It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces. It is based on Bui Tuong Phong 's informal observation that shiny surfaces have small intense specular highlights , while dull surfaces have large highlights that fall off more gradually.
Shiny is a web framework for developing web applications (apps), originally in R and since 2022 in python. It is free and open source. [2] It was announced by Joe Cheng, CTO of Posit, formerly RStudio, in 2012. [3] One of the uses of Shiny has been in fast prototyping. [4] In 2022, a separate implementation Shiny for Python was announced. [5]
Historically, rendering was called image synthesis [6]: xxi but today this term is likely to mean AI image generation. [7] The term "neural rendering" is sometimes used when a neural network is the primary means of generating an image but some degree of control over the output image is provided. [8]
The first sheet can be typed, drawn, or written upon. The second sheet is coated with a layer of wax that had been impregnated with one of a variety of colorants. The pressure of writing or typing on the first sheet transfers the colored wax from the second sheet to the shiny, coated back side of the first sheet, producing a mirror image.
Sixel encodes images by breaking up the bitmap into a series of 6-pixel high horizontal strips. Each 1-pixel-wide vertical column in a particular strip forms a single sixel. Each sixel's pixels are read as binary and encoded into a single 6-bit number, with "on" pixels encoded as a 1.
Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
The ImageNet project is a large visual database designed for use in visual object recognition software research. More than 14 million [1] [2] images have been hand-annotated by the project to indicate what objects are pictured and in at least one million of the images, bounding boxes are also provided. [3]
