1. 1. Dimension John Jason Magic Voldemort
2. 2. • Part 1: Deﬁnition of dimension• Part 2: One dimension• Part 3: Two dimension• Part 4: Three dimension• Part 5: Four dimension
3. 3. Part 1: Deﬁnition of dimension
4. 4. Deﬁnition of dimension
5. 5. Deﬁnition of dimension•The dimension of a space or object is informally deﬁned as the minimum number of coordinates needed to specify each point within it.
6. 6. Part 2: Onedimension
7. 7. One dimension
8. 8. One dimension•One dimension is actually referring to a line.•it can also be interpreted as the point of moving into the line.•it also refers to objects which has no area and volume.
9. 9. Part 3: Twodimension
10. 10. Two dimension
11. 11. Two dimension•To say that a surface is "two- dimensional" means that, about each point, there is a coordinate patch on which a two-dimensional coordinate system is deﬁned.
12. 12. Part 4: Three dimension
13. 13. Three dimension
14. 14. Three dimension•The three dimensions are commonly called length, width, and depth (or height), although any three directions can be chosen, provided that they do not lie in the same plane.
15. 15. 3D in real life
16. 16. 3D in real life
17. 17. 3D in real life
18. 18. 3D in real life
19. 19. 3D computer graphics
20. 20. 3D computer graphics
21. 21. 3D computer graphics•graphics that use a three- dimensional representation of geometric data (oftenCartesian)
22. 22. Pyramid
23. 23. Khufu Pyramid
24. 24. Khufu Pyramid• As a miracle of artiﬁcial construction in the world, the ﬁrst pyramid of Khufu is the worlds largest pyramid, built during the beginning of Khufu pyramid height of 146.59 meters slope length is 186.2967 meters.It is featured with the bottom edge length of 230.2628 meters, more than 250 million units, each weighing about 2.5- - 50 tons of stone.
25. 25. Khufu Pyramid• As a miracle of artiﬁcial construction in the world, the ﬁrst pyramid of Khufu is the worlds largest pyramid, built during the beginning of Khufu pyramid height of 146.59 meters slope length is 186.2967 meters.It is featured with the bottom edge length of 230.2628 meters, more than 250 million units, each weighing about 2.5- - 50 tons of stone.
26. 26. The number of"coincidences"
27. 27. The number of "coincidences"• The perimeter of the bottom of the pyramid of Khufu, if divided by the height of the double get manufacturers to 3.14159, which is pi.
28. 28. The number of "coincidences"• The perimeter of the bottom of the pyramid of Khufu, if divided by the height of the double get manufacturers to 3.14159, which is pi.
29. 29. The number of"coincidences"
30. 30. The number of "coincidences"• It is nothing to do with coincidence that the Khufu pyramid Meridian just divide the Earths land and sea into equal areas.
31. 31. The number of "coincidences"• It is nothing to do with coincidence that the Khufu pyramid Meridian just divide the Earths land and sea into equal areas.
32. 32. Golden Ratio
33. 33. Golden Ratio•If the half of bottom edge divide the pyramid slope length (hypotenuse distance), there will be 0.618.
34. 34. • If you have a right-angle edge,
35. 35. • If you have a right-angle edge,• And you have a stick and a rope,
36. 36. • If you have a right-angle edge,• And you have a stick and a rope,• How do you determine the other edge of the right angle?
37. 37. Part 5: Fourdimension
38. 38. Thanks for watching• All information is citied from Internet.
