Clothing hacking …
…so when you make something in Wings3D, the geometry forms a VERTEX (or 3d point) cloud. It’s solidity is comprised of polygons that are the result of the correct sequence of this “join the dots” to make FACETS that can then have visual properties of colour, texture, specularity, reflectivity, opacity and so on applied to them.
Hat polygon mesh
When you choose tools in wings to “color” each facet, it modifies the UV mapping of that facet when rendered in-world but the light model used by default (and no, for the life of me I cannot find how to change this) is a little odd – any colour you choose in wings is really, really light in-world (black looks light grey, blood red comes out light pink and so on). Wings has EXPORT as RWX, fortunately which is luck as RWX and COB are the two supported object definition formats Activewords seems to use.
The resultant RWX (object/model definition file) contains the locations of each vertex in x-y-z terms, relative to the centre point of the cartesian plane (0,0,0) where the object was sculpted, and the order these points are joined to make a polygon mesh [you will notice I have opened up the object file in notepad – geometry purists argue you do not need anything else than notepad to make objects – they are out of touch nerds who need to get a life in my opinion 😛 ]
TEXT object definition file - the RWX file
Fortunately, after breaking a bunch of RWX’s, I have stumbled across (yee gods, why does no one document this junk in a way HUMANS can read) a tweak – you can effect the overall colour and opacity of the model by defining the overall luminance – I have found 0.3 0.3 0.3 (for RGB) seems to work pretty well for most colours (except for yellow which comes out muddy and brown).
With some tweaking, my DeBono Hats finally look like they should:
iHatrack 2.0
These “player controlled” movers are worn – by clicking on them, users stick them to the heads of their avatars and they look quite cute (in a top-hatty sort of way). Punters, through their avatars adopt a DeBono thinking mode, and then you walk over and reflect on an issue using that mode – you can see in the background some kids have already started doing just that.
It is nice when an idea finally coalesces into the shape you wanted it to be (or is it just me being anal and doggedly plugging away at an unimportant detail until I am happy with it?) – prolly a little of column A, little from column B.
Grand Design …
So I raised [or does that mean demolished?] a mountain range to the south of the visitors centre on SciPrime with the express intention of building a science-based activity centre there. I elevated plateaus, ridges and sculpted ravines so it would be interesting terrain – incidentally it is the MOST fun place to drive over in a vehicle – such a fun ride. I can see why 4w drivers love to bush bash, in an activeworld however you do not get physically thrown around the cabin of your vehicle as you hurtle off a cliff and plow into a ridge.
a hole in the terrain
One of the “texture” options for elevated terrain is the ability to make the terrain tile a HOLE – that is, no texture, you can fall in. You can see that subterranean life looks a little odd, with atmospheric colouring and (if I had defined a water table, there would be a high-tide mark also).
It got me thinking that there was a lot of space UNDER the mountain range that was going to waste, so I decided that part of the science activity centre would be under ground.
hollowing out a mountain - to enclose the exhibition hall
…so I set about making walls and floors from an initial entry staircase leading down from a plateau into a hole. It actually felt like I imagine those early Egyptian tomb archaeologists felt as they inched down a discovered stair case towards who knows what.
The scale of the build is striking – a huge entry hall, then it splits into north and south wings, each 2 storey with, I must say, lovely staircases. these wrap around a huge cavernous exhibition hall.
My inspiration? the entry cavern outside the Queensland Museum – one of my favourite places to sit, chill and listen to whale song [yeah, that was where I was going, but the entry cavern is a “space exploration museum” so i will layer it with some old NASA audio recordings I think]
entry cavern, down the stairs through the "hole"
I found some old space junk, added some mood lighting and, voila, instant atmosphere.
north wing, split level
With a little decoration (thinking ventilation and atmospheric recyc, we have a convincing bunker complex with heaps of space to lay out activities.
Exhibition Hall, from the Mezzanine
A truly huge and very flexible space is the Exhibition hall – we can set up stages, trade fairs, displays – a pool or tennis court (there is room for both) in here, and interestingly I do nearly the whole of this build using only 1 type of object – a “wall1.rwx” (why? actually, because I wondered if I could make something interesting with very few different parts).
It’s dimensions beggar imagination – and parts of it are so far way then do not rez all at once – which is funky and possibly problematic, but if needs be I can bisect the space into 2 huge theatre spaces, ditch some mezzanine and still have room for tons of stuff.
Walking/flying around stuff this big is tiresome, so will investigate personal transport I think, maybe some warp/jump pads for punters to move around, I will see how it pans out as the space is deployed. Most of this space is flagged for “alternative renewable energy research” and there is heaps to do, will see what is left over when done.
Greenhouse above to do next … all in all an interesting time
iPost 3.0
… now there is this big eLearning showcasey thing next week for EQ people but I will not be there because I am not, well, really an EQ person (Hi if you are a delegate reading this, I am speaking to you from the past … how weird is that?).
The Learning Place wants to showcase some of the aspects of MyWorld that already exist – a golden opportunity to show some of what has been done already, as a stepping stone to what can be done in the future…
iPost v3.0, step 1 in the tour de-vworld
… so it got me thinking what sort of symbolism is naturally “tourist-focussed”.
I know when I am in a strange place, being a tourist, I head for the big blue “P” signs to park and the big blue “i” signs as they usually mean INFORMATION, so I set about designing an “information post – or iPost for short”. It took 3 goes until I got one that I was relatively happy with, hence iPost3.0. They are made up of 2 parts (w-iPost1.rwx and w-iPost2.rwx, with part 1 being the base that throbs with a red “notice me” beacon, and part 2 the disk with the “i” rotating gently).
Wings3D is a useful mesh sculpting tool, and I am getting good at sculpting custom geometry, and beginning to understand the structure of a rwx file, so eventually I will be able to hack (without breaking) them to add texture, light, shading and other attributes.
DJ gave me a list of itinerary points she wanted to feature, so I set about setting out a trail of iPosts. It became apparent that each iPost would need some form of annotation so the tourists could nav and learn as they were going, without having to wait for a tour guide, so I included with each iPost a notice board with some simple orientation info.
unobtrusive but obvious, such a conundrum
The challenge was to make them visible, but not dominate the areas they sit in – they are, after all merely one way through the worlds. I hope we highlight some of the good ideas and work that has already been put into this world – a beginning in some ways, providing muct potential for young learners.
I used a mixture of teleports (instantaneously “arriving” at the destination when on another world, or where scenery gets in the way) and warps (fast forward travellators for placemarks that are within cooee of each other) and I think the mix works – warps are particularly useful for giving a sense of space, scale, direction and displacement and can be a fun ride.
little known details, cached potential
I discovered an issue that is potentially disorientating – when you teleport to part of a building, you may arrive before the building does, particularly problematic if that location is upstairs – you plummet to ground and then the building arrives around you effectively trapping you. The iPost above is the result of being bounced behind a building with the next jump taking you into it – thereby giving the world a chance to catch up with the traveler – caching the geometry as it were, pre-fetching it before you wind up trapped in it. This all depends on the net connection, bandwidth and so on, not sure i can do much more about that.
I have had a couple of guinea pig cybernauts test it out, it is a circuit – tourists can join it wherever they see an iPost. We can either leave the tourist trail in place after the event, or HIDE the iPosts until they are needed again.
Will it be successful? I have no idea – maybe the punters will tell me. Is there anybody out there?
Up Up and Away … to Sky City
Now this idea occurred to me after a cybernaut (thanks Mitchell) sheepishly took me to a place where he thought other cybernauts had done something naughty – let me explain.
When you clone an object from one that already exists (the first step in Activeworld building), you get to choose the n-s, w-e and the up-down-ness of the newly created clone. Someone had discovered that on the construction planet (Obscura) you could change the up-nicity of an object to 500m or so (waaaay above viewing distance which is typically maxed out at 200m). What makes this neat is they then FLEW up and made a lego raft at that altitude. Far from being naughty, I thought it was brilliant, and an idea well worth expanding.
It got me thinking, that maybe our budding builders need a more realistic challenge (or maybe lego is sooo yesterday man), so came upon an idea for a building challenge.
Welcome Cybernauts to SKY CITY
So I rigged a rusting girder platform, on some “suspensors” some 4oom above our pyramid zone (the lego building zone for noobies), lay down modular flooring, signage and some simple rules and regs, then assembled a collection of components (the lego pieces – shhhh, don’t tell them it is the same thing) they could use to make buildings in a custom “object dock” flying a little above the platform and I think I am on to a good idea.
A high altitude object dock
By giving then carefully chosen objects that fit together seamlessly, and some simple construction instructions, punters clone and place their creations on the expanding platform. They are high enough to have conversation and not flood the ground with it, but the space is sufficiently detached from the main building academy (at least vertically) to be private enough for them to think they are being independent.
humanoid-scaled building
I chose modular scenery, walls etc that were humanoid scale – so when the build rooms and corridors they feel right. I may offer specialist building workshops at altitude – we shall have to wait to gauge the interest but it is certain that we have some interested little people with time on their hands that they are willing to spend in-world, so why not harness some of that creativity.
I also learned something about saved object groups that will be very useful. Once I had made the object bay, complete, I saved that to my hard drive (complete) so I can clone them wherever I want – they maintain their altitude information so I can be on the ground and make one appear some 400m above me almost instantly – pretty neat I think.
Is this going to result in great architecture? I do not know – it will be interesting to find out however. What do you think are the pluses and minuses of this approach – should there be city by-laws, construction codes or is that just complicating things way to much?
POSTSCRIPT:
Some kids just needed encouragement – they are doing wonderful stuff when given a little advice and some personal freedom, I can only be impressed
first buildings go up
Eco feet…
Each journey starts with a single step
So, when visualizing a learning opportunity, I like to see it as a series of “stations” or activities, a journey if you like through the course material that hopefully provides a structured and developmental approach to the unfamiliar, one step at a time.
trail of breadcrumbs
So, we are getting students to investigate their ecological impact on the planet. To do this, they explore an “ecological footprint” – so it seems natural they walk along a previously established path of green footprints.
I like the visual metaphor of the trail of breadcrumbs – it is a universal “follow me” beacon. Students proceed from the rally point to investigate, down a labyrinthal corridor to room 2.3.
I have set up a room for this activity, and had to decide how to lead students in a linear way through a developmental sequence without tying them down so strictly they cannot investigate in an order that also suits their own style. Fortunately I had a lesson plan (thanks Deb) and so sort of used that as the skeleton for the area.
So, just inside the door of the room, we take students through what amounts to a rationale of what we are going to do and why that is a valid thing to do. I want to believe that students will read this but hope that their teachers have also done some of the ground work prior to the in-world experience; seeing this cold would be hard work for younger punters I suspect.
I used a “power point” metaphor here, but presented each slide on a separate screen – an information walk of types – the red foot trail emphasizing the start here and walk to here – I think it is clear.
some formal reference material
We then dive out to some robust reference material – each of these screens spawns a webpage in the in-world browser – one is a reference site on ecological impact that contains a fair bit of reading and some snarly vocab – the other is our glossary from our Wiki (a work in progress) which I think will help de-goddldeygook the references. The aim here is to allow them to become informed about issues and measures – with real classroom intervention this has the potential be a rich experience.
now for some personal calculation
Punters now calculate their personal eco foot print – the site linked here is a neato flash learning object that delivers, via a series of point and click survey questions, the number of hectares their personal ecological footprint measures. They need this information, and it is nice and accessible, the language and visuals guide you in well thought out stages.
go green, care and share
On their journey, they have formed opinions and got ideas on what are ecologically sustainable practices, good green things to do … so we ask them to post a “top tip” to a database-managed collection and then explore other contributions.
Next we ask them to use a little value judgement, and place their own personal eco footprint somewhere on a coloured continua (low impact .. high impact) – this necessitates a world-skill, that of making positioning and describing a new object.
how to recipe
Rather than just presume punters would know how, I thought making the process explicit was a good idea – we have seen some random, clumsy and inexpert spawning of response objects so far, so a little world-skill building is a good idea.
rainbow graph
The visual metaphor of “cold” to “hot” I thought would resonate, and asking them to place it in a non-quantitative way should also get them thinking in comparative ways, at least that is the aim.
We have cybernauts in here next week, guess the proof of the design will be in the successful completion, and abundance quality discussion, idea sharing and (dare I hope) learning.
What do you think?
