Designers have been trained to think either in two-dimensions (graphics and drawing) or in three-dimensions (physical and computer models) but not necessarily in terms of combining 2D with 3D into a new language of visual communication. Merging of two and three dimensional representation or what I call “5Dthink” - is a strategy of thinking (and designing) in simultaneous layers - creating design visualization that has never before been so available, rapidly generated, affordable and easy to learn!
I will continue to explore 5Dthink in future blog posts, but wanted to quickly present an example of what I believe is the next generation of visual communication. The test perspective below combines 3-dimensional modeling with 2-dimensional drawing. It seamlessly integrates three separate software programs (Google SketchUp, SU Podium and Adobe Photoshop), digital reprographics and traditional hand drawing. The end product is a hybrid image that represents the merging of high technology and hand drawing.

Step 1: Base SketchUp Model. For this test, I downloaded a house model from 3D Warehouse and added some basic landscaping. I did not include people in the scene. Basic default lighting and shadow adjustment emphasized the deep porch and roof overhangs.
Step 2: SketchUp Model Preparation. In advance of the rendering process, I adjusted the SketchUp model “shadow settings” to Dark 25 and Light 35. This significantly darkened the model view but was necessary to pop the shadows in the rendering process.
Step 3: SU Podium Rendering. Rendered in just over 6 minutes, this image was created with the SketchUp plugin SU Podium generated a photo-realistic rendering of the house with accurate light modeling (compare the shadows on the four front porch columns) and reflective glass on the windows. This 3D digital rendering was far superior to the exported SketchUp scene, but was only an interim step in my 5Dthink process. Time to add 2D!
Step 4: Image Photoshop Filtering. I filtered the image using the filter>artistic>watercolor tool which popped many of the edges and added contrast to the wall and roof textures. This also masked the photographic dominance of the trees by giving them a more painted appearance.
Step 5: Image Printing. Again in Photoshop, I created a duplicate layer of the background image and adjusted the transparency to 75% of the original intensity. This significantly lightened the image - a necessary step in preparation for adding markers, colored pencils and hand delineation. I printed the image on my Epson Workforce 1100 at 7”x15” on Epson photo quality ink jet paper (matte finish smooth coated paper).
Step 6: Hand Drawn Character. Using a few light colored Chartpak AD markers, I added back color to the windows, walls, roof, grass, trees and landscaping. I did not color the sky. I overdrew the building edges with multiple overlapping pencil lines which gave the image such a hand drawn appearance. Several colors of Prismacolor pencils were used on different surfaces. Final white pencil highlights and black pencil stipple transformed the computer image into what now appears as a hand drawn rendering!
