Panel Simulation with Custom Joints

Here’s a quick test of simulating the joints between rigid panels.

Instructions:

  • Hold right MB and drag to rotate the view
  • Zoom with mousewheel
  • Left Ctrl + Left MB on a panel or joint and it will become a moveable handle (object will turn yellow). Repeat to disable.
  • Left Shift + Left MB on a panel or joint and it will become a positional restraint (object will turn red). Repeat to disable.
  • Add a uniform force upwards using the buttons on the top left of the screen
  • Adjust the force necessary to break the joints with the scrollbar

Gaspard Monge Curvature Line Vault

While principal curvature lines seem to be currently very popular, they’ve been around in architecture since 1796.

Gaspard Monge, a french geometer, proposed the above design for an ellipsoidal vault that could be constructed out of mortarless masonry units. Not only did he come up with a completely new way to build such vaults, he actually solved a much bigger problem: how to construct freeform surfaces out of discrete units (see [1], [2], and [3]).

One major characteristic of the patterns that the principal curvature lines of a surface create is that while they are stable for small disturbances of the surface, larger disturbances will cause the overall pattern to “jump” to a new one. This kind of behaviour is called a bifurcation. Now, designing something that wants to bifurcate every time it is modified is fairly difficult. Maybe an understanding of what kinds of surfaces have the same principal curvature line pattern would make this easier? Limiting the design to such surfaces would embed the rationality of the curvature line pattern directly into the design process.

Principal Curvature Lines

Here’s a quick video of the component in action. There’s still a lot of work to be done.

SPM Custom GH Components

The Studio for Progressive Modelling (SPM) has  started development of a couple custom GH components:

This one produces a principal curvature line emanating from a point on a surface – lines that are useful for constructing panelizations of freeform surfaces consisting entirely of planar quadrilaterals and prismatic structural members. It has been proven that surfaces with these characteristics are significantly more cost effective. However, the aesthetics of these panelization schemes are often quite pronouced, and so this component is a light weight solution that allows designers to see what kind of principal curvature mesh a given surface might suggest.

See Evolute  and Daniel Piker’s work in this area for other aspects of panelization with planar elements. I find the latter approach very interesting, as it does not depend on a setting out the curvature lines as an initial guess – even though these are fundamental to the construction. Or are they?

We’re also working on some Rhino to Revit/SAP links, and hope to post some information on those soon.
