Read full description

A process called Fourier analysis can be used to mathematically break down any image into a number of basic components. By manipulating these components and then reassembling them, a variety of visual effects can be achieved. This process demonstrates how our visual system analyzes images, and how different types of visual problems can affect our perception of shapes and edges. iNSIGHT is a curriculum supplement for experimental psychology, sensation and perception, vision science, and optometry lab classes. There are two different types of iNSIGHT apps: experiments and interactive demonstrations. Experiments are real psychophysical procedures (NOT simulations) that generate real data. Demonstrations illustrate a visual phenomenon and allow students to manipulate the effect. Each lab is complete with a quick-start guide, detailed instructions, background information, and one or more guided exercises. To see how iNSIGHT works, try the FREE iNSIGHT Color Mixing app. A printable PDF Student Guide that contains the exercises and other supporting materials, and a Teacher Guide are available at www.polyhedronlearning.com/see_apps_insight.html

Polyhedron and Polyhedra Volume 2 is a collection of 4 kepler-poinsot polyhedra, 53 uniform star polyhedra, their duals and polyhedral compounds of them. This is also an application which helps you to learn about or explore these mathematical solids. Without knowledge of mathematics or polyhedron, you can easily interact with the 3d solids by this application. So, you will become more familiar with the polyhedrons, and you may enjoy these abstract solids as fascinating formative arts. The main advantage of this app is that it offers a large variety of polyhedral compounds of identical uniform star polyhedra and their duals. By choosing a model, and by setting colors and parameters optionally, you will find various types of 3d shapes including wonderful shapes, mysterious artistic shapes, and strange eccentric shapes, which will be interesting for you. Features: - Swipe or touch gesture will rotate, zoom or move the object. So, you can observe it from various angles or positions. (You can observe it even from inside.) - Switches between showing and hiding each face of the polyhedron, and switches between showing and hiding each component of the compound - Function to display the edges of the polyhedra with selectable thickness and color - For each kepler-poinsot polyhedron, each uniform star polyhedron and each dual of uniform star polyhedron, the app can provide the compound from 14 to 22 kinds (more than 1200 in total). - Many color patterns for the faces of the polyhedron. - Functions to display basic informations about the polyhedron, and to access the wikipedia sites about the related items - Slider controllers to reduce z-fighting (screen flicker) - Save PNG images to camera roll
