2. INTRODUCTION
• 4D opened one new door for imagination and
challenge, creating new types of technology and
design.
• 4D - “the dynamic form resulting from the design of
the behavior of artifacts and people in relation to
each other and their environment”.

3. 4D SPACE
• Mathematically, four-dimensional space ("4D") is
an abstract concept derived by generalizing the
rules of three-dimensional space.
• Algebraically it is generated by applying the rules
of vectors and coordinate geometry to a space
with four dimensions.
• A vector with four elements (a 4-tuple) can be
used to represent a position in four-dimensional
space.

4. 4D SPACE
• A four-dimensional space is simply a space with
four special dimensions, which is a space that
needs four parameters to specify a point in it-
Euclidian space.
• For example, A general point might have
position vector a, equal to.

5. WHAT IS 4D ?
• Scientifically speaking, the 4th dimension is said to
be time. There are 3 special dimensions (x, y, z)
and one temporal dimension-time. In common use
4D generally refers to coordinates in 3D
space/time.
• This dimension is being implemented in various
fields of film making, aerospace, medical,
computing etc.

6. VIEWING IN 4D
• Four-dimensional viewing is the process of
projecting a 4D scene onto a 3D region, which
can then be viewed with regular 3D rendering
methods.
• Viewing parameters for the 4D to 3D projection are
similar to those for 3D to 2D viewing.
• In the 4D viewing model, we need to define the
from-point. This is conceptually the same as the 3D
from-point, except that the 4D from-point resides in
four-space.

7. VIEWING IN 4D
The from-point and the to-point
together define the line of sight for
the 4D scene.
The orientation of the image view
is specified by the up-vector plus
an additional vector called the
over-vector.
Up-vector, over-vector and line of
sight must all be linearly
independent.

8. BASICS OF 4D DESIGN
• 4D designs stresses the relationships of people to
the material forms, and to each other within the
spaces, whether these are pre-mediated by the
professional designer or spontaneously designed
by the users of the spaces.
• It considers- 4D Virtual Design and Dynamic 4D.

9. VIRTUAL DESIGN
• Interactive information points
• Computer games
• On-line shopping
• Interactive television programs
• Computer flight simulations
• Metamorphic internet site design

10. DYNAMIC 4D PRODUCTS
• From the dynamic lighting designs in a
discotheque or office using computer control
technology.
• To the ‘staging’ of Rave concerts.
• From the Fire Alarm that shouts “Fire on the first
floor”.

11. DYNAMIC 4D PRODUCTS
• From the ‘smart’ focusing of a domestic video
camera.
• And automatic doors that open as we approach.
• To solar heat collectors that create imaginative
visual effects on buildings as they follow the path
of the sun across the sky using robotics technology.

12. DISCIPLINES IN 4D
DESIGN
• It depends on the exact nature of the problem.

13. VELOCITY- A NEW
DIMENSION
• For high performance imaging.
• Provides the scientist with an interactive volume
visualization system that will run on a standard
desktop computer.
• Volume interactivity is the key to providing the user
with an enhanced perception of depth and
realism. Interactivity also allows the scientist to
rapidly explore and understand large volumes of
data.

14. VELOCITY
• First true color 4D rendering system designed for
biomedical imaging.
• Uses new highly advanced algorithms to provide
high-speed, easy to use, interactive rendering of
time resolved color 3D volumes.
• Allows the user to visualize a 3D object and then
observe and interact with it over time.

15. VELOCITY ACQUISITION
• Designed for high performance acquisition of
3D sequences.
• Provides easy to use, high speed image
capture capability and is compatible with a
range of scientific grade cameras and
microscopes.
• Acquisition incorporates a unique parallel
processing and video streaming architecture.
This technology is designed to acquire image
sequences direct to hard disk at the maximum
frame rate possible from each supported
camera.

16. VELOCITY ACQUISITION
• Fast and highly interactive volume exploration in 3D and
4D.
• High speed parallel imaging and video streaming
architecture.
• Fly-through rendering for visualizing events inside biological
structures.
• Real time Auto Contrast for fast focusing and acquisition.
• Intuitively easy to use for increased productivity.
• Object classification, measurement and tracking in all
dimensions.
• High quality restoration of confocal and wide field
microscope images.

17. 4D FILM MAKING
• Combining a 3-D film with physical effects in the
theatre, which occur in synchronization with the
film.
• Films include rain, wind, strobe lights, and vibration.
Water sprays and air jets are also common.
• Wind blowing, water spraying, leg and back
ticklers, is usually considered as a 4-D experience.

18. 4D AROMA-SPACE/
SMELL-O-VISION
• Aroma space- Technology that provides platform
for 4D experience.
• Allows people to smell odors and aromas from the
film via scratch and sniff cards.
• Smell-O-Vision, created by Hans Laube, process
injected 30 different smells into a movie theatre’s
seats when triggered by the film’s soundtrack.

19. 4D AROMA-SPACE/
SMELL-O-VISION
• Scratch and sniff is
created through the
process of micro
encapsulation.
• Have been used in films
like “polyester” and
“Spy Kids”.
• The desired smell is
surrounded by micro-
capsules that break
easily when gently
rubbed.

20. 4D ULTRASOUND
SCANNING
The 4D scan displays 4 dimensions
as height, width, depth and
movement of the baby.
4D scan is also referred to as "Live
3D" as the 4th dimension is time
which is the actual movement of the
baby.

21. 4D IN AIRCRAFT
NAVIGATION
• Replaces the concept of Air Traffic Control with
Trajectory Management.
• Allows the controller to send little messages to the
flying plane that will notify what route he’ll be
directed to and at what time should he be at a
certain fix.
• Message can be automatically added to the
plane’s flight management system .

22. 4D IN AIRCRAFT
NAVIGATION
• Allowing on-time scheduling
• Allowing closer aircraft spacing for arrivals
• Allowing continuous descent approaches
• Protection of environment

23. CINEMA 4D- A TOOL
• A 3D modeling, animation and rendering
application developed by MAXON Computer of
Germany.
• Capable of procedural and polygonal/modeling,
animating, lighting, texturing, rendering, and
common features found in 3d modeling
applications.
• Application relies on widely used computer 3D
technology which works by creating groups of
"points" (known as vertices) who form surfaces
when connected.

24. CINEMA 4D- A TOOL
• When a scene is finished it is normally rendered.
Rendering refers to the act of calculating the
scene, the shading, the colors and the textures.
• It then saves the project in many different file
formats including high resolution image and video
files (such as AVI or QuickTime).
• CINEMA 4D has its own programming language,
C.O.F.F.E.E., to develop platform independent
plug-ins.
