1. This form allowing entry of a coordinate location (X, Y, Z) within the model and a coordinate direction (i, j, k). 2. Launch a ray from this location in this direction to find the first intersection with a face 3. Calculate the reflection angle of the ray from the face and launch another ray to find the next intersection 4. For each ray/intersection, create a model line connecting the two points. The end result should be a series of model lines bouncing from item to item. 5. Provide a hard limit of say, 100 intersections, to prevent endless reflections within an enclosed space. 6. Write a log file of the intersection containing: the element type, id, and material of the intersected face.
