3D Visualization of an Alley Streetscape Project

Downtown alley looking westA while back I was working on a project to change an alley from a typical asphalt driveway to a pedestrian walkway. Because it is in a downtown area, this project allows for many design opportunities to enhance the downtown area and the pedestrian experience. During its planning stage, we had a lot of input from property owners, co-workers, and others in the community on what they wanted to see in that space. But as I put together the civil drawings, I thought it would be so much better to also have a 3D view of it so we could actually see what it would look like when we put in everyone’s ideas. I decided the easiest and fastest way for me to build the best looking model for this was to use something like Opensim or Second Life software. Due to the size and purpose of this project, I ended up setting it up in Second Life since I could make it in a premium sandbox, take a photo of it when done, and then store it in my inventory. Below is the result of my work.

If you look close, you will probably notice it really is not a perfectly executed model. This was intentional on my part. For this particular project, my goal was to see how fast I could set up a model that while not perfect was good enough for visualizing a design.This is because when I have built things like this before, one of the main questions I get from co-workers and other engineers is “how long did it take you to do that?” And in the past, I never really paid attention because I was more focused on the building aspect and trying to make it look exactly like the actual site. But for professional design work, time is one of the most important considerations. So I wanted to focus on how fast this could be done yet still achieve the goal. In the end, for this project, which covered roughly 30 feet by 400 feet, I would say it took about eight hours to take the photos, create the textures, and build the model. I might have been able to finish it sooner, but it took me a while to shop for the string lights and buy them in a Second Life store.

Here are a few more photos with different lighting and different views. Obviously with more time, a lot more elements could have been added and more ideas tried. The good thing about having a model like this is once it is built, it is so easy to just add other objects or try different designs:

Yes, anyone could walk through it with their avatar. It’s one of the aspects I like most about doing this in a place like Second Life rather than just building it in a regular 3D CAD program. So a group of people can meet there and feel as if they are visiting it together.
