The goal of a 3d rendering is to give your viewer an idea of what you are thinking, set in a realistic atmosphere. When viewing an image like this, there should be recognizable real world items that give a feeling of actual scale and what a person might perceive if the model actually existed. There are a number of different approaches that can be taken to achieve this.
Here are a few:
– A massing model is a very simple, exterior-only type of architectural 3D model, used to study the essence of the overall 3D form and proportions of an architectural design.
– A spatial model is an architectural 3D model with an intermediate level of detail, usually including some of both the interior and exterior of the structure. The spatial mode may not be fully realistic, but it usually allows exterior walk-throughs.
– A detailed model is a complete interior/exterior architectural 3D model, used to view an architectural design relatively realistically. A detailed model often includes material textures, and details like furniture and major ornamental elements.
