This project enables drawing on very large surfaces with Gimp. The LightTwist system is used for large scale projection, thereby allowing the use of multiple projectors to cover large arbitrary surfaces.
Gimp was modified to send over the network (using multicasting) the image changes as they occur, in real time. This is how communication with LightTwist is established and makes it possible to display on a large scale. Gimp is not limited to a simple screen anymore!
Thanks to multicasting, it is possible to use multiple Gimp on different computers to draw on a single image at the same time. It is therefore possible to use Gimp for collaborative drawing, which is great when the images are so large…
The multi-Gimp protocol is not finalized. Some problems with undo and people drawing at the same place at the same time remains to be solved.
This project is an original idea of the Vision3D Lab, in collaboration with Daniel Danis, writer and dramaturge, and is developped in collaboration with Numédiart, research program in Digital Art Technologies at Faculté polytechnique de Mons (Belgium).
The persons directly involved in the developpement are:
- Radhwan Ben Madhkour, Numédiart
- Vincent Chapdelaine-Couture, Lab Vision3D
- Lucie Bélanger, Lab Vision3D
- Sébastien Roy, Lab Vision3D
