Picture of Mutating a Homeworld 2 Scout Ship
This instructable details work done by Matthew VanStaalduinen (a mechanical engineering technology student at UNC Charlotte) using 123D Catch, Meshmixer, and a VFlash 3D printer from 3D Systems to create (and modify) a physical representation of a virtual object from the game Homeworld 2.

Step 1: Tools and Software Required

• A video game where a full 3D view of the object can be obtained
• 123D Catch*
• Mesh mixer*
• A 3d printer (a V-flash from 3D Systems was used in this project) or access to one of the online 3D print services
• Flush cutter pliers
• A computer capable of running the software
*The software is free from Autodesk

Step 2: Select and Object!

Picture of Select and Object!
The process we will be using is called photogrammetry.  We will be taking photos of an object in real life or screen shots virtually of an object, and turning them into real solid parts using a 3D printer.  The technology is advancing rapidly and has many uses in the engineering and medical fields. 

Find an open area in the game where an all-around view can be obtained of the object. There can’t be any reflective parts or other objects blocking the view, also the object must contrast with the background. Then take a large number (depending on the object, this one took around 100) of screen shots of the object from all angles as to cover every surface of the object. If there are any tool bars or constants in the pictures, they will need to be cropped out.

I love the Homeworld and Homeworld 2 games
you could always try entering the files that the game uses for storing the 3d model and copying it out of there. i know some games use 3d models in common formats like .obj other formats could be converted using online services.

Thanks for the instructable

You can use a 3D Model Ripper software to do the same more easily though

Nice idea!
Never thought of using screen-shots for that :)

One Q thou: What is the printer you used to print the STL's? The support-Plate looks nothing familiar...
That is awesome! What a great way to use catch :)

I'm so happy you published the results, I have wanted to do this with Link from Zelda (N64) since Catch came out.

Thanks for posting this!
