The document explains the concept of 3D images, including how they are perceived by the human eye and the mechanics behind 3D glasses. It describes the differences between 2D and 3D images and outlines a simple method to create homemade 3D glasses using cardboard and colored cellophane. Additionally, it discusses the process of making 3D images by combining stereopair images with color filters.

1. What is 3D? Bethany Smith NC State University

2. Is this 3-D?

3. What about this one?

4. Is this one 3-D?

5. What makes an image 3-D?

6. What does 3-D stand for?

7. How many dimensions were the previous illustrations?

8. What makes an object 3-D?

9. 2-D X Y

10. 3-D X Y Z

11. How do 3-D Images work?

12. How does depth work? Using your eyes to combine the two images they see

13. 3-D images can only work when each eye sees a slightly altered image

14. How do we get our eyes to see different images?

15. How do the glasses work? Separate the images by filtering Filter by color Red Blue

16. Making your own 3-D glasses Supply list Cardboard for glasses Red and Blue cellophane Scissors Tape

17. How do the images work? Two images One for the left eye - red One for the right eye - blue Exactly the same as the glasses!!! The blue side makes the blue disappear - so all you see is the red image in your right eye and Vice Versa

18. How 3-D images are Made

19. Take 1 Stereopair

20. Color the left red and the right blue

21. Combine the two together
