Surface and Cell Contact
By controlling a cell’s surface, you can adjust the amount of perimeter it exposes to neighbors or the Medium. We recommend to always add the Contact plugin when creating a new simulation.
Properties
cell.targetSurface: the “goal” surface that a cell tries to reshape itself to whenever possible.
For roughly square or blob-shaped cells, targetSurface would be 4*sqrt(targetVolume).
cell.lambdaSurface: the strength of the surface constraint; that is, how quickly a cell will reshape itself to meet its targetSurface.
