Interactive tree growth model with environment sensitivity

I designed this model based on the DBM model which simulates the propagation of a lightning discharge. In this model I used Honda model to generate the binary tree geometry and random growth of branches was modeled using Monte-Carlo method where it was possible to simulate the biasing of branches with the resource availability. First version of this algorithm was presented in SIGGRAPH Asia 2012 posters

For my Mphil research I combined binary tree growth algorithm with DBM and created a new growth model which simulates the growth of a tree with environment interactions which allows a tree to adapt to the distribution of light and proximity to solid obstacles it its growth cycle. This program generates POV-Ray file for each step of the tree growth so by rendering the generated POV file sequence, tree growth can be modeled step by step

• conf\initialize-params.cfg -this file has all the parameters you can control with the program. You can define the grid size (environment), Light Source configurations, Obstacle configurations, basic branch properties etc…
• Run the Release\laplace_3d_sth_3_rand.exe
• file will generate in the output folder with the addition of each branch to the tree.

I know this program is too buggy and need so much developments. But as a prototype it works great for my research scope and gives considerably good results. I really appreciate your comments and feedback for further improvements of this project.

Have a nice time!
