Setup & Capture
Yet another shoe scanning experiment, this time with some big improvements to the turntable setup and general workflow. After doing a load of research and picking up some new kit, the turntable is now ‘semi-automated’. The automated part is comprised of a rotating time-lapse head and a DSLR camera with an inbuilt intervalometer.
Not quite a one button solution yet, but other than rearranging the tripod and lighting stands for each level of capture, it’s a pretty stress free setup and no longer requires a person to hunch over and rotate the subject in hundreds of tiny increments!
See below shoot time-lapse.
After processing the images, the raw data turned out much better than any of my previous tests. The semi-automated setup might have something to do with this, due to there being less human intervention and therefore less room for human error (clumsy hands knocking things over).
For this test I also increased the image count to 500 and improved the camera spacing for better coverage of the subject. In my experience, capturing the interior of the shoe is always the hardest part; by adding in the vertical camera ring it seemed to really help with filling in some of the more difficult areas.
The next step is to split the model up into all the individual parts that make up the shoe. I have recently moved over to Maya for any manual retopology; using Quad Draw with Live Mesh turned on, I have found that you can quickly block out the basic shapes and then add in extra resolution which automatically shrink wraps to the surface of the scan – if you’re interested check out this tutorial by Autodesk.
See below images to demonstrate the basic retopology workflow between Maya and Zbrush.
Unfortunately I haven’t been able to find time to complete the shoe, but I hope people find this post interesting all the same. As always, I am interested in feedback, so feel free to get in touch if you have any questions or ideas on how to improve on this turntable setup.
Once I have eventually remodelled the shoe and cleaned up all the textures, I will be updating this post with some rendered turntables. Stay tuned…!
