4. Technical Presentation

Robin Liu	Title Dependency between Points: Some Observation for Parametric Bezier Patches Abstract I will talk about some observation found in my work on parametric Bezier patches. For two parametric Bezier patches to meet with G^1 continuity, the control points must fulfill certain conditions. In some cases, this condition can never be met. As side control points approach the singular positions, the central control points will go infinity. Also, the two central control points also depend on each other. The detailed dependency will be presented.

Title
Dependency between Points: Some Observation for Parametric Bezier Patches

Abstract
I will talk about some observation found in my work on parametric Bezier patches. For two parametric Bezier patches to meet with G^1 continuity, the control points must fulfill certain conditions. In some cases, this condition can never be met. As side control points approach the singular positions, the central control points will go infinity. Also, the two central control points also depend on each other. The detailed dependency will be presented.
