Fiberglass skeleton of the custom-made dome
I started to build small-scalle dome with fiberglass pole segments (those used for tents), inspired by some models I've seen made with canes, dome tents and information from Paul Bourke's paper [1]. I also looked at geodesic dome constructions but they seem less portable. My plan is to construct something which weights around 10 kilos in total (very light for a dome) and which could be easily transported and will fit in my studio for testing purposes.
I need the following components:
- Dome (in construction)
- Video Projector (using for now a Mitsubishi LVP-S50, which I got years back in Akihabara).
- 180 degree spherical mirror
- MacbookPro rnuning Blender 2.49

First I purchased a couple of camping tents which provided me with a total of 34 fiberglass segments. I still need another 75, according to my calculations.
The model will have a diameter of 263 cm and a height of 165 cm. Below some of my calculations on an excel marksheet:
