PRISM is a fun and magical exploration of real light shining through glass prisms and splitting into natural rainbows beneath your fingers. Interact with a variety of beautiful scenes, or create your own. Completely accurate in math and physics, you will be amazed at the visual explosion from just a few simple prisms.
* Featured in the Future Canvas 2 iPad art exhibit in San Francisco
* As seen on Wired.com:
- "there is a certain beauty in manipulating theoretical light and angles of refraction and watching what happens"
* Also seen on iPadCreative.com:
- "That light prism simulation app looks fantastic. I'd love to play around with it."
* Also seen on KRON TV San Francisco
DESCRIPTION
Prism uses sophisticated ultra-fast ray-casting to simulate tens of thousands of individual rays of light as they pass through a variety of colored or clear glass prisms. As you move and rotate the prisms and the light-source, the light reacts instantly to your touch, sending showers of beams across the screen. The beams combine and split in a fantastic array of natural rainbow patterns that you will recognize from the real world around you, but have never been able to interact with as freely before. The result is a beautiful and surprisingly emotional experience.
FEATURES
* Simple controls.
* 12 beautiful pre-set scenes.
* Every scene can be easily customized.
* Fully multi-touch so that friends can play at the same time.
* Dynamically adjusts to the capabilities of your device to maximize the visuals.
(Currently tuned for iPad2, iPad, iPhone4, iPhone3GS, iPhone3G, and even iPod Touch 2)
* Regular prisms: triangles, squares pentagons, etc.
* Star-shaped prisms with any number of points.
* Perfectly circular prisms.
* Each prism's shape and color can be modified.
* Realtime control of optical properties such as the Index of Refraction and Cauchy Coefficient.
* Written in 100% Objective-C and OpenGL for maximum performance.
* Many natural phenomena are accurately reproduced:
** Refraction, Dispersion, and Partial Transmission
** Snell's Law and Total Internal Reflection
** Caustic Reflections ( Have you ever noticed the curved reflections of light inside a coffee cup ?)
** Natural Rainbows are easily illustrated using a circular prism
UNDER THE HOOD
each ray of light obeys three simple laws of optics:
* Refraction
- Light bends as it passes from one medium to another.
* Dispersion
- Blue light 'refracts' more than red light.
* Transmission and Reflection
- When light passes from one medium to another, some of it passes through and some is reflected.
when these simple laws are combined with the amazing power of today's handheld devices,
the results will amaze you.
