A small L-System (Lindenmayer System) interpreter written in Java.
LINN ({L}-System interpreter developed in {INN}sbruck) is a small, configurable L-System interpreter with the following features and design intentions:
- Types of L-Systems supported:
- Both context-free and context-sensitive ones
- Both stochastic and deterministic ones
- Parameterized ones
- Written in Java 8 and offering
- a fluent API for specifying and executing L-systems
- an optional ANTLR4 grammar (for external, textual specification)
- Core library has no noteworthy external dependencies (just Google Guava)
- Core library does not include any render capabilities (although examples do)
- User code injection to accomplish the following:
- Condition evaluation for selecting production rules
- Parameter values, default values and variables
- Notification actions on productions and entire interations (e.g. useful for rendering, logging of results, etc.)
- Syntax mostly based on what can be found in Prusinkiewicz, Lindenmayer, Hanan, et al., "The Algorithmic Beauty of Plants", freely available here
- Examples will show both API usage, actual rendering in Processing/OpenGL and export of production results as meshes/point clouds
Project status: 50%
What works so far:
- Fluent API for defining L-systems and executing them
- State change and post execution notifications to trigger e.g. rendering
- Deterministic, context-free L-systems
- Stochastic L-systems
- Basic examples (2D) rendered as Processing sketches
Current milestone: further productions, parameterized rules, examples
That's it for now :)
