@xot that's how some DMA works. DMA does not always work like this on every system. Famously, the Sega Genesis featured something called Blast Processing, which is the ability for the 68000 and VDP to access the same bus at the exact same time during DMA, so you can write directly to the scanline during active scan to drive it at 8bpp, despite the Genesis only formally accepting 6bpp color.

@xot oh I very much consider myself a baby when it comes to computers. The ocean is too deep to ever reach the bottom lol.

On the Amiga, the whole system was built around simultaneous access, so DMA is split between time frames, even and odd. On even frames, the 68000 has bus access, on odd frames, the agnus chip has access. So they get around the bus access problem, kind of like preemptive multitasking in general.

@TomF @xot the curse of planar graphics in general, 1 pixel 6 pokes lol.

GabeMoralesVR,
@GabeMoralesVR@mastodon.gamedev.place avatar

@TomF @xot they were pretty much the norm back then, no? CGA, apple IIgs, Even in the console space, stuff like the sega master system and SNES used planar graphics too. Chunky graphics are obviously superior but it doesn't seem like until around 1990-ish that chunky took over, likely owing to ram finally falling enough in price.

I do like the cheap transparency tricks you can do with planar graphics tho.

@TomF @xot wasn't the dream of a direct color chunky fullscreen framebuffer essentially the entire reason the atari jaguar and sega 32X exist? lol

GabeMoralesVR,
@GabeMoralesVR@mastodon.gamedev.place avatar

@TomF @xot @TomF @xot AGA was still bitplaned, the CD32 had a chip called Akiko that was hardware chunky2planar conversion but it was slow.

The Sega Genesis is 4bpp byte packed, so 2 pixels per byte. Similarly, in index mode, the 32X processes at word length, so 2 bytes/16 bit as a time. So even though the framebuffer is 8bpp, it's read 2 pixels at a time, with a 1 pixel horizontal shift register for smooth scrolling. In both cases, you have to treat each chunky pack as 2 pixels.

@TomF @xot I actually love the Jaguar, I know the system has problems and it was severely cash starved, but it's like this fascinating train wreck that I honestly adore. I have a skunk board, the jaguar is a tech fetishist dream, so much parallel stuff happening. I unironically love the system, I think those games which used the low color mode in conjunction with heavy gouraud shading still look incredible, like Zero Five and obviously Tempest 2000.

The good news: The #Atari STE don't just have #blitter library functions, it has separate blitter hardware!

The bad news: using the blitter blocks the #68000 until blitting is done, making the hardware act as though it was a software routine in the end.

The Leaving Rust Gamedev article resonates with most of the frustrations I've had working on the internals of Tangerine (C++) since I converted it from being largely single threaded spaghetti to aggressively concurrent spaghetti, and that's making me think maybe I'd have a better time if I picked a different language for the hot paths, because necessary non-compulsory refactoring also kills iteration time.

I just don't know what though, because nothing ever seems to fit the bill of what I need.

@Doomed_Daniel @adam that's part of the point. Police originally walked beats and interacted with communities. Slowly but surely they got away from that, first not interacting with the streets except by motor vehicle, to eventually not even being on the streets at all. Every step takes them farther and farther away from being personable, local, identifiable people.

I HATE #Onions so incredibly fucking much, jfc. The only food item that completely ruins a meal for me. I cannot stand them, they make me gag. I can't say enough how much I can't stand them. It's not even enough to "pick them off" because I can still taste the juice on whatever they were on.

In other news, thanks whataburger, for mistaking "no onions" with "extra extra extra onions" on my burger. Cool waste of $10.

@shekinahcancook facebook buying oculus in particular was one of the biggest fucking slaps in the face. Oculus was created by literal donations from fans, and the vast majority of their tech was given to them for free from valve under the guise that they were creating a new open standard.

GabeMoralesVR,
@GabeMoralesVR@mastodon.gamedev.place avatar

@shekinahcancook The story about oculus being acquired, and the coup they tried to pull to steal Alan Yate's team away from Valve, is fucking wild, but it'll probably never be told in public spaces.

The single most wild part of the entire story? When Palmer Luckey pitched Oculus to Zuckerberg, he didn't even show him their tech. He gave them a demo of VALVE'S VR Room, claiming it was theirs. Zuck literally thought he'd bought valve's VR team when he bought oculus.

GabeMoralesVR,
@GabeMoralesVR@mastodon.gamedev.place avatar

@shekinahcancook an actual photo of Zuck getting the VR pitch. The equipment he is using is Valve's, not Oculus', and the room he's in is literally called "The Valve Room." Wild, wild shit.

GabeMoralesVR,
@GabeMoralesVR@mastodon.gamedev.place avatar

@shekinahcancook Once Zuck realized after he had bought Oculus that he didn't have access to the very demo which sold him the tech, he tried to buy valve's VR team, but alan yates said fuck no and oculus/facebook stopped all cooperation with valve. THIS is why Oculus shifted from PC VR.

@cwgrody @nba plus there's also the history of refs fixing playoff games. An example that was cited in court was Houston vs Dallas 2005, when Tim Donoughy was instructed to intentionally call phantom fouls on Yao Ming.

I wonder if anybody tried to use FXAA before doing display mapping BUT by still applying and reverting a curve ? 🤔

Aka:
1 - Switch from HDR to SDR
2 - Apply FXAA
3 - Switch back from SDR to HDR
4 - Apply regular post-process stuff
