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.
