Caustic (optics) - Wikipedia
In optics, a caustic or caustic network[1] is the envelope of light rays which have been reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. [2] .
Physics of Caustic Light in Water & Photography - On Landscape
2019年1月3日 · With modern computational algorithms, it is possible to do ray tracing for a wide variety of complex lighting situations, including the generation of caustics in rendering surface water surfaces 5. It is even possible to “reverse engineer” caustics.
Chapter 2. Rendering Water Caustics - NVIDIA Developer
Caustics result from light rays reflecting or refracting from a curved surface and hence focusing only in certain areas of the receiving surface. This chapter explains an aesthetics-driven method for rendering underwater caustics in real time.
Real-time rendering of water caustics | by Martin Renou - Medium
2020年8月27日 · Caustics are patterns of light that occur when light is refracted and reflected from a surface, in our case an air/water interface. Due to the reflection and refraction...
Caustic (optics) - Scientific logbook
2020年6月19日 · Caustics (wikipedia are luminous patterns which are resulting from the superposition of smoothly deviated light rays. It is for instance the heart-shaped pattern in your cup of coffee which is formed as the rays of the sun are reflected on the cup's surface.
Periodic Caustic Textures - Dynamic Graphics Project
Caustics are the evolving light patterns one often sees swimming pools, rivers, lakes and oceans. Sun light when it hits a water surface is reflected and refracted specularly in various directions. The water surface acts as a distorting lens focusing …
Large-scale ray traced water caustics in real-time using cascaded ...
2021年8月1日 · We introduce cascaded caustics maps to enable interactive accurate caustics rendering of vast scene regions with minimum performance drop. We incorporate photon differentials to improve photon flux density estimation and reduce noise and blur.
• Optical caustics are concentrated envelopes of light rays reflected or refracted by a curved surface of an object, or the projection of that envelope of rays on another surface • Familiar examples of caustics: rainbows, bright lines in water droplets and on the
2017年6月1日 · Caustics are complex physical phenomena resulting from the projection of light rays being reflected or refracted by a curved surface. In this work, we address the problem of classifying and removing caustics from images and propose a novel solution based on two Convolutional Neural Networks (CNNs): SalienceNet and DeepCaustics. Caustics result in
Caustics - University of Denver
2004年10月12日 · Minnaert mentions the caustics produced by drops of water on eyeglasses, and the resulting fringes. One of the most familiar sights produced by a caustic is the rainbow. The bright colors occur at the caustic surface between scattered light …
