1. The diagram below shows a scene where the numbered darker lines are polygons, and the arrows show the orientation of the polygon. Below that is a BSP tree constructed from this scene. 4 Suppose we want to render polygons back to front for painter's algorithm using this BSP tree. For each of cameras 1,2,3 and 4, give the rendering order of the polygons a. 1) 2) 3) b. Suppose polygon B is rotated 90 degrees clockwise. What is a new BSP tree starting with B as the root node (if you have to choose a polygon as part of the tree building algorithm, choose in the order of A,B,C and D). 1.
