“…3Gmap L-systems are a boundary representation model that can control the shape and structure of 3D objects, using high-level operations on volumes. Terraz et al [30] introduced this concept to model wood by growth simulation. Peyrat et al [23] present parametric grammars, an extension that uses variables and mathematical functions to model realistic leaves with 2Gmap L-systems.…”

Modeling a fruit using classic 3D modeling software can be a relatively complicated task. Moreover, modeling every single fruit when we need to generate a large variety of fruits of the same species is not a viable option because it is time consuming. This paper presents an original ad hoc method for modeling a wide range of 3D fruits, using a single formal grammar. Fruits are modeled by parametric 3Gmap L-systems that describe their shape and internal structure, thanks to variables and mathematical functions. At the end of our work, our method will eventually be an interesting solution to realistic modeling of fruits and their interior, and to automatic detection and recognition of real fruits.

“…Another approach is to progressively simulate the growth of the tree over time. Examples include voxel-based approaches [Buchanan 1998], level-set methods [Sellier et al 2011], and L-systems [Terraz et al 2009]. Since these methods have greater access to global information, they are able to model large-scale topological features such as branches and knots as shown in Figure 4 .…”

Figure 1: A guitar model featuring a couple different wood materials: quilted maple on the body and walnut on the neck. The image is rendered using our comprehensive, volumetric, procedural model of wood. We simulate most of the significant wood features: growth rings, pores, rays, and growth distortions. Furthermore, our model can produce the anisotropic specular highlight arising from reflection from the subsurface fiber structure, as seen in the quilted maple figure. The fiber directions are automatically derived from the growth distortions. Model by Nikos Natsios. Inset: A photograph of real quilted maple.

“…Prusinkiewicz and Lindenmayer in [Prusinkiewicz and Lindenmayer 1996] proposed many methods based on L-systems. In [Terraz et al 2009] an extension of L-systems is proposed, based on three-dimensional (3D) generalized maps that allow an easier control of the internal structure of 3D objects.…”

This paper presents biologically-motivated a procedural method for the simulation of leaf contour growth and venation development. We use a mathematical model for simulating the growth of a plant leaf. Leaf tissue is regarded as a viscous, incompressible fluid whose 2D expansion is determined by a spatially varying growth rate. Visually realistic development is described by a growth function RERG that reacts to hormone (auxin) sources embedded in the leaf blade. The shape of the leaf is determined by a set of feature points within the leaf contour. The contour is extracted from photos by utilizing a Curvature Scale Space (CSS) Corner Detection Algorithm. Auxin transport is described by an initial auxin flux from an auxin source to an auxin sink that is gradually channelized into cells with high levels of highly polarized transporters. The leaf is presented as a triangulated double layer structure that consists of a Voronoi-Diagram that is discretised along the vein structures.
