The Scene Portal - The HiRes Scene 

VGA stands for Video Graphics Array, a video mode and capability designed to display graphics on a CRT. In terms of the "scene", a VGA is generally referred to as any picture or image drawn with a computer painting and/or rendering program, in any video mode (but most commonly, in the VGA (640x480x256) or higher (SVGA) video modes.) Some of the more commonly used programs are Adobe Photoshop(tm), Corel PhotoPaint(tm), Autodesk 3D Studio(tm), and 3DS Max(tm).

In general, the styles used to draw a "VGA" are very diverse - but they can be divided into two large categories, rendered and non-rendered work. Rendered work, as the name suggests, is art drawn with the aid of a computer rendering program, such as 3D Studio(tm) or POV Raytracer(tm). Non-rendered work is a hand-drawn, "freestyle" form of drawing, which encompasses everything from airbrushing to pixel-by-pixel artistry.
