Demo effect

The demo effect is a name for computer-based <a href="/facts/Real-time_computer_graphics/jrILnb0K">real-time</a> <a href="/facts/Visual_effects/AdoEkAWU">visual effects</a> found in <a href="/facts/Demo_(computer_programming)/yKunscS7">demos</a> created by the <a href="/facts/Demoscene/yKunscS7">demoscene</a>.
The main purpose of demo effects in demos is to show off the skills of the programmer. Because of this, demo coders have often attempted to create new effects whose technical basis cannot be easily figured out by fellow programmers.
Sometimes, particularly in the case of severely limited platforms such as the <a href="/facts/Commodore_64/3TPcKDbb">Commodore 64</a>, a demo effect may make the target machine do things that are supposedly beyond its capabilities. The ability to creatively overcome major technical limitations is greatly appreciated among demosceners.
Modern demos are not as focused on effects as the demos of the 1980s and 1990s. Effects are rarely stand-alone content elements anymore, and their role in programmer showcase has diminished, particularly in <a href="/facts/IBM_PC/yhcJGMPL">PC</a> demos. As for today, PC demosceners are more likely to demonstrate their programming skills with <a href="/facts/Procedural_generation/I94vq0AQ">procedural content generation</a> or 3D engine features than with superior visual effects.
