Questions to think about

Which part of the collection should be hidden? Why?
How to link with the X-Lib?
Based on which metadata variables are the shapes created?
Which feature would transform the 3D generated shapes into 3D printable files?
Who is using it? Only PZ?
What is the most important features?
Where would be situated? local? networked? physical space?
When would it be available? Temporary? Always?

Project proposal

What would be an alternative way of looking at the collection?

What?

How would it be possible to explore an exisiting book collection in a joyfull manner?

An addion to the X-Lib would be a 3D web interface, which creates customized stacks in forms of 3D shapes. These will generated based on the input of the hand drawings of the users. A serendipidian way of exploring a library. After the analysation process the metadata of the books will dictate a morphology of the shapes. Either round, spicky, robust, geometric or organic–each book has it's own character, which will be mirrored in the interface. Finally the reader will have the possiblilty to download the 3D shapes of the stacks and access the original content of the books in form of as a PDF. This project explores as well the alternative ways of representing books in digital libraries and aims to break the rigidness of square presentations. It aims as well to play with syntaxes of abuising file formats.

How will it be made?

The interface will be written in JavaScript. WebGL is an JavaScript API for rendering interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML5 <canvas> elements.

Why is it necessary?

This project approaches the interfaces in a serendipitian and subjective manner by using steganography, which is encoding and decoding information on 2D and 3D levels.

Relation to project as whole (how does it interface with the rest of the PZI library project) Relation to your self-directed research (how does it interface with previous work or abiding interests? what new interests are you following?) This project uses the similar way of thinking, but the outcome differentiats from the other encoding and decoding information on 2D and 3D level steganography (hiding information in other file formats) similar way of thinking, but using different software (webgl + js in this case)

Relation to your self-directed research and previous projects (how does it interface with previous work or abiding interests? what new interests are you following?)

remote access to the library

Issues arising

the knowledge of the software
how to connect the interface to the core library

Steps to take

→ Writing the source code of creating 3D shapes based on metadata (15.05–23.05)
→ Writing the source code of 3D steganography (MD5 hash or sim hash), which would decrypt informations in 3D shapes (15.05–23.05)
→ Writing the source code for code generator (18.05.–03.06)
→ 3D printing + 3D scanning testing (18.05.–03.06)
→ WebGL interface to create (18.05–23.05)
→ Testphase of the website + 3D printing + 3D scanning (24.05.–30.05)
→ Project documentation (30.05–03.06)
→ Presentation preparation (30.05–03.06)
