Do you have any interesting reads about geometric algebra being the "new" thing?
- theoh 11y agoNot the parent poster, but I have some experience of geometric algebra being promoted as a superior language for geometric computing. This started for me in the first year of university with a tutor who was keen to introduce bivectors (a GA concept) though officially they weren't on the syllabus. (Bivectors can represent 3D angular momentum in a slightly more useful way than straight vectors.) David Hestenes was presented as a bit of a hero, the pioneer of GA for physics. It didn't stick for me. At Siggraph 2001 there were for the first time a couple of "GA for computer graphics" presentations given by Leo Dorst and Steve Mann. They were promoting GA as "the way" for doing geometric computations on computer. Dorst is an interesting and pleasant speaker and the apparent brashness of the "one true framework for geometric computing" claim didn't really colour his delivery of the presentation. Again, for me it just didn't stick, though the idea of a breakthrough in the design of geometric mathematics, with strong historical roots in the 19th C, was appealing. Since then the GA bandwagon has rolled gently on but I haven't seen any killer apps produced so far. http://www.geometricalgebra.net/ http://www.geometricalgebra.net/ http://www.cgl.uwaterloo.ca/smann/GABLE/SIGGRAPH01/ http://www.cgl.uwaterloo.ca/smann/GABLE/SIGGRAPH01/
