Scalarisation and wave intrinsics (to allow intra-warp direct communication) is what all cool kids seem to do nowadays, here's a list of resources on the topic.
Wave Programming in D3D12 and Vulkan …82yhj72224m8j.wpengine.netdna-cdn.com/wp-content/upl…
.@MichalDrobot's "Improved Culling for Tiled and Clustered Rendering in COD:IW" Siggraph talk touches upon the subject as well: advances.realtimerendering.com/s2017/2017_Sig…
Also, it is definitely worth reading the "Introduction to scalarization" blog post series flashypixels.wordpress.com/2018/11/10/int… by @FCifaCiar
Cross-Lane Operations on GCN: gpuopen.com/amd-gcn-assemb… and also gpuopen.com/gcn-shader-ext…
Shader Intrinsics supported by NVidia developer.nvidia.com/reading-betwee… and developer.nvidia.com/unlocking-gpu-…
Wave Intrinsics supported by the DirectX Shader Compiler (SM6.0) github.com/Microsoft/Dire…
Fast uniform load with wave ops by @SebAaltonen gist.github.com/sebbbi/ba44153…
You can try SM6.0 code compiling with DXC online with Shader Playground by @_tim_jones_: shader-playground.timjones.io.

Someone at work asked me today where do I find all those presentations about graphics techniques and made me realise that it might not be so common knowledge to people just starting gfx programming. Thread of links.
Siggraph's Advances in Realtime Rendering is a invaluable resource for cutting edge rendering techniques advances.realtimerendering.com
Same with Open Problems in real time rendering course, although unfortunately it did not run this year openproblems.realtimerendering.com

Here's a short thread about how this ridiculous @theJagmeetSingh controversy exemplifies the reasons why I (and others) increasingly tune out the daily Canadian political news cycle ...
globalnews.ca/news/4847515/j…
The story here is that @theJagmeetSingh was too busy campaigning for a by-election (which he's gonna lose, but never mind that for now) to get up to speed on an asinine comment about white supremacy from the Chinese ambassador. …
Embarrassing? Sure. But it isn't one THOUSANDTH as bad as Singh telling @CBCTerry, in 2017, that "I don't know who's responsible" for the downing of Air India Flight 182—the worst terror attack in Cdn history...The equiv of a U.S. prez candidate saying he didn't know who did 9/11

In light of the #ONPC resolution stating that gender theory is "unscientific," here are a list of resources by medical professionals stating that sex and gender are distinct, and that gender has social aspects. #onpoli #TransRightsAreHumanRights #TransAwarenessWeek
I will also include excerpts from papers showing the link between accepting people's gender and reducing suicide among trans folks. @TGranicAllen's policy will materially contribute to the deaths of transgender people. Please feel free to share this with your MPP.

[MASCOT] The MASCOT separation operation has begun! Preparations for the descent of Hayabusa2 towards asteroid Ryugu began in September 30, but today (October 2) the spacecraft will begin to descend. #asteroidlanding
[MASCOT] October 2 at 12:14 JST: The spacecraft was confirmed to have started the descent from the home position (altitude of about 20km) as planned. #AsteroidLanding
[MASCOT] During the MASCOT deployment operation, images taken for navigation with the Optical Navigation Camera - Wide angle (ONC-W1) will be replayed in real time. Come and see our gallery! #asteroidlanding hayabusa2.jaxa.jp/en/galleries/o…

Here are some real ideas to fix the #immigration system.

1. Get rid of the 3 and 10 year bars and replace with a fine.
2. Put more asylum officers near the border.
3. Create a market-based cap for employment-based immigration.
4. Create an entrepreneurial startup visa.
5. Create a path to a green card for E-2 investors. Include any children brought here before age 21.
6. Let's really make a 10 year law: provisional green cards.
7. Direct DHS to allow people to take the steps to correct their immigration status.
8. Penalties besides deportation.
9. Put money and resources into fraud detection.
10. Expand guest worker programs to allow people to go back and forth.
11. Invest in antigang resources.
12. Centralized U visa databases.
13. Tax incentives for microbusiness in high unemployment areas.
14. State biz incubators.

Let's write a tiled forward renderer! First step is to cut the screen up into tiles.
...and generate a tile index that we can use to access our array of per-tile data.
It fits in a tweet!
uint GetFragmentTileIndex()
{
vec2 v = floor(gl_FragCoord.xy / 32.0);
return uint(v.y * 40.0 + v.x);
}
