7. The picture below is an example of a 2D hidden surface removal problem. In this problem, we want to render the portions of the lines that are visible to the viewer Note: For the purposes of this problem consider the eyepoint E as being located at the front of the eye (I.e., where the line representing v starts). a. Suppose we use backface culling to remove some lines segments before drawing the scene. Which lines will be drawn after culling? b. Considering the Painter's Algorithm and the image above, what is the order for polygons to be drawn? (Note: This order is not unique; you just have to give any one order that the Painter's algorithm might produce), 8. Write a javascript function to calculate whether a triangle should be removed by back face culling 7. The picture below is an example of a 2D hidden surface removal problem.
