Animation pose reuse

@aras See that weird head shape you get on the white dog?

That's what happens when you try to map a pose to a different rig without proper retargeting

@aras yeah that tracks

No need to fear, the optimizing compiler is here:

mov r8d, 1
test r8, r8
jne .LBB1_2

@pervognsen it's defensive optimizing

@pervognsen The FE changes don't sound minor to me.

I should probably invert my normal research approach for fast algorithms from.

  1. I search the internet for information.
  2. I read @rygorous' blog.

This time it's for fast blurs.

@dougbinks Yup, you're right! Will fix!

so what's his punishment? i expect it to be tough considering in the US you can get 1000 years of jailtime for littering or smth

rygorous,
@rygorous@mastodon.gamedev.place avatar

@aeva @lritter yeah, never forget, owning like $40 worth of weed can get you jail time if you're black, but if you're white and/or a corporation, laundering over $860 million of drug money is a $1200 million fine (if you're caught)

@breakin @aeva @lritter In practical terms, I don't expect this to have much if any immediate consequences, because

  1. of course they'll be going for an appeal, and it's going to be a long time for that dust to settle
  2. election-wise, things being as they are, I find it hard to imagine a significant chunk of the population thinking "well I was gonna vote for him but now that he's been convicted in a jury trial I've changed my mind"

I stopped paying attention to process nodes around 12 nm but I just noticed Arm Cortex X925 is advertised as designed for a 3 nm process. I'm assuming this has even less to do with lambda than it once did?

rygorous,
@rygorous@mastodon.gamedev.place avatar

@pervognsen Yes, absolutely nothing.

As per IRDS (2021), expected feature sizes for "3nm" generation processes are ~48nm gate pitch, ~24nm metal pitch.

@pervognsen This talk is now 11+ years old https://youtu.be/_bhEDQzNQ-c?si=He4dpsBsOCo3330U&t=961 and the editing is terrible but it answered a lot of questions for me about why even SEM images of circuits look very different for newer designs than older ones

I've got a (probably simple) graphics programming-related question:
Is it correct that the only useful values for GL_TEXTURE_MAX_ANISOTROPY_EXT are 2, 4, 8 and 16 (and maybe 1 for "don't use anisotropic filtering")?

At least as far as I can remember I've never seen other values configurable in games; however, for some reason, GL_TEXTURE_MAX_ANISOTROPY_EXT is used with floats (glTexParameterf()), and the spec only says "float greater or equal to 1.0"

rygorous,
@rygorous@mastodon.gamedev.place avatar

@pervognsen @Doomed_Daniel no I'm pretty sure it does support npot2 values, it's just that the limits are usually picked as pow2s. IIRC the actual sample count is just any integer. (but it is ints.)

rygorous,
@rygorous@mastodon.gamedev.place avatar

@zeux @pervognsen @Doomed_Daniel For the one HW where I do know the exact details (the souped-up version of Intel Gen samplers that ended up in LRB1) the way the samplers work internally is that everything other than point filtering is internally sequenced into multiple "bilinear" taps which complete at a rate of (at most) one per cycle and can add into an accumulator over multiple cycles, which is how all the more complex filtering modes work.

When a beverage proclaims "naturally & artificially flavored" on its label in bold letters you know they're not hiding anything. Or maybe they're trying to draw attention away from the supernatural flavoring.

rygorous,
@rygorous@mastodon.gamedev.place avatar

@pervognsen can't overemphasize how relieved I am that this is, evidently, genuine!

can you imagine if it was an imitation blue soda instead

@koos303 @pervognsen just don't let yourself get scammed by the contradiction in terms that is zero-calorie "energy drinks"
