COLLABORATIVE SPACE
Directions for use
Contents of the different possibilities offered to
the users when entering the laboratory :
To work in the collaborative space, the users could arrange to meet together,
fix a date and time when they will connect and work together in the same
space, they can also determine a duration for the performance.
Then we could give them the possibility to propose this performance to
everybody who wish to participate (every user able to connect to the E-galab
site) or to lock the performance for the persons of their choice (for
example for a private performance).
Anyway, every person entering the site, will be able to see the performances
in progress (even the private performances).
So we have to think about different « rooms » proposed when
entering the Laboratory :
- First- the previous works :
The user will be able to see the works made previously in the collaborative
space and observe the evolution, step by step, through the form of a movie
; the work is the entire evolution including each transformation of the
performance.
- Second- the works in progress :
If there is a performance in progress, the user can be spectator of it.
- Third- the futur works :
Users can fix a date and time when they will connect and work together
for a certain length of time.
Directions for use
The collaborative space is a 3D space with a vrml navigation system in
which several users can connect and work together in real time on and
with the same materials.
Each user have a dissociated point of view and is able to see each transformation
made by the others.
There is no possibility to lock the works in progress, so each user have
to be aware that their work could be transformed at any time by anyone.
The idea of sharing the works is primordial and is one of the central
points of this project. Another important idea is the multiplicity of
points of view on a work in progress.
Before entering the collaborative space, the users have to upload their
files to the E-galab server by selecting items in the different categories
(2D,3D,movies or sound), and then update this category.
Once in the 3D space, users can work with all the files inside the server
(it means their own files but also files of the others), they have the
opportunity to create many different objects and insert them in the virtual
world. These objects can be transformed at any time by anybody connected
to this world.
Objects can be manipulated by different persons at the same time.
List of tools offered to the users :
| Object |
Creation or importation of objects (plane surface, plane surface
with points, cube, sphere, cone, cylinder) and 3D objects in vrml
; possibility to name, delete or change the form of each object.Each
time a new object is created, it appears at the same place, i.e at
the original point of view. To go to this point of view, there is
a navigation tool from the cortona window called « restore ». |
| Texture |
4 possible textures : still image, video, sound or typing text. |
| Move |
Give an object any position in the space by manipulating the 3
axes x,y,z. |
| Rotate |
To rotate the object in the 3 directions. |
| Scale |
To scale object |
| Pull |
Affiliated to the « plane surface with points » object
and allows to grab and drag several points, to give a 3D form to a
plane surface. |
| Transp |
To apply to the object a total transparency. |
| Memory |
To record the entire scene with all its manipulations ; it is then
possible to reload a scene and see all the transformations made step
by step. |
| Colors |
Allows to texture each object with a choice of colors and a scale
for each RVB colors. |
