Cone

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.

More precisely, it is the solid figure bounded by a base in a plane and by a surface (called the lateral surface) formed by the locus of all straight line segments joining the apex to the perimeter of the base. The term "cone" sometimes refers just to the surface of this solid figure, or just to the lateral surface.

The axis of a cone is the straight line (if any), passing through the apex, about which the base (and the whole cone) has a circular symmetry.

In common usage in elementary geometry, cones are assumed to be right circular, where circular means that the base is a circle and right means that the axis passes through the centre of the base at right angles to its plane. Contrasted with right cones are oblique cones, in which the axis does not pass perpendicularly through the centre of the base. In general, however, the base may be any shape and the apex may lie anywhere (though it is usually assumed that the base is bounded and therefore has finite area, and that the apex lies outside the plane of the base).

Sony Vegas Pro

Sony Vegas Pro is a video editing software package for non-linear editing (NLE) originally published by Sonic Foundry, now owned and run by Sony Creative Software.

Originally developed as an audio editor, it eventually developed into an NLE for video and audio from version 2.0. Vegas features real-time multitrack video and audio editing on unlimited tracks, resolution-independent video sequencing, complex effects and compositing tools, 24-bit/192 kHz audio support, VST and DirectX plug-in effect support, and Dolby Digital surround sound mixing. Up to version 10, Vegas Pro runs on Windows 7, Windows 8, and Windows 10. Version 11 dropped support for Windows XP, and version 12 is 64-bit only. Version 13 dropped Windows Vista support.

Features

Vegas does not require any specialized hardware to run properly, allowing it to operate on almost any standard Windows computer across a broad range of hardware.

In areas of compositing and motion graphics Vegas provides a broad tool set including 3D track motion compositing with control over z-depth, and spatial arrangement of visual planes including plane intersection.

Canon EOS 600D

The Canon EOS 600D is an 18.0 megapixel digital single-lens reflex camera, released by Canon on 7 February 2011. It is known as the EOS Kiss X5 in Japan and the EOS Rebel T3i in the Americas. The 600D is the second Canon EOS camera with an articulating LCD screen and supersedes the 550D, although the earlier model was not discontinued until June 2012, when the successor of the 600D, the 650D, was announced.

Free music

Free music or libre music is music that, like free software, can freely be copied, distributed and modified for any purpose. Thus free music is either in the public domain or licensed under a free license by the artist or copyright holder themselves, often as a method of promotion. It does not mean that there should be no fee involved. The word free refers to freedom (as in free software), not to price.

The Free Music Philosophy generally encourages creators to free music using whatever language or methods they wish. A Free Music Public License (FMPL) is available for those who prefer a formal approach. Some free music is licensed under licenses that are intended for software (like the GPL) or other writings (the GFDL). But there are also licenses especially for music and other works of art, such as EFF's Open Audio License, LinuxTag's Open Music License, the Free Art license and some of the Creative Commons Licences.

History

Before the advent of copyright law in the early 18th century and its subsequent application to music compositions first, all music was "free" according to the definitions used in free software or free music, since there were no copyright restrictions. In practice however, music reproduction was generally restricted to live performances and the legalities of playing other people's music was unclear in most jurisdictions. Copyright laws changed this gradually so much so that in the late 20th century, copying a few words of a musical composition or a few seconds of a sound recording, the two forms of music copyright, could be considered criminal infringement.

Royalty-free

Royalty-free, or RF, refers to the right to use copyrighted material or intellectual property without the need to pay royalties or license fees for each use or per volume sold, or some time period of use or sales.

Computer standards

Many computer industry standards, especially those developed and submitted by industry consortium's or individual companies, involve royalties for the actual use of these standards. These royalties are typically charged on a "per port" basis, where the manufacturer of end-user devices has to pay a small fixed fee for each device sold, and also include a substantial annual fixed fee. With millions of devices sold each year, the royalties can amount to several millions of dollars, which is a significant burden for the manufacturer. Examples of such royalties-based standards include IEEE 1394, HDMI, and H.264/MPEG-4 AVC.

Royalty-free standards do not include any "per-port" or "per-volume" charges or annual payments for the actual implementation of the standard, even though the text of the actual specification is typically protected by copyright and needs to be purchased from the standards body. Most open standards are royalty-free, and many proprietary standards are royalty-free as well. Examples of royalty-free standards include DisplayPort, VGA, VP8, and Matroska.
