Slitscan textures & map generation

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 :)

gallery... again

I started a blog a year ago to document my work and some cool stuff that I'd happened upon the way. A few months later the site closed down and it was all gone... Downer!!

So now I'm back and starting a new blog. The aim of the blog is to mainly document my CG and photography work. I may post some influences in and amongst too..
