1. Suppose a tiled plane description looks like:

  tiled_plane floor
  {
     material white
     normal   0 1 0
     point    0 0 0
     dimension 2.0 3.0
     altmaterial green
  }

  For each element of the definition shown below identify the function
  responsible for reading in the element (some answers may be used more
  than once or not at all.

  ___ a. white              1. object_init()

                            2. plane_init()
  ___ b. }
                            3. tplane_init()

  ___ c. normal             4. model_init()


  ___ d. green


2. Components of obj->hitloc are used to determine the color of a tile.
   For a tiled floor the components used are:


   a. x and y                     b. y and z

   c. x and z                     d. x, y and z
