A caustic is any substance capable of causing full-thickness damage on contact with healthy, intact tissue. Caustic agents are generally classified by pH as acids or bases. Irritants are those substances that do not produce true breakdown of tissue but cause discomfort and inflammation, such as vomiting, burning eyes, or coughing.

AbstractWe propose a novel system for designing and manufacturing surfaces that produce desired caustic images when illuminated by a light source. Our system is based on a nonnegative image decomposition using a set of possibly overlapping anisotropic Gaussian kernels.

The development of singular amplitudes, or caustics, in the propagation of a high frequency initially plane wave in a three-dimensional homogeneous and isotropic random medium with small (order O(h)) fluctuations in the index of refraction is investigated using geometrical optics.

Caustics Mapping: An Image-Space Technique for Real-Time Caustics
IEEE Transactions on Visualization and Computer Graphics, 2007In this paper, we present a simple and practical technique for real-time rendering of caustics from reflective and refractive objects. Our algorithm, conceptually similar to shadow mapping, consists of two main parts: creation of a caustic map texture, and utilization of the map to render caustics onto nonshiny surfaces.

Caustics of catadioptric cameras
Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002Conventional vision systems and algorithms assume the camera to have a single viewpoint. However, sensors need not always maintain a single viewpoint. For instance, an incorrectly aligned system could cause non-single viewpoints. Also, systems could be designed to specifically deviate from a single viewpoint to trade-off image characteristics such as ...

For a family of parallel incoming light rays, we consider the problem of finding a reflecting curve Γ that has as its caustic a given curve γ.

ESOPHAGEAL PERFORATION AND CAUSTIC INJURY: Emergency management of caustic ingestion
Diseases of the Esophagus, 1997Diagnosis and treatment of caustic ingestion injuries remain controversial. Based on experience with a wide spectrum of upper gastrointestinal tract injuries from caustic ingestion, prospectively observed in 58 adult patients treated in a teaching hospital in Milan, the authors suggest an early staging of the lesions by endoscopy, followed by resective

Caustic and corrosive substance ingestions are a significant cause of early and late morbidity and may cause esophageal carcinoma after a long latent period. Initial management should be directed at the assurance of adequate ventilation and cardiovascular stability as well as the prevention of vomiting. Early esophagoscopy (to the level of first lesion,

Proceedings of the 2008 symposium on Interactive 3D graphics and games, 2008
Interactive applications typically rely on local models for lighting, occasionally augmented by GPU-friendly methods for approximating global illumination. Caustic mapping approximates the specular focusing of light using a light-space image, akin to a shadow map, which is projected onto the scene during final rendering. Unfortunately, existing caustic
