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 XPPL Volumetric Catalogue

First sketch of 3D stack

How would it be possible to explore an exisiting book collection in a serendipitous way?
An addition to the XPPL (space for potential pirate librarianship of the Piet Zwart Institute) would be a 3D web interface, which translates the metadata of the books into volumetric geometries. The morphology of the shapes is generated based on the string values of the book titles. Either round, spicy, robust, geometric or organic–each book has it's own character, which will be mirrored in the interface. By clicking on the specific shape the user will be linked to the API of the specific book. This project explores new ways of spreading information in the multidimensional environment, datavisualisation and alternative ways of representing books in digital libraries. It aims to break the rigidness of square presentation formats and plays with syntaxes of abusing file formats.
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.
This project uses the similar way of thinking, but the outcome differentiats from the other students. The fascination came from a long time research about encoding and decoding information on 2D and 3D levels, steganography (hiding information in other file formats).
During my previous project ACCP I started to explore different encoding and decoding systems for informations. This fascination became very intriguing for me, so therefor I decided to invest more time about it for a new project, which will explore the potential of hiding informations in 3D shapes. An other learning goal with this project to get familiar with JavaScript and WebGL.

The issues could arise on the technical level, since there is a limited time (4 weeks) to realise the whole project without JavaScript knowledge beforehand. An other issue could arise about the connection way of the original interface and 3D interface.

Steps to take

→ ~~Loading all the books in the .json file~~
→ ~~scenery creation (light, shadow)~~
→ ~~materiality of the shapes (material or color)~~
→ ~~rotation add to the shapes~~
→ ~~hover over mouse effect~~
→ ~~link the shapes with the books~~
→ ~~hosting online or offline?~~
→ ~~fine-tuning!!!~~

+''How would it be possible to explore an exisiting book collection in a serendipitous way?''
+<br>
+An addition to the XPPL (space for potential pirate librarianship of the Piet Zwart Institute) would be a 3D web interface, which translates the metadata of the books into volumetric geometries. The morphology of the shapes is  generated based on the string values of the book titles. Either round, spicy, robust, geometric or organic–each book has it's own character, which will be mirrored in the interface. By clicking on the specific shape the user will be linked to the API of the specific book. This project explores new ways of spreading information in the multidimensional environment, datavisualisation and alternative ways of representing books in digital libraries. It aims to break the rigidness of square presentation formats and plays with syntaxes of abusing file formats.
+<br>
+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.
+<br>
+This project uses the similar way of thinking, but the outcome differentiats from the other students. The fascination came from a long time research about encoding and decoding information on 2D and 3D levels, steganography (hiding information in other file formats).
+<br>
+During my previous project ACCP I started to explore different encoding and decoding systems for informations. This fascination became very intriguing for me, so therefor I decided to invest more time about it for a new project, which will explore the potential of hiding informations in 3D shapes. An other learning goal with this project to get familiar with JavaScript and WebGL.
+<br>
+The issues could arise on the technical level, since there is a limited time (4 weeks) to realise the whole project without JavaScript knowledge beforehand. An other issue could arise about the connection way of the original interface and 3D interface.
