method to Investigate the Various Effects on Wave Propagation in Medical Scenario: An Application of Wireless Body Area Network

Algorithm 1

Minimization_of_Ray_Object_Intersection().

(1) For each ray do

(2) {

(3)  Retrieve the information of previous intersected object

(4)  Perform the intersection test between the ray and previous intersected surface

(5)  If intersection is not exist then

(6)  {

(7)    For each object in a tree do

(8)   {

(9)    Extract two surfaces from each object

(10)      Perform intersection test with the first candidate surface

(11)    If intersection is found then

(12)   {

(13)    Store the information of the intersected object

(14)    Stop searching

(15)     }

(16)     Else

(17)     {

(18)    Perform the intersection test with the next candidate surface of the same object

(19)     If intersection is found then
