Welcome to my journal. This journal was set up to log thoughts and developments regarding my Second Life NASA Ames CoLab Project, the project proposal of which can be found at the beginning (first entry) of this journal. This journal was created to separate my CoLab project from my work experience project (a similar eco-system project), which can be found here: http://camden-mitchell.livejournal.com. The idea for this terraforming project was an initial consideration for my work experience based project, when I was brainstorming ideas based on 'creating an eco-system in a virtual environment'.
The current location for the prototype of my CoLab project can be found in Second Life at: Space CoLab Mars Island, Space CoLab (28, 211, 24).
If you would like to reference this journal in your own blogs etc, please leave notification in a comments section of this journal, or email me, and if possible contain a link. Thank you :-)
The journal will include images, mainly snapshots of Second Life, and chat transcripts. I will edit and format the transcripts in a way that makes them easier to read (mainly taking out the junk that can occur in between e.g. "user offline", putting sequential text from one person in one text block, and colour coding names).
If anyone has any objections to the images or chat, or feels like the edited chat transcripts misconstrue what was being said, please feel free to either comment on the relevant journal page, IM me in SL (Camden Mitchell), or email me at firstname.lastname@example.org. I will edit or remove the offending material.
The journal entries are in chronological order, oldest last to newest entries. I would do some html and create an index but I don't have time at the moment. Therefore, I will list all entries in the hope it makes it easier to navigate the journal. I have colour coded the entries for easier reference; blue = meetings & chats, green = project developments, red = design ideas. I apologise to anyone who is colour blind.

During January I worked on finishing the structure of the Euro-MARS habitat by including the upper deck (figure 1). This building work was carried out part time whilst reading through chapters in An Introduction to Astrobiology (Conway, A., Gilmour, I., Jones, B., Rothery, D., Sephton, M., Zarnecki, J. 2004. The Open University: Cambridge University Press.) to gather information on the differences between Earth and Mars, find out why life on Earth is abundant, and what kinds of life may survive on Mars during early terraformation processes.

Each room is individually textured to illustrate how Second Life residents living in the habitat can change the decor of their room, making the experience more personal, and signifying the importance of human factors in the real life mission).
The Euro-MARS habitat was not the main point of my project, which was to create a virtual environment. However, the building of the Euro-MARS took precedence when the director of the Euro-MARS project (The Mars Society U.K.) spotted my habitat in Second Life and expressed an interest in working together to complete the build to revised designs.
The requirements of using design material with officially obtained permission from The Mars Society U.K. were to make sure that all material was cited and credited to The Mars Society U.K., include a passive or active link to The Mars Society U.K. website (http://www.marssociety.org.uk/), and display The Euro-MARS/Mars Society UK project logo (figure 4).
The work on the Euro-MARS habitat was further made a priority by a request to have a copy of it to be on display in the teen-grid version of Second Life.
During February I continued to work on the habitat, which mainly involved making a few structural changes to fit in with new design plans, and applying texture and colour to the habitat to make it visually aesthetic (figures 2a - 3d). At it's current stage, some parts are still awaiting textures, such as the communications room (figures 2d and 2e). The choice of tiles in the bathroom area (figure 2f) is partly creative licence for the habitat simulation in Second Life, but also a consideration for human factors in the real life habitat.

After the restored prim count I needed to edit my original observation space station so that it was made of less objects (prims) to fit within the object (prim) allowance for my given parcel of land. I decided to remove a floor and decrease the diameter of the observation station, therefore enabling it to be built from a smaller number of side pieces.
Having a smaller diameter also meant that I had more room to put in an additional 'space' viewing booth. Figures 1a-1d document the process of creating a space within one wall panel to make an entrance to the adjoining viewing booth. The viewing booth itself would need separate floor, window and ceiling sections so that the relevant textures could be applied (e.g. the perception of being surrounded by space, and being inside a structure orbiting Mars).
(figure 1a. Editing a wall piece to make way for the viewing (figure 1b. diving the box up to separate wall, window, and ceiling
(figure 1c. Adding a floor texture, and seating area) (figure 1d. Evaluating the camera view form the seated position)
With the other viewing booth, I experimented with a bowed window shape to give more room within the structure (figures 2a and 2b). Although this design did provide more room the design was fidllier and required more prims to construct, which led to a tubular design as shown in figure 2c and 2d. A problem with both of the designs in figures 1c - 2b is that having the image applied to the inside structure would not have allowed for any perspective of the view; when the avatar moved the image of space would not appear realistic.
In figures 2c and 2d the structure can be seen to be constructed in a more simple fashion. There is a tubular cylinder section surrounding a rectangular box. The inner walls of the box are not visible due to a 'transparent' texture applied. This will act as the glass window, with the view of space texture being applied to the inside of the cylinder (figure 2f). The window texture in front of the space texture should aid the illusion of distance and perspective.
(figure 2a. Making the booth with a bowed window (figure 2b. More room provided to the booth but requires more
(figure 2c. Progression of the bowed window idea using a tubular section surrounding a box. This figure also shows the size of the viewing booth in relation to the new design of the observation station)
(figure 2d. Side view of the structure. The box is not visible (figure 2e. Outside view. The cylinder section is sealed off with a

(figure 2f. The inner walls of the box serve as the windows, whilst the inside of the cylinder and circle pieces have a 'space' texture applied. N.B. all textures were temporary and used as a visual aid).
After applying the example textures as shown in figure 2f, it became apparent that the illusion was still not quite right. Whilst the middle part of the view had some degree of distance, the cylinder structure met the bottom of the inner box, and therefore the image was not giving the required effect of a skybox.
To correct this I decided to totally encompass the inner box within another object, so that the space texture would give a better illusion when any avatar moved. This design process is illustrated in figures 3a - 3b.
(figure 3a. Encompassing the inner structure)
(figure 3b. Changing the shape of the outer sphere to better fit with the observation station exterior)
As can be seen in figure 3b, the interior surface of the hollowed sphere draws the map of the applied texture to a point at the poles. This would make it difficult to apply an accurate image of Mars as seen from space. The sphere was changed to a hollowed cube, as seen in figure 3c, which has a much more even texture map.
(figure 3c. Changing the outer object to a cube shape. As well as there being a more precise texture map on the inside of a hollowed cube, more distance between the inner booth and outer space image is gained, therefore increasing the viability of the illusion.
The next problem encountered was when the viewing booths were put in position (figure 4a). From inside one booth it should be possible to see into the other as they are positioned on the same side of the observation station. However, due to the space image being applied to the inner surface of the box structure, it was not possible to see past this.
The only way to get around this problem was to apply a large skybox that encompassed both viewing pods, and extend it to the areas of the observation station that could be viewed from the pods (figure 4b). Although this idea was previously considered, it was discounted on the basis that it would require a lot of objects to build the box, and all building was being done conservatively with regards to how many objects (prims) were used.
(figure 4a. Putting the viewing pods in position)
(figure 4b. Construction of a large Skybox surrounding the observation station, on which to place the images of Mars as seen from space)
Figures 4c - 4f illustrate how applying a larger skybox aids the illusion of being on an observation station. Each of the view pods can be seen from one another, and the distance between the space images and the viewing booth help to create a distance perspective. Figures 4b and 4c also show the difference in the size and shape of the observation station since its last redesign.

Prim count restored, therefore need to re- evaluate design of obs. station otherwise prim limit will be hit when Mars dome is installed, leaving too low a prim count left for Info Center displays.
Took out one floor of Observation station. Then decided just to rebuild and have less than the 18 sides it currently has.
- what would I consider changing in new rebuild of observation station?
