• GUI
  • input modes: request, sample, event
  • input devices: locator, stroke, valuator, choice, pick
  • constraints, grids, gravity, rubber-band, dragging, rubber stamp
• structured graphical items
• visualization: pseudo-color, contour, volume rendering, vector fields, fluid flows (streamers, particles), multivariate data fields
• parametric forms: for lines, for objects, for surfaces
• curves: splines, Bezier, forcing curves by points, surface
  drawing curves:
  • Continuity ( 0 meets, 1 tangents equal, 2 second derivative equal),
  • poly-line formula (use a lot of points),
  • parametric equations,
  • spline curves (natural spline (all points included in formula), Hermite (two points and slopes at points), Cardinal (two points and information from point before and after), Kochanek Bartels (add tension, bias) ),
  • Bezier curves (constrained by convex hull, goes near points except first and last)
• 3D planes: right hand rule, face normal, parametric form
• 3D surfaces: ruled surfaces (cone, cylinder), quadric, patches
• 3D solids: points, math, sweep, parametric, Bezier surface, CSG, octrees, blobby objects, extrusion/deformation/morphing, fractals
