  1. IAT-241AnimationVisualization Visual thinking  Hand and digital drawing 3D spaces and transformations

  2. Visual Thinking • Mental process through images not words • Learning to look first • Process is as important as the result • Visualization as a means of: • Extending the thoughts • Communicating the thoughts

  3. Drawing • Skills to exercise • Improvise • Add details to basic shapes to create new • Recycle • Copy scenes using quick strokes (basic shapes) • Explore • Find objects in random lines • Express • Add details to a basic head to create characters

  4. Improvise

  5. Recycle

  6. Explore

  7. Express

  8. Visual Language • Creative Clichés • Deep Structure • Less is more! • Graphic Styling • Line and body language • Background • Color psychology

  9. Some Visual Cues • Heavier lines come forward • Foot placement indicate ground • Use more details in foreground • Employ perspective lines • Place shadows • Place horizon line high in the frame

  10. Going Digital • Digital Images • Bitmap • Vector • 3D • Paint/Draw programs • Input devices • Some things never change!

  11. 3D Spaces • Dimensions • Coordinate systems • Cartesian • Spherical or azimuthal • World/global vs. object/local • Numbers • Integer vs. floating point • Decimal vs. hexadecimal

  12. Basic Shapes • Point • Line (straight and curve) • Spline • Linear, cardinal, b-spline, Bezier, and NURBS (Non-Uniform Rational B-Spline) • Surface • Edge and vertex • Orientation and surface normal • polygons

  13. Splines

  14. Geometric Primitives • Cubes and Spheres • Cylinders and Cones • Toruses • Polyhedra • 2D shapes and sweeping • Extrusion • Free-form sweeping • Lathe

  15. 3D Transformations • Transformation matrix • Translation • Rotation • Scaling • Perspective projection • Camera navigation

  16. File Formats • Image • BMP, JPG, GIF, TGA, TIFF • Structured image • PhotoShop, Corel, etc • Movie • AVI, MPEG, Real, QuickTime • Modeling • DXF, 3DS, VRML, etc
