Function: computeThetaBetweenVertices()
computeThetaBetweenVertices(
vtx1,vtx2):number
Defined in: simulation/simulation.ts:1781
computes the angle between two vertices.
Parameters
vtx1
(the last observed vertex - always computes left to right, so this is the leftmost vertex)
vtx2
(the current vertex - always computes left to right, so this is the rightmost vertex)
Returns
number
the theta between the two verticies. -theta means the last vertex is highter (has a higheter y value than the current). +theta means the opposite
