What is the Index of Refraction (IOR) for?
The Index of Refraction is a number that describes how much light bends when it passes from one medium to another. This value is crucial for creating physically accurate materials in 3D rendering, distinguishing between materials like glass, water, or diamond.
How many materials are included in IOR?
IOR includes over 250 materials, covering gems, glass, metals, liquids, biological tissue, crystals, polymers, and gases. These values are cross-referenced against published scientific sources like NIST and academic literature.
Can I see how light bends with IOR?
Yes, IOR features an interactive optical visualizer. You can adjust IOR and angle sliders to see how light bends in real time, demonstrating principles like Snell's Law, Fresnel Reflectance, Brewster's Angle, and Total Internal Reflection.
Does IOR explain the theory behind light bending?
Yes, the app has a dedicated Theory section that explains optics fundamentals such as Snell's Law, Fresnel equations, Brewster's Angle, and Total Internal Reflection. It includes interactive visualizers, equations, and curated video references.
Is IOR useful for 3D artists?
IOR is specifically built for 3D artists using renderers like Blender, Maya, Arnold, V-Ray, and Octane. It provides exact IOR values needed for physically accurate materials, eliminating guesswork and the need for constant online searches.
How much does IOR cost?
IOR is a paid application, available for $0.99. This one-time purchase grants access to all its features and data.
Does IOR have ads?
No, IOR is ad-free. As a paid application, it does not contain any advertisements, providing an uninterrupted user experience.
What devices does IOR support?
IOR is optimized for both iPhone and iPad, supporting both portrait and landscape orientations. It is compatible with devices running iOS.
