3D modeling and animation
- 1. Presented by Muhammad Imran Javed Joura 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
- 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. Website: www.blender.org Blender
