세상에서 가장 쉬운 스케치업 강좌

스케치업을 통해 마치 핸드드로잉 수작업 일러스트 느낌을 내는 과정입니다.
뭐, 거의 리터칭에 가깝군요. 참고바랍니다. 

My previous blog post dated August 5, 2011 focused on developing an “Overlay and Trace” hand drawing from a Google SketchUp scene. This article is all about further investigating the many new options available for combining traditional hand drawings with digital image manipulation. I have cropped the original drawings in order to focus on the subtle differences between the variations. Each variation is explained below:

Original 3D Model and Hand Drawing

These two cropped images represent the original Google SketchUp 3D model and my hand drawing that was traced directly over a print of the SketchUp scene. My previous blog post explained the process and how I eventually colored the drawing with markers and colored pencils. I began at this point to explore different variations using the photorealistic rendering software by Shaderlight.

Shaderlight Rendering Variation

Left. I rendered the scene using Shaderlight Pro after assigning lighting characteristics to the individual wall sconces and lighting over the gift shop and restaurant area. Compare this view with the straight SketchUp scene (above) and notice the great difference in the quality of the light and sense of depth in the space.

Right. I imported my line drawing into Adobe Photoshop and combined the two images together to investigate the results. Notice that the ceiling linework appears in this composite image! Although the image was flat and lacking bright colors, I felt I was onto something important and continued exploring rendering variations in Shaderlight.

Shaderlight Chalk Render Variations

Left. The software program Shaderlight Pro has a rendering tool named “Chalk Render”, which renders the scene in only black and white shadows and lighting variations. The left image shows the results of this rendering tool as it reminded me of an architectural “white model” made from cardboard and photographed - a process many of us learned in architectural school. 

Right. I then combined the chalk rendered image with my hand drawn linework and was amazed at how this hybrid image had a realistic lighting effect combined with the illustrative character of my hand drawing. My next logical step was to now add color!

Final Color Variation. I combined my colored hand drawing with the Shaderlight chalk rendering in Photoshop to see if I could improve the quality of the image. The results were a mixed success and failure. The chalk rendering had given the windows a gray cast, so much that I need to erase all of the windows to brighten the image. Notice the column on the right side of the scene and how the chalk rendering has given the column a nice sense of depth and shadow. That was the effect I was searching for and hope to improve on my next project!
