If you've ever taking an art class you might have heard of the term "Rapid Visualization"...a name given to a drawing technique that allows the artist to develop an idea from early concept all the way through to a finish product, all while never starting over along that path of development. A drawing technique that "evolves" as you keep moving forward. For those of you that enjoy surfing Wiki, the official definition of this technique is as follows:
Rapid visualization (also known as rapid vis) is a technique used by graphic artists to create a drawing of a concept in several stages. After the completion of thumbnail drawings, a preferred drawing is selected and rendered in full size, usually in pencil. Then a sheet of paper (layout bond) is put over the drawing and it is redrawn/traced with corrections, additions, and alterations. This process is repeated several times, often with color added at some stage, until the image is perfected to the desire of the artist.
The purpose of rapid vis is to take an idea from concept to accurate rendering without having to start over from scratch each time an edit or alteration is desired. The completed drawing is usually still considered a rough layout or comprehensive for approval submission (as opposed to finished art for framing or camera-ready art for reproduction).
In true BIMevolution form, my hopes are to help redefine and repurpose the "Rapid Visualization" technique as it can be applied to the ever "evolving" pieces of BIM. So what are those evolving pieces?
- The Model itself - Level of detail and visualization needs throughout all phases
- The "i" in BIM - the Information attached to elements within the model that will be used throughout all phases (4D, 5D, 6D, and beyond)
If you take away the "i" you're left with a "BM". (i know what you're thinking here) or in more politcally correct terms the "Building Model". This model is constantly changing from design concept through final design, and asbuilts. Rapid Visualization, as it will be discussed in later postings, will focus on the evolving Level of Detail (LOD) in the model and the visuals needed for design approvals, etc.
How Does Rapid Visualization Apply to the "i" in BIM?
All too often I see companies focusing on the "BM", while rarely concerning themselves with the "i". This might be OK if you're only building a model to generate Construction Documents. I however, believe that BIM's true potential lies in the evolution of the "i" or "Information" being generated throughout design and all phases beyond. In true artist form, the Rapid Visualization approach allows us to conceptualize, define and append to the "i" in BIM...all while refraining from building silos of information that typically require multiple players at the table to start from scratch as design changes occur.
