Sidewalks are not a trivial topic. They fundamental element of streets, the main public spaces in urban environments. In modern cities, paving materials mostly artificial. Portugal, stone-paved sidewalks still prevalent and quite characteristic. Walking down street, you do need to lift your eyes off ground know Portugal. nineteenth-century Lisbon, new type pavement was introduced, calçada portu...

This paper presents DrawCompileEvolve, a web-based drawing tool which allows users to draw simple primitive shapes, group them together or define patterns in their groupings (e.g. symmetry, repetition). The user’s vector drawing is then compiled into an indirectly encoded genetic representation, which can be evolved interactively, allowing the user to change the image’s colors, patterns and ult...

In composing hand-drawn images of 3D scenes, artists often alter the projection for each object in the scene independently, thereby generating multiprojection images. We present a tool for creating such multiprojection images and animations, consisting of two parts: a multiprojection rendering algorithm and an interactive interface for attaching local cameras to the scene geometry. We describe ...

We introduce a novel intelligent system which can generate new Chinese calligraphic artwork that meets certain aesthetic requirements automatically. In the machine learning phase, parametric representations of the existent calligraphic artwork are derived from input images of calligraphy. Using a six-layer hierarchical representation, the acquired knowledge is organized as a small structural st...

We describe a flexible algorithm that can create many different kinds of aesthetic fractal patterns. The main idea of the algorithm is to randomly place progressively smaller copies of a motif within a region, thus producing a fractal pattern. This has been found to work for a wide variety of shapes for both the motif and the enclosing region. We show a several examples. If the region is a fund...

This short note describes a development of the traditional Pythagorean tree fractal to produce interesting three-dimensional structures based on cubes rather than squares. Adding a 90˚rotation at each bifurcation encourages three-dimensional growth, creating increasingly artistic shapes as the branching angle decreases. 1. Pythagorean box trees The Pythagorean tree is a plane fractal constructe...

the industrial design is a two or three-dimensional aesthetic creation related to industrial products. according to the definition of the iranian law, for the realization of the legal protection of industrial designs there are three necessary components: combine lines or colors, runs on industrial products and change product appearance. in iran, only the registered designs are supported. while ...
