1 FixtureNet II: Interactive Redesign and Force Visualization on the Web Charles Anderson Yan Zhuang Ken Goldberg UC Berkeley

2 Background Modular Fixturing Brost-Goldberg Algorithm –complete fixture synthesis FixtureNet I –CGI-based (1994)

3 Objectives New, Java-Based User Interface on top of existing FixtureNet server program Interactive Force Display Interactive Part Redesign Build Better Intuition about Parts and Fixtures

4 FixtureNet Processes

5 Interactive Force Display Compute Fixel-Edge Contacts Display Unit Reaction Forces

6 Interactive Force Display User Force Input –Mouse click & drag  force origin, magnitude & direction –solve for reaction forces: four 3x3 systems of equations –update display

7 Interactive Redesign Reuse 3 locators ignore clamp Edges w/o locator are unrestricted Fix 2 edges and move third Complex shape

8 Control Curve Move locators along edges 3rd point sweeps elliptic curve - the control curve 3rd edge must intersect CC

9 Different Parts - One Fixture

10 Conclusions New User Interface Force Display Part Redesign Better Intuition
