I'm trying to imagine who was upset enough at this particular staging of Into The Woods that they demanded this disclaimer run in the credits when it was filmed. pic.twitter.com/l7xaZyKFzW

As far as I know, Unreal 1 had the first real-time implementation of volumetric dog. I used a formula table in an 1800's math book(!) to calculate a line integral on a 1/r^2 light falloff function using an arctan. ~200 cycles on Pentium, but fast enough on a 16x16 grid.

@s_ridenour We send them as one big vertex buffer only when forced to draw (on present, render target change, or a texture in the queue updating), which eliminates a million little pipeline stalls and state changes. We don’t need a matrix per-sprite, just vertex coords, pretransformed. Tweeted 18 Sep 18 in reply to Sean Ridenour via Twitter for iPhone

@s_ridenour Yep, it handles batching at the top level and hands a queue of rendering commands to the reworked rendering backends. Tweeted 18 Sep 18 in reply to Sean Ridenour via Twitter for iPhone

Moved this to the higher level now. On this MacBook with 20,000 draw calls: SDL 2.0.8 OpenGL: 40fps SDL 2.0.8 Metal: 90fps My new batching code OpenGL: 200fps And that's using immediate mode OpenGL! Imagine what Metal is going to do when converted! :) Tweeted 18 Sep 18 in reply to icculus via Twitter Web Client

If you want to know how terrified Linux kernel contributors are, in the 18 hours following the announcement that the project leader is stepping down indefinitely only 7 people replied publicly on the LKML lkml.org/lkml/2018/9/16… Tweeted 17 Sep 18 via Twitter Web Client

@ivucica We apply patches to revision control, but we don’t intend to do another release. (Although we really _should_ do a 1.2.16 with all the accumulated patches...) Tweeted 16 Sep 18 in reply to Ivan Vučica via Twitter for iPhone

@ComputerMouth It chooses the runtime by default, but recently Steam has been favoring system libs, moving it from Complete Framework to Fills In What’s Missing. Tweeted 15 Sep 18 in reply to ben older via Twitter for iPhone

Fwiw, my decades-long strategy has been to keep my résumé in plain text to drive away recruiters that ask "can you send this in Word format?" icculus.org/resume twitter.com/Kaptain_Kaos/s… Tweeted 14 Sep 18 via Twitter Web Client

Minor clarifications to gamingonlinux.com/articles/forsa… ... Steam (not Forsaken) currently favors your system installed SDL over the Steam Runtime, Ubuntu uses the Debian SDL2 package, and all the appropriate parties are on the case to correct the problems.
