Shapes and custom waves each have internal code that affects these variables similarly to how equations affect the entire preset. Custom shapes and waves equations are included in MilkDrop version 1.04 and later. While initially MilkDrop allowed four custom shapes and waves, the latest version of the MilkDrop beta allows up to five custom shapes and five custom waves to be utilized per preset. History Milkdrop is the successor of an earlier music visualization software by Ryan Geiss, the geiss plugin for Winamp, released around 1998. The geiss plugin did the real-time music visualization purely software rendered by utilizing the CPU effectively by highly optimized, hand-tuned assembly code. In 2001 the first version of milkdrop was written, built around the now widely available GPU hardware. Ryan Geiss released 12 versions of MilkDrop between 5 November 2001 and 31 July 2003. Originally closed source, version 1.04 Milkdrop's source code was released under the BSD license in May 2005. Geoff "Redi Jedi" Potter has taken up developing the program since 2005 and has released six beta versions. With the availability of the source code, MilkDrop has been ported to many platforms: for instance to XBMC (now Kodi), a homebrew developed media player that can be downloaded for Xbox, PC, or as a LiveCD. projectM is an implementation of MilkDrop using OpenGL in C++, and is released under the GNU LGPL. It is available as a plugin for Audacious, XMMS, Winamp, iTunes, Jack, PulseAudio, foobar2000, Windows Media Player, VLC media player and XBMC. The VLC versions 2.2.0 and higher no longer support the projectM plugin. It comes natively with Clementine, Poweramp, and Qmmp that are also available in the Play Store on Android. MilkDrop 2.0 was released in 2007, introducing Per Pixel Shader support. It is available with Winamp 5.5 or from projectM in their 2.0.1 version for use with other players like the VLC media player. MilkDrop 2 added DirectX 9.0 support and added the ability to use pixel shaders in its presets. The source code for MilkDrop 2.25c has been released on 15 May 2013. Milkdrop is implemented in Winamp (actual 5.66). Reception In 2011, Milkdrop was retrospectively described as "the greatest single work of art produced during the naughties". According to the Winamp main download page, the milkdrop plugin and its predecessor Geiss were the most downloaded plugins overall, with 2,737,890 and 4,686,010 downloads (on 10 August 2014), respectively.
