I do need to go back to this last 3D model in Blender once more—if only to measure some dimensions. For visual clarity, I should add them to the images, but I don't feel like learning how to do that, and I really just want to get a rough idea anyway.
On the ground, the base of the trunk is 17' (5m) across. The area inside the trunk is a circular area about 13' (4m) across and 12' (3.5m) to 13' (4m) tall. This will probably get a bit shorter since the roof seems a bit thin, and that's what carries the bulk of the weight.
The first level is about 62' (19m) across, meaning it extends over the ground about 22.5' (7m) out from the trunk. Standing on the first level, the trunk is much narrower at 8.5' (2.5m) across. The second level is about 46.5' (14m) across, and the top branches are about 40.5' (12.5m) across.
The bottom of the first level is about 12' (3.5m) to 16.5' (5m) high, and its walking surface runs from about 13.5' (4m) to 18' (5.5m) off the ground. On the first level, there is about 7' (2m) to 7.5' (2.5m) of headroom to the second level whose walking surface is about 23' (7m) to 28.5' (8.5m) off the ground.
The branches at the top are only about 5' (1.5m) to 6' (2m) above the second level, so I might need to raise them. As it stands now, the top branches are about 31' (9.5m) off the ground with the very tips reaching as high as 35' (11m).
The tl;dr is that the trunk is 17' (5m) across, the whole Temple of Seasons is about 62' (19m) across and about 35' (11m) tall.
For comparison, the last Temple I experienced was the Temple of Whollyness in 2013 which claimed a central pyramid with a base that's 88'x88' (27m x 27m) and 64' (20m) tall with additional work that extends the base to 116'x116' (36m x 36m)—for all intents and purposes about twice as tall and twice as big across. This is similar in scale to 2014's Temple of Grace which was "70+' high, and had a footprint of 80'x80'; it sat in a courtyard approximately 150'x150'" In fact, it seems like this is the approximate size of most of the temples, and the scale is only growing.
I got back to Blender and added a couple passes of leaves. I simply floated them below each of the twigs, expecting up to 4 on each one. On the "sparse" view, I put one leaf on about half the twigs.
It's kind of hard to see the sparse collection, so here's the "man on the branch" view:
And then I went ahead and filled out nearly all the open slots—I think there's about 200 empty with 2,008 filled. Again from the branch-view for comparison-sake:
Finally, I've been enamored of the "far-away" view even though I haven't posted much:
I think this pretty much concludes my work with this particular 3D model. Right now I can see making two models in the future: first is one that will be the basic shell with the mechanics to allow it to be assembled, and how it will collapse; second is a final design that will be a board-by-board construction that should really drive me insane. One change would be to go with 2×3 lumber for the twigs instead of 2x4s. This would make the twigs look, well, more twiggy and allow the leaves to stand out more.
In thinking about the next stage, I'm thinking that the crowning branches might not be worth having—at least not in the thick form they are now. From my first idea of how the Temple would be, I kind of knew how the lower level would be assembled and how it would collapse. Recently I devised a way for the second tier to be added, modelling it after a kind of scissor-jack that would raise it into place. That would also allow it to collapse straight down as the lower-level split outward.
I got back to Blender today and quickly added some twigs to the lower-level branches. I was almost done and it crashed so I had to do it again … faster the second time, so there's good and bad with that. My eyes were going a bit crazy trying to see where to place things as it got quite dense. I think it's too cluttered with branches to permit leaves to hang off the twigs (at least without getting all tangled with one another) but I'll have to wait and put fresh eyes on it another day.
It's getting kind of hard to see, so I have another angle I've been playing with that's a person standing on the lower level:
I'm not thrilled with this result, and having only added 50 twigs, it's not enough to get close to my earlier estimates of the number of leaves for solid coverage. I figure I'll have about 4 spots for leaves on each twig or branch. In these images, there are 268 lower small branches, 50 twigs, and 124 upper small branches for total of 442. With 4 on each one, that's only 1,768 close to the sparse fill with 1,900—although that was an even distribution on a hemisphere and not in a pattern mostly on the outer sides. By not filling in the top, it makes for an odd kind of tree, but one that seems to look okay looking from the ground.
Starting with the idea I had with making canopies—by hanging thinner branches from above rather than supporting from below—I came up with a way to make a 3D test of that idea. I started by making guard-rail posts around the perimeter of the elevated trunks that people walk on. Working upward, many of the posts would have a rope to anchor the bottom of a branch. On the lower elevated level, the tips of the branches would have a rope tied to another branch which would have holes to hang leaves with messages; the upper level would only have the main branches to hang leaves. The tips of all these branches would be anchored from above with ropes to the next level up.
This way, the branches will sway with the wind with a great deal of flexibility. Further, for any that break, the rope or rigid branch can both be replaced on the Playa. If the branches had been rigidly attached from below, flexing of the branches would be difficult to achieve, and they would be prone to permanent breakage.
For now, I only rendered the first set of branches, omitting the forks on the lower elevated level. I also omitted any anchors, simply placing the branches how I would like them to appear.
I decided to try splitting the second-story branches for better coverage. The idea is to use ropes from the first level branches on upward, tangled to tension, to emulate the finer branches that would hold the leaves.
Just to get an idea of what the canopy might look like, I fiddled around with making 4"x6" (100mm x 150mm) rectangular "leaves"—about the size I could expect from using the slats from palettes. I just applied them in a hemispherical dome. I started with a modest number that could be easily realized—some 1,900 leaves.
I thought I'd go a little crazy and see how dense the shadow would get if I pushed it to 11,000 leaves. I would guess this would be a very optimistic goal to achieve, but not complete out of reach.
Looking at a blinking yellow warning light, I got to thinking about how to mark any heavy cabling to secure the Temple during the event. In day, there is less concern as simply adding some ribbon would work. At night I thought to have a LED projection along the length of the cable. Then I figured side-emitting fiber-optic cords would be nice, lit green for optimal visibility. This led me to spiral the fiber-optics, and it would kind of look like a vine climbing, perhaps like an electronic morning glory.
On the technical side, I figured 1 watt of LED light would be plenty, but I'd like to have a redundant pair on each cable. This would mean about 10 watt-hours each per night which could be recharged by a 2W solar cell. But for the sake of using 10 watt-hours for, say, 8 nights, that's just 80 watt-hours. Quality alkaline D-cell batteries are typically 10 amp-hours at 1.5V or about 15 watt-hours each, so it would take a minimum of 6 batteries to hit that mark. A simple resistor circuit could drop a series-parallel pack wired for 4.5 volts to the necessary 3.5 volts at 280mA[1. Estimated from Luxeon Star-III specification sheet, rated for 700mA @ 3.5V = 2.5W]. The current would draw symmetrically (theoretically) from each chain of 4.5V, so the runtime on the battery would be a total of 10AH / 0.14A = 71 hours. (The discrepancy from 90 hours is because it's 280mA at 4.5V which is more like 1.3W. What will happen, though, is the light will get slightly dimmer and the battery last longer. The resistor is fixed at 1V / 280mA = 3.6Ω, so when the battery has dropped to 4V, the resistor drop is only 0.5V, and so the current is 0.5V / 3.6Ω = 140mA.)
I guess that got way too technical too fast. Oh well.
After laboring over Blender for some time, I finally created a model of the Temple. It's a bit rough and the wood grain appearance is way over-scale, but it's at least a start. I'm also trying to figure out the best way to make it look like it's on the Playa … at least a little.
I decided I needed to learn a 3D rending software. I found Blender which is Open-Souce, and, hence, free. I read a bunch about the user interface and found it quite daunting because it was unlike any software I had used. Well, it was like all the software I had ever used, just mashed-up in a way I hadn't encountered yet. In 2 hours I had made it through most of the tutorial to make a gingerbread man and had a better understanding of how it worked. I was rather elated at the progress I had made. I recalled what it was like to learn something new and get good results—the kind of thing that fired my obsession with computers in my teen years.
