`generate_tree.Rd`

Generates a procedural tree with

generate_tree( x = 0, y = NULL, z = NULL, seed = 2000, midpoint = TRUE, branch_depth = 6, branch_scale = c(0.8, 0.9), branch_angle = c(-30, 30), branch_angle_vert = seq(-45, 45, by = 5), branch_split = 2, branch_prune_prob = 0, branch_color = "#603000", branch_radius_shrink = 15, leaf_color = "green", leaf_depth_start = NULL, leaf_size = 0.2, leaf_prob = 1, scale = 1 )

x | Default `0`. Either the x-coordinate, or if a length-3 vector the x,y, and z coordinates of the base of the tree. |
---|---|

y | Default `NULL`. The y-coordinate of the base of the tree. Ignored if the `x` is a length-3 vector. |

z | Default `NULL`. The z-coordinate of the base of the tree. Ignored if the `x` is a length-3 vector. |

seed | Default `2`. Random seed for generating the tree. |

midpoint | Default `TRUE`. Method of extending branches. If `FALSE`, it grows directly to the next node. Else, it first extends a midpoint given the previous orientation and grows from there to the end point. |

branch_depth | Default `6`. Number of branch splits to end tree. |

branch_scale | Default `c(0.8,0.9)`. |

branch_angle | Default `c(-30, 30)`. Horizontal branching angle from previous branch. |

branch_angle_vert | Default `seq(-45,45, by=5)`. Vertical branching angle from previous branch. |

branch_split | Default `2`. |

branch_prune_prob | Default `0`. |

branch_color | Default `#603000`. |

branch_radius_shrink | Default `15`. Constant that determines the rate the radius shrinks. Higher values result in less shrinking. |

leaf_color | Default `NULL`. |

leaf_depth_start | Default `NULL`, automatically set |

leaf_size | Default `0.01`. |

leaf_prob | Default `1`. |

scale | Default `1`. Uniformly scale the tree. |
