When communicating a design concept with a Google SketchUp model and hand drawings, it is valuable to understand viewing heights and how they can tell different stories about your subject.
I typically work with about four primary perspective viewing types: 1)eye-level elevation, 2) eye-level perspective, 3) roof-level perspective, and 4) aerial perspective. Each has a different emphasis and can be illustrated in the four different views of a SketchUp model shown below:
Option 1: Eye-level Elevation. This simple one-point perspective looking straight at the building facade emphasizes the architectural patterns of the windows, brick detailing and other basic information about the concept desing. Entourage (people, furniture, signage, etc.) add scale to the scene.
Option 2: Eye-level Perspective. This closeup eye-level two-point perspective is the most natural viewing height and easily informs the viewer about depth, layers of space, interior and exterior detail and overall placement of street elements, landscaping, signage and furniture.
Option 3: Roof-level Perspective. This three-point perspective view is established as if you were standing on a roof top or climbed up into a tree and looked down at the street scene. This viewing height is very effective in communicating more of a plan layout than if the scene were viewed at eye-level. Ground plane patterns are more easily understood from this elevated height.
Option 4: Aerial Perspective. This birds-eye perspective is quite effective when communicating large ground areas and for clearly visualizing patterns on the ground plain. Combined with an eye-level perspective, this overhead view illustrates plan relationships while the eye-level view captures the human scale relationships and emotion.
Sketch Example: Eye-level Elevation. This is a quick pen and marker elevation sketch of a building facade and exterior dining area. The architectural facade dominates the image.
Sketch Example: Eye-level Perspective. This sketch places the viewer into the space and has a natural "I am there" sense of the interior space.
Sketch Example: Roof-level Perspective. By raising up the viewing height of this quick sketch, the observer has a better understanding of the sidewalk pattern and lineal space connecting through a parking area to the building in the distance.
Sketch Example: Aerial Perspective. The birds-eye view successfully communicates building massing and the open spaces created between them. An aerial sketch like this paired with an eye-level view of the space is a very good visual combination to communicate the design concept.
