A rendering of the candle holder
Now that the days are getting shorter, it may be a nice home decorating idea to create a decorative candle holder. Having the powers of SketchUp and computational design methods as well as 3D printing at our fingertips, it does, of course, make sense to create something more interesting than just a boring lampshade.
This brief example uses the patterned panel exercise from Chapter 7 to create the basic geometry. Of course you can replace the sinusoidal wave pattern easily now with another beautiful function, or you could even have the cutout pattern generated based on colors in an image, which allows you to make it look like a logo, landscape, etc.
Since the resulting shape needed to have the pattern cut into a curved surface, there were basically two approaches: 1) create a curved surface and place the geometry onto it by arranging it radially (and then subtracting it), or 2) creating the panels flat and...
I came across brick wall designs today where the architects were considering various options with pulled bricks. This design approach has been used before in many different ways but the basic principle is always the same: In a brick wall that is dominated by stretchers, you insert strategically placed headers which then protrude a little bit beyond the brick wall surface. This creates a very nice pattern with interesting shadows. The first image below shows such a design in a SketchUp model:
A wall with evenly pulled bricks
Given that in reality these are placed manually it may be reasonably easy (and therefore not too costly) to vary the extend of their extension beyond the surface and thereby create more interesting undulating patterns. One such pattern is shown below:
And one with a sinusoidal pattern
As it turns out, this is very easy to do by simply modifying some of the scripts from Chapter 7 and combining coding with a carefully created SketchUp model....
These days, there are quite a few ways in which we can share a SketchUp model with the world, thanks to a technology that is built right into most modern browsers: WebGL. One example is Trimble's 3D Warehouse, where an uploaded model becomes an interactive one just by clicking on a small icon:
Other web services expand on this technology. Of those, Sketchfab offers amazing possibilities when it comes to adjusting the model and its materials after upload. Using its 3D Editor, you can tweak the interactive WebGL model quite a bit. Here is an example of an edited SketchUp model.
I covered the process of preparing a SketchUp model, uploading, and adjusting it in a recent guest post on the Sketchfab blog. You can read it at the link below. Feel free to discuss anything related to this process in the comments below this post.
Below is a link to the original Sketchup model:

Did you see my 2015 Christmas card tree image on this site? In case you were wondering how I modeled and rendered it, here is a video that explains that process. It's a bit of a minimalistic design, but as you can see in the video, I used a bunch of SketchUp extensions and the Twilight Renderer to make it happen. I hope you find the tips and tricks useful for your own projects.
Covered topics: studio setup, materials, Erode extension, components, scale tool, Fredoscale extension, Selection Toys extension, Profile Builder extension, Twilight extension, Twilight materials, Twilight lights, Twilight rendering options.

Just a quick heads-up: The SketchUp folks just posted a set of videos that explain how to create better models for sharing on the 3D Warehouse. I am linking to the videos and post here because I have way too often come across models where the scale was off, the component nesting didn't make sense, textures were too detailed etc. This is especially crucial if there might be a desire to 3D print them later.
