Rendering is the process of generating an image from a model , by means of computer programs. A scene file contains objects in a strictly defined language or data structure; it would contain geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene...

Use
3CT is usually employed by industrialists and manufacturers in order to better serve and appeal to their clients. 3CT is most effective in cases where the client is also a CAD user. For example, a manufacturer of luxury furniture will use 3CT in order to accommodate architects that are almost all users of CAD programs.3CT superiority over paper catalogs
As CAD design has become largely widespread amongst designers from all domains, 3CT appears to be indispensable. A 3CT object could be injected into a project in an early phase of CAD design, as it is a virtual digital entity immediately exploitable by the designer. 3D catalogs are easier to browse and the users (The manufacturer’s clients) become well acquainted with the products.Process
Raw materials for a 3D Catalog could be obtained either by 2D/3D scanning or by exploiting existing CAD files of the yet to be created catalog objects. Such raw materials are called "Construction data" regardless of the way they are obtained. The construction data is then processed in order to modelize an as accurate as possible 3D object. The resulting object (usually called 3D Master) is then cut into various 2D projections: Top view (or plan) Front, Back, Right and Left views. The minimum 3CT standard is usually 6 files per catalogue object – one 3D file and five 2D projections.Conversions
Most 3D catalogs are intended to exist in several CAD formats. The aim is to reach an as large as possible users pool. Since every design domain has several available CAD programs.See also
