UPDATE: Art has been updated since the original post.
For the November issue of 3ABN World, we needed to illustrate a devotional article based on the famous Apollo 13 mission. After a futile search for a useful clipart image, I decided to take the plunge and make my own composition. Keep in mind that I do not have much experience in 3D — I think I could count my 3D illustrations on one hand — and I had only six hours or so across two days to work on this. Besides that, my tools were a clunky 3D application called Swift 3D 4.5 (nothing “swift” about it), SketchUp 6, and Photoshop CS2.
I found a number of 3D models. Interestingly, each one was different in various ways, including in regards to the colors and materials used for major pieces of the Apollo command module. So I compared them all, noted the common features, and also perused some online articles about the Apollo 13 mission (characterized by fuzzy, black and white images). In the end, I went for as accurate as I could guess, along with adding a few random stylistic elements that are almost certainly not true to life, but which make it look more believable.
Here is the base model that I downloaded. Note the absence of color and detail, and that the dish antenna is completely missing:

I added basic colors, materials, and textures in Swift 3D, and got the angle set to what I wanted. Then I exported it as a PNG image, and opened that in Photoshop. Then I added more color, shading, and texture. I also added lettering, rivets, the words “United States,” and other little do-dads. In the background I added stars (using a real photo of the night sky, not just random stars), and a view of Earth.
Originally I had added a dish antenna borrowed from another model, which I retouched in Photoshop. But I was not happy with the result. The new graphic below shows the new antenna that I made from scratch using SketchUp, Swift 3D, and Photoshop.
Here is detail of the craft:

Here is a small version of the final image. The full size one is 11 inches wide at 300 ppi.

it looks like a pencil top
Very funny, Susan. That’s because the front is covered in something that looks like polished copper.
Wow, that’s amazing. You could put me in solitary confinement for years before I’d be able to do that!
