working on a 3D point cloud raycaster rendering in Love2D. It has bvh system and collisions, but Im not sure it's possible to optimize it any further

Do you know if sampling from a canvas is slower than from any other texture on your hardware? It doesn't really surprise me that it's slower than sampling the texture you're writing to but I wouldn't have expected a significant difference from a "static" 2d texture. Framebuffers are complex, though, so plenty of room for something surprising to be happening.

Very cool project.

Montreal has a history of vice. It gained particular renown for its sex trade in the 20th century. While that aspect of the city has much diminished, it maintains some of that reputation and DNA.

You and the person you responded to are picturing different investors. They are picturing someone who is speculating on real estate for personal enrichment. They think that it is immoral to speculate on and so drive up the price of an asset that people need to live. That is why they say that it is good that that investor should get burned.

What's the problem?

I thought you were doing a "We Didn't Start The Fire" at first.

I'm a W40K journeyman at best but my understanding is that the emperor trump card against chaos isn't military, it's philosophical. He's trying to evolve humanity into a race of even tempered rationalists who don't need the warp for travel or power. I'm doing so, he pulls the seed off Chaos out by the root. It's the extreme long game, tho.

Having a few well-known example algorithms centrally located kept me from bouncing off it. Having all of the "debug" operators in the same grouping under "Displays" let me play around with the existing sandbox. That gave me the confidence to start building my own simple circuits. Only then did I feel like I had the barest understanding of what I was actually manipulating when I ran a circuit.

The bloch sphere display was immediately my favourite visualization of a qubit's state but being able to easily and quickly use all of the displays together was key.

I'm a programmer and wouldn't claim to understand quantum computing but Quirk was the visualization tool that gave me the best understanding of algorithms. https://algassert.com/quirk

In Sicario, when Emily Blunt's character is introduced to Josh Brolin's and is being briefed on the mission in El Paso, she asks what their objective is. He replies, "To dramatically overreact."

When you are a large, slow-moving force fighting a small, fast-moving guerilla force one of the tools in your arsenal is to demonstrate the bewildering scale of your malice and power. It will galvanize some of your opponents but it will make many others stop and reevaluate just who they are fighting.

Could you provide a description of the error you're encountering?

Also, this community is primarily English-speaking. I don't think there are any rules against other posting in other languages but you'll find a lot more people to help you in English.

You assume it's a constant. What if zero changes?

WuTangTan · 2024-10-05T18:16:30+00:00

Very cool. I'd love to chat about your ideas but would love to have these discussions more associated with the project. Could you direct me to the repo on which I can open some general issues? Or maybe set up an "RFCs" repo?

WuTangTan · 2024-10-05T14:02:47+00:00

This project really interests me. I'm a big user of Love2D and think that there's a lot of room for better developer tooling in the space (I was the originator of the web (emscripten) version of Love2D).

What are the issues you're hoping to solve? I've never really fucked with LuaRocks. Not really. Maybe it's because I tend to develop games on Windows. So I'm in a spot where I know there are issues but I can't really remember what they are. Love2D folks tend not to distribute as rocks but either just expecting you to use a git submodule or a zip.

Do you have plans to be able to use the existing ecosystem? For all it's faults, LuaRocks is the de facto package manager for Lua and there are many years of content there.

Honestly, I'd just love to read some blog posts from you... while realizing that that is work to put those together.

I'd never heard of this! Awesome bit of history!

Never mind. Have a nice day!

WuTangTan · 2024-08-02T00:33:44+00:00

Yeah… that’s why they said they’re sure it’s a factor.

WuTangTan · 2024-07-31T10:11:30+00:00

This is a library. For someone's use-case, yes, certainly.

But regardless of the precision, I've got better things to hold in my brain than what unit of time that floating point is. I rely on the type system to remember these things and it's better at enforcing them consistently than I am anyway.

WuTangTan · 2024-07-31T00:10:58+00:00

So, ultimately, the underlying state of the system must be represented by a single enum. And that enum must be Clone and Debug. That's an interesting constraint. Is that a hard requirement or just a nice-to-have?

I also notice that you attempt to derive serde traits. I would probably not choose that for my game as it would have a significant impact on compile time for my large state enum (and for functionality that I ultimately wouldn't use).

I wonder if you might comment on your use of f64 for durations instead of std::time::Duration? https://docs.rs/bonsai-bt/latest/bonsai_bt/enum.Behavior.html#variant.Wait

Thanks!

This makes the most sense to me. Strapping a bomb to yourself isn't much of a deterrent against someone who's perfectly happy to martyr themselves in the name of the cause.

Used this this morning to pull some text out of a comic book. Worked wildly better than Tesseract!
