  1. Chapter 3 The Invisible Surface that Glows

  2. Construction • D. Hoffman suggest that we construct everything that we see • Normal People vs. Mr. S. • Evidence ?? • Subjective contours and surfaces

  3. Borders vs. Brightness • The Illusions below demonstrate constructing a border without distorting the brightness.

  4. Possible Rule • There is a large correlation between symmetry and our ability to construct subjective surfaces. Support Disproof

  5. Rule 11 • Construct subjective figures that occlude only if there are convex cusps.

  6. Parallel Lines • Our mind tends to notice parallel lines and assume them to have some sort of relation.

  7. Rule 12 • If two visual structures have nonaccidental relation, group them and assign them to a common origin.

  8. Rule 13 • If three or more curves intersect at a common point in an image, interpret as them at a common point in space. • This is why the magic square begins to disappear !!

  9. Constructing lines • Rods and Cones • Simple and complex cells focus on the orientation of lines.

  10. 3D Constuction • We are actually able to construct objects. • But this is not limited to illusions printed in this book. We construct everything we see!!

  11. Arguments… • Since we all see the same thing we must not construct it.

  12. Arguments… • If I construct it, why doesn’t it comply with what I want ??

  13. Conclusion • We construct everything we see based on a set of specific rules that allow us all to construct the same objects. • Our visual intelligence is not limited to reality. • Mrs. B
