Calculation

• Calculation is a function to join & rejoin objects to a contin, and record their geometric properties

• Contin in Elegance is a group of objects which connect together and form a neuron cell.

Before Calculation

After Calculation

Calculation Algorithm

• Pick up one object • Find its connectivity partners • If # partners <> 2, then its type is ‘Branch Point’,

mark in red. When Branch Point found, branch number ++

• Continue to find its partner’ partner, until no more object connected.

Calculating Synapse

• Given a contin number, find out all the presynapses from it, all the postsynapses to it, and their position (which branch? which section?)
