06:54 | <~Vorntastic> | Ok so. One super weird advantage of a bezier is that you can generate the vector and then just dot it against the control points vector to get the result. Even cooler you can do this for a bezier surface where the control points are a matrix: multiply the matrix by the u vector and then dot the result with the v vector |
06:56 | <~Vorntastic> | Downside with that being numerical stability problems |
06:58 | <~Vorntastic> | Which technically you can beat by doing a *lot* of matrix multiplications, one for each step of de Casteljau |
07:00 | <~Vorntastic> | Question I have though, since the data I can get is in fact Hermite surfaces, is there a similar operation |
07:04 | <@abudhabi> | Droidcam works! |
07:05 | <@abudhabi> | Just tried it over wifi. Pretty sweet. I don't have to quit monitoring my chickens. :D |
07:08 | <~Vorntastic> | It feels like the answer should be yes but I am uncertain how to seek it out yet. |
07:08 | <@abudhabi> | Some limitations are that it displays horizontal, and only uses the front cam. |
07:08 | <~Vorntastic> | Literal chickens? |
07:09 | <@abudhabi> | Literal chickens. 42 are in the pen, 3 still in the incubator after a bit of assisted delivery. |
07:10 | <~Vorntastic> | Sweet |
07:10 | <@abudhabi> | No, wait, I'm off by one. 48 eggs survived to late stage, two confirmed dead, and three in the incubator, so 46 total, 43 in the pen. |
07:10 | <~Vorntastic> | Fencepost errors in the real world? |
07:11 | <@abudhabi> | Heh. |
07:11 | <@abudhabi> | I've set up a youtube-based livestream using my old laptop to not have to check up on them personally. I can just go to the stream and check how they're doing. |
07:12 | <@abudhabi> | Whereas I still need a cam for standups, as my work laptop doesn't come with an integrated one. |
07:41 | <~Vorntastic> | Single dimensional Hermite can be converted into single dimensional bezier using a single matrix |
07:41 | <~Vorntastic> | Okay that helps |
07:43 | <&McMartin> | You have traveled far beyond my ken |
07:50 | <~Vorntastic> | I don't know many people in this realm |
07:50 | <&McMartin> | Is this related to the things you were shading? |
07:53 | <~Vorntastic> | Yes |
