Architectural rendering is the conceptual illustration of an architectural design, often completed with the aid of computer software. Frequently used in schematic design presentations, these illustrations allow architects to inexpensively communicate a variety of construction possibilities to their clients. Photo-realistic renderings may be produced with the aid of professional-grade software as well as on a personal computer with less expensive or free 3D rendering software.

Novices desiring to create basic renderings of architectural ideas may use free software such as Google SketchUp. This software platform allows users to visualize construction ideas in a three-dimensional format, to publish these ideas online, and to insert these ideas into 3D maps.

A professional architect will probably prefer to purchase premium computer aided design(CAD) software to create an architectural rendering. Such software is enhanced with a variety of capabilities, permitting users to more easily navigate a 3D environment as well as to attach pricing and manufacturing information to objects represented within the rendering.

Architectural firms may also choose to develop an architectural rendering with the aid of other media, such as video cameras or solid models. Such media may be integrated to produce a fly-by presentation, allowing an audience to view a film presentation of a proposed architectural project.
