- How to highlight nodes? Draw a ring as in cgoban? |
50 |
|
Change the color and interpolate to the middle of the connection? |
51 |
|
Should the connector between two highlighted nodes become |
52 |
|
highlighted? |

|
- Is a static graph (compiled in a displaylist) enough? |
54 |
|
It can still be rotated. |

- thought about surface tension and 3D area--volume optimization |
58 |
|
- Mean curvature multiplied by surface tension is proportional |
59 |
|
to the pressure difference (Laplace-Young equation). |
60 |
|
- Pareto-optimal points of area--volume optimization problems |
61 |
|
have constant mean curvature, which is analogous to the |
62 |
|
constant curvature solutions of the 2D length--area optimization. |
63 |
|
- The only constant curvature surfaces of revolution are |
64 |
|
catenoid (roulette of a parabola), unduloid (roulette of an ellipse), |
65 |
|
and nodoid (roulette of a hyperbola, not embedded). |
66 |
|
Plane, cylinder, and sphere are special cases of the above. |
67 |
|
- The shape of a droplet is the result of downward linearly increasing |
68 |
|
mean curvature (as the pressure builds up). |
69 |
|
- The mean curvature of the (stretched)circuloidal fillet jumps |
70 |
|
down as it leaves the spherical node (mean curvature 1/radius) |
71 |
|
and then increases to the maximum (approx. 0.5/thickness) at the |
72 |
|
middle of the connection. |
