Temple Collapse Simulation

I hadn't touched Blender in months but I got back to it and figured out how to link objects with hinges. I took the original design and split off individual segments then connected them together how I wanted. The simulation isn't great since it's a rigid-body simulation so the parts act like they're infinitely hard rather than deforming and breaking under stress. I did set up most of the hinges to break under a high load as I would expect to happen in reality. Unfortunately the combination of rigid objects and breakable hinges means many of the pieces just pop off immediately.

In any case, the point is to demonstrate the way the Temple would collapse during the burn. Once the safety supports are removed for the burn, the first level would be held up by one or more thick hemp ropes wrapped around the main central posts. When the fire weakened the rope enough, it would break and unlace through the support, staying in the channel designed for this purpose. That would release all the sides at the same time and cause the whole Temple to collapse at once, giving it a definitive end.

The next step, I think, is to rework this backwards to show how I intend the first level to be assembled—basically in reverse of collapse. I think if I do that, I can get Blender to fit the pieces together without being under exploding pressure.

Second Small Model

I was reinvigorated to work on the temple again. I want to make a structure that is so appealing (visually, emotionally, and otherwise) that nobody will want to burn it. And I want to integrate the community so they are fully invested in the project.

I drew some more sketches, trying to focus on the appearance of the end product rather than being fixated on the ability to construct it. I started in on making a model again. I took a couple 2×4's and hot-glued them together for a "trunk". Then I needed something to make branches. I was looking for inspiration outdoors when I decided to use some sticks from my magnolia tree. I cut them and glued them on then added bamboo skewers as branches and small scraps of paper as the "leaves". For some kind of scale, I added Vince.

I basically built 1/4 of the tree and took some test photos against a colored backdrop. I had four photos, each with the model rotated 90 degrees—all set up with the same camera settings on a tripod. Then I pulled it into Gimp, did a rough removal of the colored background and composited the four rotations on top of one another to create a pseudo-representation of a full model. I added a photo of the Playa from Vittorio Carli's artinterviews.com to make it look like it was at Burning Man.

Burning the Model

Tuesday got rained out so I went to Antoni's in the afternoon with some stuff. He had built most of the 1:6 (e.g. "Barbie scale") model and we finished up the remaining bits.

It looked really good although he didn't have time to finish putting a skin on the third quadrant, and didn't even assemble the fourth. We put together the fourth and tried burning it. It went okay although it collapsed organically like a structure. I had tied it together with rope but the quadrants weren't weighted enough to topple and didn't fall over when the rope burned through.

First Temple Model

I have been working on some scale drawings in 2-dimensional CAD software and came up with a way to build the main branches. There would be four branches—one for each compass direction—and all of them would be similarly constructed. Alone, each would fall outward, so they would need to be tied to the mirrored pair to balance it.

The branches would be built in segments that could be prefabricated and brought to the Playa for final assembly. The assembly could be done by hand, using only simple pulleys and winches to lift the branches. By working in mirrored teams, the branches would counterbalance one another. As they are winched off the ground, the next segment could be attached, continuing in this way until they are fully hoisted into position.
