3D rendering, as the name suggests, is a 3D version of graphic art derived from a design. Architectural and interior design 3D rendering are typically based on CAD software, translating plans in to images and even virtual reality shows.
Anyone who’s ever worked in design will tell you that the mainstream design market has a bad habit of being about 20 years behind the designers. That was the case with 3D rendering.
Bizarre as it may seem, 3D rendering wasn’t exactly welcomed by the design industry when it began. It was definitely not seen as an asset by the marketing gurus or the paper-based design industry. At best, it was considered a fad, not suitable for the real world marketplace. (Ironically, the industry had no problems with 2D rendering, but didn’t see why 3D rendering, in a 3D world, might work.)
Fortunately for the future of interior design and building design, the experts had their own design ideas about 3D rendering. These expert modellers patiently persevered with 3D rendering from its comparatively clunky beginnings to the current state of fluent rendering.
