Vectors and bending

  1. Jul 2, 2008 #1
    1. The problem statement, all variables and given/known data

    How is it possible to find the modified growth direction of a tree branch? And after this new vector is computed how should the next one be computed (the next segment growing from the last position)?

    The objective of all this is to program and produce a tree which is severely affected by wind (using L-systems).

    2. Relevant equations

    e = susceptibility to bending *** value something like 0.4***
    wind = a vector (x,y,z)
    heading = a vector(x,y,z) ***initial state = 0,0,1***

    3. The attempt at a solution

    First vector is (as below?)

    Corrected Vector = e *multiplied* by cross product of (Wind and Heading vector)

    Second Vector = e *multiplied* by cross product (Wind and Corrected vector)

    Im pretty sure that second vector is wrong...
