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
08:06
<~Vorntastic>
Let's see

<~Vorntastic>
Yeeeees. Okay!

Huh. A lot of this is much clearer now, including why we use the Bulge Parameter
