I purchased a cheap motorised turntable from China about a month ago.
This was intended to be used for a photogrammetry project but instead became
really useful for a different application.
Slitscan photography or temporal photography is typically used for photo-finish images in eg. the 100m sprint.
There are some examples where it has been used in a different way
This script by Martin Dixon processes a video file and extracts a strip of pixels. These are then stacked together
to form a single image.
I sat a bottle (empty) of beer on the turntable and switched it on. I then set up my
Nikon 3200D to shoot portrait hd video.
The processed file looks like this:
Taken into Photoshop and processed. I needed specular, diffuse, mix and normal maps
to create the final rendered version in 3ds max.
I created a simple studio style lighting setup and rendered using Vray. The model that I mapped it to is a generic bottle. At some point I will recreate an accurate Moretti bottle. This should complete the look.
Observations at this stage: The lighting while recording the footage needs to be more even as some of the colours are not accurate.
The normal map for the glass is a bit on the heavy side. It seems to be suggesting a condensation look.
The camera wasn't aligned correctly when I recorded the footage, and as a result the textures are wonky..
Other than that, I feel this is a pretty successful first attempt at seamless, (semi) automatically generated texturing for cylindrical based objects :)
