Fractal Tree 5.16.2024
Description
Fractal Tree 5.16.2024 10 various fractal tree .stl files are provided or you can create your own using BlockCad or OpenSCAD. Note that the versions with N_max = 10 can take a while to print. The version with N_max = 4 prints the fastest. The included BlocksCad (.xml) and OpenScad (.scad) files are much more compact than my previous attempt since they use recursive programming. Tree leaning option is now included. BlockCad is a free program to use on-line: https://www.blockscad3d.com/ OpenSCAD is a free download at: https://openscad.org/ Tabulation of recursive tree models in this post variables common to all models: variable T_extrude L_ratio L1 T1 value 1.2 0.8 30 8 variables that may change with each model model Th_turn TH_lean N_max T_ratio fractal_tree_recursive_3_240514_1 48 0 10 0.75 fractal_tree_recursive_3_240514_1a 48 7 10 0.75 fractal_tree_recursive_3_240514_1b 48 14 10 0.75 fractal_tree_recursive_3_240514_2 48 0 6 0.75 fractal_tree_recursive_3_240514_2a 48 7 6 0.75 fractal_tree_recursive_3_240514_3a 65 0 10 0.75 fractal_tree_recursive_3_240514_4 48 0 8 0.75 fractal_tree_recursive_3_240514_5 48 0 4 0.75 fractal_tree_recursive_3_240514_6 48 0 12 0.75 fractal_tree_recursive_3_240514_7 48 0 10 0.65 The following variables are used in the program to change the tree: distances are in mm all angle are in degrees TH_turn is the angle between new branches --- this controls how wide the tree is TH_lean is the angle that next branches lean left or right --- looks like the tree is swaying in the wind L_ratio is the ratio of the length of the next branch compared to the current branch T_ratio is the ratio of thickness of the next branch compared to the thickness of the current branch L1 is the length of the trunk (branch 1) T1 is the thickness of the trunk (branch 1) N_max is the number of branches outward, the trunk is branch 1
