Tracing is the act of copying an image or work of art by drawing over its lines, especially through the use of transparent overlays. [1]
Tracing can provide a way for a person to develop their artistic skills for example when it comes to learning anatomy. It is however frowned upon in many art circles.
Rendering is the process of generating a photorealistic or non-photorealistic image from input data such as 3D models. The word "rendering" originally meant the task performed by an artist when depicting a real or imaginary thing. Today, to "render" commonly means to generate an image or video from a precise description using a computer program.
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.
Tracing may refer to:
In graphic design and advertising, a comprehensive layout or comprehensive, usually shortened to comp, is the page layout of a proposed design as initially presented by the designer to a client, showing the relative positions of text and illustrations before the final content of those elements has been decided upon. The comp thus serves as a draft of the final layout, and is used as guide for further design changes and, ultimately, production.
In public health, contact tracing is the process of identifying people who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. By tracing the contacts of infected individuals, testing them for infection, and isolating or treating the infected, this public health tool aims to reduce infections in the population. In addition to infection control, contact tracing serves as a means to identify high-risk and medically vulnerable populations who might be exposed to infection and facilitate appropriate medical care. In doing so, public health officials utilize contact tracing to conduct disease surveillance and prevent outbreaks. In cases of diseases of uncertain infectious potential, contact tracing is also sometimes performed to learn about disease characteristics, including infectiousness. Contact tracing is not always the most efficient method of addressing infectious disease. In areas of high disease prevalence, screening or focused testing may be more cost-effective.
Ray-tracing hardware is special-purpose computer hardware designed for accelerating ray tracing calculations.
Tracing paper is paper made to have low opacity, allowing light to pass through. Its origins date back to at least the 1300s, when it was used by artists of the Italian Renaissance. In the 1880s, tracing paper was produced en masse, used by architects, design engineers, and artists. Tracing paper was key in creating drawings that could be copied precisely using the diazo copy process. It then found many other uses. The original use for drawing and tracing was largely superseded by technologies that do not require diazo copying or manual copying of drawings.
Tracing boards are painted or printed illustrations depicting the various emblems and symbols of Freemasonry. They can be used as teaching aids during the lectures that follow each of the Masonic Degrees, when an experienced member explains the various concepts of Freemasonry to new members. They can also be used by experienced members as reminders of the concepts they learned as they went through the ceremonies of the different masonic degrees.
Unbiased rendering in computer graphics refers to techniques that avoid systematic errors, or biases, in the radiance approximation of an image. This term specifically relates to statistical bias, not subjective bias. Unbiased rendering aims to replicate real-world lighting and shading as accurately as possible without shortcuts. Path tracing and its derivatives are examples of unbiased techniques, whereas traditional ray tracing methods are typically biased.
Robert "Rob" Schamberger is an American painter known for his portraiture of professional wrestlers. He was the host of Canvas 2 Canvas on the WWE Network and YouTube until 2024.
The archaeological site Peñas de Cabrera, containing numerous rock shelters, is located in the municipality of Casabermeja (Spain). The entire surrounding area of Las Peñas de Cabrera, rife with natural minerals, rocks and fossils, is named after one of its districts of the same name. The entire complex of mountains and valleys consists of many shelters revealing rock art of paintings and engravings.
COVID-19 apps include mobile-software applications for digital contact-tracing—i.e. the process of identifying persons ("contacts") who may have been in contact with an infected individual—deployed during the COVID-19 pandemic.
Decentralized Privacy-Preserving Proximity Tracing is an open protocol developed in response to the COVID-19 pandemic to facilitate digital contact tracing of infected participants. The protocol, like competing protocol Pan-European Privacy-Preserving Proximity Tracing (PEPP-PT), uses Bluetooth Low Energy to track and log encounters with other users. The protocols differ in their reporting mechanism, with PEPP-PT requiring clients to upload contact logs to a central reporting server, whereas with DP-3T, the central reporting server never has access to contact logs nor is it responsible for processing and informing clients of contact. Because contact logs are never transmitted to third parties, it has major privacy benefits over the PEPP-PT approach; however, this comes at the cost of requiring more computing power on the client side to process infection reports.
COVID Tracker Ireland is a digital contact tracing app released by the Irish Government and the Health Service Executive on 7 July 2020 to prevent the spread of COVID-19 in Ireland. The app uses ENS and Bluetooth technology to determine whether a user have been a close contact of someone for more than 15 minutes who tested positive for COVID-19. On 8 July, the app reached one million registered users within 36 hours after its launch, representing more than 30% of the population of Ireland and over a quarter of all smartphone users in the country. As of August 2021, over 3,030,000 people have downloaded the app.
PathCheck Foundation is a volunteer-led nonprofit organization founded in February 2020 at MIT that develops COVID-19 apps for digital contact tracing. The organization consists of over 1000 volunteers. In addition, various companies donate employee time to the foundation. The organization was previously known as COVID Safe Paths but was renamed PathCheck Foundation on June 28, 2020.
Immuni was an open-source COVID-19 contact tracing app used for digital contact tracing in Italy, dismissed on 31 December, 2022, after a long and debated criticism for having been a failure due to the lack of trust placed by citizens. Immuni COVID-19 contact-tracing app had in fact been downloaded only by 12% of Italians between 14 and 75 years old. It makes use of the Apple/Google Exposure Notification system.

Valtrace is a contact tracing platform used in Valenzuela, Metro Manila. Its current role is to replace paper forms that increases possible contact with the virus. Valtrace uses QR code technology to provide contact-less tracing within the city. People who are going into the city's establishments should register to the program, in order to enter the establishment.
TousAntiCovid is a voluntary contact tracing app for monitoring the spread of the COVID-19 pandemic in France. It was first released on 2 June 2020 and is available on Android and iOS smartphones.
SafePass is a digital contact tracing app used as a response against the COVID-19 pandemic in the Philippines.
