| mircea_popescu: | works! | [08:38] |
| diana_coman: | in other unexpecteds, apparently I'm falling in love with Grassmann algebra; and ofc none of all the "graphics" courses ever as much as mentioned it, idiots. | [09:32] |
| mircea_popescu: | ha! | [10:26] |
| mircea_popescu: | but yes, a large part [of this rally] is precisely that given the shocking narrowness of domain, "peculiar notation" such as a particular representation aka algebra may even be ~reuired~ to even start making sense | [10:27] |
| mircea_popescu: | in any case exterior algebra a fine candidate for looking at | [10:28] |
| mircea_popescu: | hard to avoid the fact that pretty much everything carring a premium in computer graphics is in fact most directly accessible via diff geometry, if regarded as differential forms. | [10:30] |
| mircea_popescu: | those "things you wish to see", whatever common name they carry, "the coolness of that swaying braid" | [10:30] |
| diana_coman: | it gives one not only neat ways to go up the number of dimensions but also back down; you get to define "geometry" and *also* the absence of geometry, it's beautiful. | [10:32] |
| diana_coman: | not that I expect it's in much use though, lol. | [10:32] |
| mircea_popescu: | it's not directly evident to me why it can't be. | [10:33] |
| diana_coman: | it's not that it can not; it's just that it isn't; and the guy's work was apparently ignored during his lifetime too, for added wtf. | [10:34] |
| mircea_popescu: | he was actually a very interesting character | [10:34] |
| mircea_popescu: | i know of him because he's taught as a linguist of all things. ye 1800s german folklore-language school | [10:34] |
| diana_coman: | ha! I had no idea. | [10:35] |
| diana_coman: | now ofc I'll still have to get back to the practical and investigate all those blender shmlenders. | [10:36] |
| mircea_popescu: | yeah. | [10:37] |
