LSystem
The L-System (Lindenmayer System) generator allows you to create complex procedural structures like trees, bushes, and other organic shapes using a set of rules and parameters.
Parameters
- Axiom: The initial state string (the seed) of the L-System.
- Rules: A list of production rules that define how symbols are replaced in each iteration.
- Predecessor: The character to replace.
- Successor: The string to replace the predecessor with.
- Angle: The angle in degrees for rotation commands.
- Length: The length of the segments drawn by the turtle.
- Width: The initial width of the segments.
- Width increment: The amount to increment or decrement the width when using width commands.
- Iterations: The number of times the rules are applied to the axiom. Higher values create more complex structures but take longer to generate.
- Leaves radius: The radius of the leaves generated by the 'L' command.
Commands
The L-System uses a "turtle" graphics approach where a cursor moves through 3D space following these commands:
| Command | Description |
|---|---|
F |
Draw line forwards |
( |
Set voxel type |
b |
Move backwards (no drawing) |
L |
Generate a leaf |
+ |
Rotate right |
- |
Rotate left |
> |
Rotate forward |
< |
Rotate back |
# |
Increment width |
! |
Decrement width |
[ |
Push state (save position and rotation) |
] |
Pop state (restore position and rotation) |
Templates
VoxEdit comes with several built-in templates to get you started:
- Simple Tree: A basic tree structure that branches in 4 directions.
- Dense Bush: Short, wide, and bushy with many leaves.
Usage
- Select a Template: Start by selecting a template from the dropdown menu to see how it works.
- Modify Parameters: Adjust the angle, length, and iterations to change the shape and size of the generated structure.
- Edit Rules: Add or modify rules to create custom branching patterns.
- Adopt Dimensions: Use the "Adopt Dimensions" button to automatically adjust the length and width parameters based on the current selection or volume size.
- Generate: Click "OK" to generate the voxel structure at the reference position.
Tip: Use the
[and]commands to create branching structures.[saves the current position and direction, allowing you to draw a branch, and]restores the saved state to continue from the branching point.
