Sterling is a fractal-generating computer program written in the C programming language in 1999 for Microsoft Windows by Stephen C. Ferguson. Sterling is now freeware while Sterling2 is a freeware version of Sterling with different algorithms. It was released in September 2008 by Tad Boniecki. Apart from the name (which shows as sterlingwar2 in the title bar and on the About screen), the program looks just like the original Sterling. The only internals that are different are the 50 formulae for fractal generation. Parameter files made by Sterling can be used in Sterling2 and vice versa, though they will draw different images.

Contents

Sterling is based on the notion that one way to generate interesting fractal images is by using elaborate color filters and shading. In many images, the main interest lies in the filters rather than the actual fractal boundaries themselves, as in traditional fractal-generating programs. The fractal merely serves as a seeding function to the coloring algorithms and filters. A feature of Sterling is the richness of the renders.

Sterling has a simple GUI interface with a limited number of functions. The program saves files as JPEG, BMP or one of six other formats. It draws in Julia mode, allows inside-out rendering and does anti-aliasing. It offers 32 different renders and four transform effects. There are three independent color controls and two ways to zoom into an image.

The Sterling2 ZIP file (436 KB) contains brief instructions. There is no installation it is enough to put the executable and dynamic-link library files in the same directory and start the exe file.

In 2018, the original code for sterling was released under the GPLv3.

The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers. There are also influences from the earlier Polyray raytracer because of contributions from its author, Alexander Enzmann. POV-Ray is free and open-source software, with the source code available under the AGPL-3.0-or-later license.

In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing, as well as general-purpose computing on graphics processing units.

Reyes rendering is a computer software architecture used in 3D computer graphics to render photo-realistic images. It was developed in the mid-1980s by Loren Carpenter and Robert L. Cook at Lucasfilm's Computer Graphics Research Group, which is now Pixar. It was first used in 1982 to render images for the Genesis effect sequence in the movie Star Trek II: The Wrath of Khan. Pixar's RenderMan was an implementation of the Reyes algorithm, It has been deprecated as of 2016 and removed as in RenderMan 21. According to the original paper describing the algorithm, the Reyes image rendering system is "An architecture for fast high-quality rendering of complex images." Reyes was proposed as a collection of algorithms and data processing systems. However, the terms "algorithm" and "architecture" have come to be used synonymously in this context and are used interchangeably in this article.

A scenery generator is software used to create landscape images, 3D models, and animations. These programs often use procedural generation to generate the landscapes. If not using procedural generation to create the landscapes, then normally a 3D artist would render and create the landscapes. These programs are often used in video games or movies. Basic elements of landscapes created by scenery generators include terrain, water, foliage, and clouds. The process for basic random generation uses a diamond square algorithm.

XYplorer is a file manager for Windows XP, Vista, 7, 8, 10, and 11. XYplorer is a hybrid file manager that combines features found in navigational and orthodox file managers. In addition to dual folder panes it features a file tree and a tabbed interface supporting drag-and-drop between tabs and panes. The program used to be available as Pro and Free versions. The Free version is still available as a feature-limited freeware version. The "Pro" was then dropped and just known as "XYPlorer". The program is available in a fully featured trialware version.

<span class="mw-page-title-main">Fractal-generating software</span>

Fractal-generating software is any type of graphics software that generates images of fractals. There are many fractal generating programs available, both free and commercial. Mobile apps are available to play or tinker with fractals. Some programmers create fractal software for themselves because of the novelty and because of the challenge in understanding the related mathematics. The generation of fractals has led to some very large problems for pure mathematics.

Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static or dynamic. CGI both refers to 2D computer graphics and 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects. The application of CGI for creating/improving animations is called computer animation, or CGI animation.
