Title: Better Pasting Through Quasi-interpolation
Abstract:
Hierarchical surface pasting is a method for adding detail to a smooth surface without increasing the complexity of the base surface. The detail is added by placing tensor product B-spline surfaces on top of the base surface. The method by which the detail surfaces are constructed is fairly fast, but it produces details whose boundaries are less-than-perfect approximations of the base surface. Thus, the composite surface often contains gaps between the base and detail surfaces. We will describe a technique called "quasiinterpolation" which may be used to approximate functions. We will then outline how this technique may be applied to surface pasting to produce higher quality surfaces without negatively impacting on the cost of the pasting procedure.

Who:   Viet-Tam Luu
Where: DC1304
When:  Thu March 26, 4:30-5:30pm

What:
  OpenGL is a graphics  library, or rather a "software interface to graphics
  hardware" that  allows one to  easily write programs  with high-performance,
  interactive three-dimensional  graphics.   This  talk will  provide a  brief
  introduction to OpenGL: a  summary of its features and  capabilities, and an
  overview of the concepts and techniques used in programming with OpenGL.

What:
  The Loose Nut That Holds The Keyboard:

  The Effect of the Failures of Subtlety and the Violation of the Laws of
  Stussy, Freud and William of Occam on software use.

  If I were to chase you with a meat cleaver, it is unlikely you would pay
  any attention to a performance of Aida, even if the cast were stark
  naked.  All of us have had experiences where the emotional state
  controlled the logical response.

  Are software systems any different from meat cleavers?  Nope!  The same
  organization of priorities affects how a person reacts to a software
  system.  The lack of recognition of the "emotional human" by designers
  and scientists limits the effectiveness of their efforts.
