RayLab vs ColorAssim

RayLab is an application for design and simulation of optics. It can be used either as a learning tool or for the design of real optical systems. Basic version includes: • Ability to model 2D lenses and mirrors • Full control over placement and shape of optical components • Full control over aspheric surface shape parameters • Full geometric ray tracing • Sequential and Non Sequential analysis • Front Focal Length, Back Focal Length, Principle Surface calculations • Sample Models Upgrade to RayLab Pro enables: • 3D Modeling • Advanced Optical Elements such as Lens Arrays, Diffraction Gratings, Prisms, Fresnel Lenses, etc. • Polarization Ray Tracing * Ray Splitting / Beam Splitter modeling • Multi-Configuration Manager and animation functionality • Ability to perform optimizations of design parameters • Ray Transfer Matrix calculation • Various commercial glass catalogs • Zemax Importer • Multiple Analysis Windows: -- Fan Ray Diagram. -- Wavefront Error Plot. -- Grid Distortion Plot. -- Spot Diagram. -- Chromatic Aberration. -- Gaussian Spot Size. -- Polarization Analyzer. Upgrade is available with in-app purchases of various modules OR as a full featured subscription. • The subscription offers a 7 day free trial period. Subscription begins immediately but payment will only be charged to iTunes Account at the end of the trial period. • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. • The account will be charged for renewal within 24-hours prior to the end of the current period, at the same monthly price as the original subscription. • You may manage your subscriptions and auto-renewal may be turned off by going to your iTunes Account Settings after purchase. • No cancellation of the current subscription is allowed during active subscription period. • Any unused portion of a free trial period will be forfeited if the subscription is cancelled.

Color assimilation was first described by Wilhelm von Bezold 150 years ago: when thin colored stripes are overlaid on an image, the colors of the image appear to shift toward the stripe colors. With time, these illusions have become increasingly dramatic — from the classic Bezold spreading effect to the Munker illusion, the Monnier-Shevell illusion, and most recently the Confetti illusion by David Novick. We find that color assimilation works particularly well with human faces. ColorAssim lets you experience this directly: take a selfie or a portrait, and the app automatically segments your face and renders it nine ways — across three color sets (RGB, black-gray-white, and CMY) and three stripe phases. Watch the same face appear red, green, blue, yellow, cyan, and magenta, all at once, just by changing the color of the overlaid stripes. The effect is not a filter. Your face hasn't changed — only your perception of it has. Don't believe it? Tap the image, and the stripes covering the face fade away to reveal the unchanged colors underneath. Pinch to zoom in on the very pixels: they stay identical while the illusion comes and goes. Tap again, and the colors snap back. Share the result or save it to your photo library — with or without the stripes. And the little "?" button explains the science behind the effect.

Just use the oval region when the segmentation gives a warning message!
