This document provides an overview of 3D modeling and animation. It discusses key concepts such as dimensions, 3D modeling representations including polygonal and curve modeling, texturing and assigning materials, rigging and constraints for animation, and simulations. Methods for animating scenes like tangled lanterns and battle scenes are presented. The document also covers rendering 3D models which can take significant computing resources. Important features for 3D modeling tools are outlined.

3-D Modeling and Animation
Main topic:

2. A dimension is a physical quantity that gives us
information about the state of a system.
A system is n-dimensional if there are n physical
quantities which completely define the state of the
system.
Dimension

3. What is 1D
 A line just have Length

4. What is 2D
 Plane having width and
height

5. What is 3D
 having width, height
and depth

7. Projection

8. • Binocular vision
• Monocular(parallax)
• Colors and shadows
• Experience
How do we perceive depth ?

9. 3D movies

10. Parallax scrolling.

11. Perspective vs Orthogonal view.

12. • 360 degree video
• Sphere
• Surface of sphere.
Are these 3D

14. • The process of developing a mathematical representation of
any three-dimensional surface of an object.
• The product is called a 3D model
3D modeling.

15. • Abstract
• Using a formula.
• Solid
• Define the volume
• More realistic
• Difficult to build.
• Used in simulations
• Surface
• Define the boundary
• Easier to work with.
3D models Representations

16. • Polygonal modeling.
• Using polygons
• Quick rendering.
• planar
• Approximate curved surfaces
• Curve modeling.
• Surfaces are defined by curves
• Digital Sculpturing.
Ways of modeling.

17. •Abstract representation and simulations
•Particles
•volumetric materials
How to represent smoke and fire?

18. • A material defines the optical properties of an object: of
what material object is made of. its color and whether it is
dull or shiny.
• A texture is a pattern that breaks up the uniform
appearance of the material.
• textures have to be attached to materials to affect objects.
• Bump mapping.
• simulating bumps and wrinkles on the surface of an object.
Texturing and material assigning

19. • Skeletal animation
• represented in two parts:
• a surface
• a hierarchical set of interconnected bones (called the skeleton or rig)
• humans or more generally for organic modeling,
Rigging and constraints

20. • making the illusion of motion by rapid displaying of
slightly different images
Animation.

21. • Cloth simulations
• Physics simulation
• Adding force fields.
• Fluid simulations.
Simulations.

22. Tangled lantern Scene.
Tangled is Disney’s 50th anim movie. Released in 2010
And over 45,000 lanterns were used during the "I See the
Light" sequence.

24. Tangled lantern Scene.
How animators animate these lanterns?

25. Lord of the ring Battel Scene.
1st movie which used a crowd simulator named
“MASSIVE”
Used artificial intelligence,
Some actions and sensors were defined
Physics was definitely considered.

26. • Rendering is when the computer finally uses intricate algorithms
to apply the effects you have specified on the objects you have
created
Rendering

27. • Rendering an image requires great computing muscle and often
takes many hours for a single image
• some multimedia and animation companies dedicate certain
computers solely for rendering.
• The final images for the classic animated movie “Toy Story” were
rendered on a “farm” of 87 dual processor and 30 quad-
processor 100 MHz SPARCstation 20s. It took 46 days of
continuous processing to render that film’s 110,000 frames at a
rate of about one frame every one to three hours.
Rendering

28. An artist trying to guess perspective

29. Advantage of 3D technology
• Flexibility, ability to change angles or animate images
• Ease of rendering, automatic calculation and rendering
photorealistic effects rather than mentally visualizing or
estimating
• Accurate photorealism, less chance of human error in
misplacing, overdoing, or forgetting to include a visual effect.

30. A good 3-D modeling tool should include
the following features:
• Multiple windows that allow you to view your model in each
dimension, from the camera’s perspective, and in a rendered
preview
• The ability to drag and drop primitive shapes into a scene
• The ability to create and sculpt organic objects from scratch
• Lathe and extrude features

31. A good 3-D modeling tool should include
the following features:
• Color and texture mapping
• The ability to add realistic effects such as transparency,
shadowing, and fog
• The ability to add spot, local, and global lights, to place
them anywhere, and manipulate them for special lighting
effects
• Unlimited cameras with focal length control
• The ability to draw spline-based paths for animation

32. Free, Open Source, cross platform
We can create animated films, visual effects, art,
3D printed models, interactive 3D applications and video games.
