Abstract:
L-system is a rewriting process based on Chomsky grammar that can generate 3D fractals and virtual plants. Its efficiency has been proved for more than twenty years with the works of Lindenmayer and Prusinkiewicz in particular. This paper presents a Real-Time Interactive L-system (RTIL-system) allowing real-time rendering, interactions with a user and/or the environment, haptic feedback and covering most of the important L-systems extensions such as parametric and context sensitive features. Different potentialities of the RTIL-system are illustrated where the user intervention becomes an essential element of plant/fractal evolution through Virtual Reality and Augmented Reality applications.
