I’m not sure carrying wavelength or spectral info changes anything with respect to order of transparency. It seems like OIT is kind of a misnomer when people are talking about deferred compositing. Storing data and sorting later isn’t exact

> RGB assumes all light sources consist of three RGB lights Another way to say this is that conventional 3 channel renderers pre-integrate the spectrum of lights down to 3-channel colors. They don’t necessarily assume three lights, but

You’re partly asking questions about APIs rather than questions about GPUs. It might help to identify any specific goals you have and any specific tools or APIs you intend to use. In general, you can use just about any data format you want.

You’re asking a strange question that doesn’t get at why shaders exist. If you actually want to understand them, you must understand the bigger picture of how they fit into the pipeline, and what they are designed to do. You can do line dra

> Raymarching is a raytracing technique… Did you mean ‘raymarching is a technique…’? Otherwise you’re somewhat contradicting the first sentence, and also ray marching and ray tracing are two different techniques, which is what you’re try

Figuring out if a pixel is within a shape, or is on the A-B intersection line, is part of the rasterizing step, not the shading. At least in the parent’s analogy. There are quite a few different ways to draw a red line between two points. A

At least Vulkan runs on Windows, that certainly makes it more cross-platform than DirectX. According to Google, some VNCs on Linux don’t support Vulkan, but I don’t think that’s a fair reason to suggest Vulkan doesn’t run on Linux in genera

I think what you’re describing is the difference between raster and vector graphics, and doesn’t reflect on shaders directly. It always depends on your goals, of course. The goal of drawing with a pen is to draw outlines, but the goal behin

by dahart 11mo ago
Rasterizing and shading are two separate stages. You don’t need to know pixel position when shading. You can wire up the pixel coordinates, if you want, and they are often nearby, but it’s not necessary. This gets even more clear when you

Just absolutely beautiful execution, and this is a metric ton of work. I love the diagrams and the scrollbar and the style in general. There are a few tiny conceptual things that maybe could smooth out and improve the story. I’m a fan of ke

Sure the claim that an artifact like a painting is valuable because it’s rare & famous is somewhat self-reinforcing, I agree. I also think it’s fair to call it circular in the sense that people investing and making a profit when they re

by dahart 11mo ago
Oh I agree with you there 100%. That’s a different issue than having no proof at all, or no claim or story, right?
463.
by dahart 11mo ago
Hehe, I like it. Yeah that’s a valid, if funny and tautological way to summarize it. I am arguing that the monetary value comes from the story attached something that’s unique, historical, famous, etc. The artifact itself didn’t change valu

Is it crazy? Clearly the value is the proof itself, not the item, right? Certainly a genuine da Vinci is an investment you can very likely recoup and make a profit on. If I could buy one that’s proven, for a million, and I had a million sit

Sure, but that’s not how IQ tests are designed, nor what IQ is. Most people understand the concept of intelligence, regardless of their IQ score. The methodology of IQ testing doesn’t require having a question that only the “smartest” perso

by dahart 11mo ago
Hehehe you got the first part right. Human running requires intelligence, I don’t know how to separate those or evaluate their complexity, and I bet you don’t either. So do you know anything about how IQ tests work? You know they’re timed,

Oh yeah, knowing the difference between the runtime API and driver API is definitely an issue, and there is common confusion around that. But that’s not an overloaded word problem, right? I wasn’t trying to say there’s no confusion, and I d

This article has good info, but is the overloading premise slightly contrived? Maybe I don’t talk to enough CUDA beginners. I work with CUDA a lot but I’m not exactly a CUDA expert, and from my perspective, in practice there are default ass

Why would it say anything? The 100 meter dash wasn’t designed by the fastest 100 meter runner, but it’s still perfectly capable of identifying a winner.

Oh definitely, I agree, woodcut and digital art and photos, for example, are all wildly different media. I’d expect a woodcut to cost more than a photo, all else being equal, because it’s more physical - both making the plate, and setting u

That’s an interesting concept. Can you talk more about how you imagine that affecting the market? My first reaction is that it wouldn’t solve the value problem at all. Yes you can charge more over time, and in practice it would actually lim

Is the full-sun photo edited to remove the paramotor? I just realized it was in the video shot - the head-down dive “tracking” position of the skydiver in the video happens only a few frames after jumping, only for a few frames, and after t

There’s a video of the jump in the article. You can kinda see the pilot in the paramotor flying away, as the jumper leaves.

Might be worth starting with a baseline where there’s no collision, only advection, and assume higher than 1fps just because this gives higher particles per second but still fits in 24GB? I wouldn’t be too surprised if you can advection 100
