3D lenticular picture depth design

Certainly the most striking effect of a 3D lenticular picture is its ability to display depth. Consequently, the 3D lenticlar artist is under pressure to maximize this effect by displaying scenes with larger depth. Practice has shown that uncontrolled depth increase leads to a failure. This gives rise to the question: is there a limit to the depth which can be displayed in a 3D lenticular picture? The answer to this question is: Yes! The theoretical limit is illustrated and e

The making of a lenticular picture

A lenticular picture is made from two components: a print and a lenticular sheet. These components have to be bonded together with a very high precision. The print is composed from thin stripes arranged in cells. In the picture below each stripe is numbered and painted in a different color. A cell is a group of adjacent stripes which fills the space spanned by a single lenticule. In the picture below there are five stripes in a cell, but in real lenticular pictures this numbe

Fractal art

"Fractal art is a form of algorithmic art created by calculating fractal objects and representing the calculation results as still images, animations, and media." Wikipedia The aesthetic beauty and diversity of fractal shapes inspired numerous artisis who created a new genre in art: Fractal Art. As the original fractal shapes were two-dimensional, so where the first fractal works of art. Presently there are several programs which are used for creation of artistic 2D fractal p

Fractals

Fractal patterns (or, in short, "fractals") emerged in the 17th century in mathematics. They are characterized by displaying repeating patterns on every scale. In the 1960s the mathematician Benoit Mandelbrot published a curious mathematical set, which became widely known as the "Mandelbrot set". This set is defined by a very simple mathmetical formula, but its boundaries display self-similar patterns on every scale. The striking properties and appearance of the Mandelbrot se

The software

To make virtual sculptures one needs a software for digital 3D modeling. Digital 3D modeling has important applications in many disciplines, including engineering, design, advertisement and the movie industry. As a result, there are nowadays many software products which can be used for virtual sculpture. Notable examples are 3D Studio Max, Maya and Zbrush; a comprehensive list can be found in Wikipedia. Some of the software products focus on creation of 3D bodies, and other o

Display of virtual sculptures

When you view a picture on a computer monitor you see tha same picture in both eyes. When you view a 3D lenticular picture, each eye sees a different perspective of the displayed object. This difference in views simulates a special mechanism in your brain called "Stereopsys", which creates the 3D sensation. Certainly there is no way to create 3D sensation with a computer monitor without any visual aids. The best one can do is to present an animation in which the object is sho

Virtual sculpture: a new art of the digital era

"Sculpture is the branch of the visual arts that operates in three dimensions" Wikipedia, July 2014 Until the digital era, sculptures had to be created using real matter. The advent of digital tools gave rise to a new art: virtual sculptures. A virtual sculpture is a digital file and has no material presence. Such sculpture cannot be touched, nor be placed on a table or erected in a town square. It can be, however, (virtually) photographed, and one can have the picture printe
