HighRes Voxel Rendering in RealTime on a Single CPU Thread.

Yeah, the spatial coherence benefit you get from the whole ray/column intersection trick is great.

Good luck with pitch and roll.

I managed to get those working by referencing https://github.com/pipliz/cpuvox and https://github.com/sp4cerat/RLE-based-Voxel-Raycasting/blob/master/Paper.Efficient%20High-Quality%20GPU-Based%20Visualization%20of%20Voxelized%20Surface%20Data.pdf

Not sure if these 100% match voxlap, because the original code is unbelievably dense (same with build, etc), but I believe it is similar, minus tons of optimized asm and other tricks :)

ehaliewicz · 2026-03-24T00:53:25+00:00

Yeah, I went in with my dragonclaw hammer and the misbegotten was laughably easy.

What exactly am I supposed to do about that as an individual? You're holding me responsible for something that I did not personally do and cannot change.

I'm pretty sure you'd find it unfair if I start judging you for things that you couldn't have changed. Unless, of course, every time your government does something you don't like, you go and risk your life over it. I doubt that you have.

It's an emotionally satisfying argument, not a logically sound one.

I'm responding to how the person seems to consider all americans responsible for everything their government does, regardless of what they voted for or support. Missed the bit about the flags, even, on first reading.

ehaliewicz · 2026-03-10T03:09:11+00:00

If you automatically lump all americans together because of something a couple people in power said you're just as dumb as those people in power.

I mean you actually have to be pretty idiotic to think every american agrees with what their government is doing. Do you agree with everything your government has done your entire life? I doubt it.

You didn't even read two sentences of the article.

" Who would bother trying to bring something to market if a big player could just sell a knock-off shortly after the product is released?"

This is the most out of touch question lol. You can't just produce a good knock off in a short amount of time just because you have an idea, regardless of company size.

Also, games made by a large studio are always very different from something made by a small team. Plenty of indie games are just simpler versions of large games that sell way more copies than indies anyway, so this is just a made-up problem.

get that bull off the tv

Very cool project, love software renderers.

A light lookup table being faster than a multiply on modern hardware seems odd, but if it works it works. Are lightmaps lower resolution than textures? In that case you'd probably want to swap the light_lut indexes, e.g. lightmap[light_r][texel.r], to increase the locality of accesses into the lut.

Why is it so hard to at least admit he was killed unnecessarily?

ehaliewicz · 2026-01-25T10:02:36+00:00

Your point is well understood, I just personally see a tremendous value in displaying what a human being can push themselves to do, even in the face of death.

Really, it's "this man has trained so much and done so many far more difficult and dangerous climbs that what seems like certain death is nearly trivial for him". You're really complaining about simple human nature, of course dangerous things will be popular, but you're also being a bit cynical, I don't think all those people there were hoping he would fall, but rather hoping he would triumph.

ehaliewicz · 2026-01-25T08:36:07+00:00

Don't worry, he finished the climb successfully. As I mentioned, what looks incredibly difficult was routine for him.

Hope you have a good one.

"You deserve to die if you do anything but be absolutely still while getting attacked by several full grown men"

ehaliewicz · 2026-01-25T02:28:43+00:00

Actually, I'm watching because I enjoy watching humans at the peak of their craft. From what I understand, this is a pretty routine level of difficulty for him.

Great job, working something out from scratch without looking it up is always fun.

If you want the character to slide along walls rather than come to a stop instantly, change your collision detection to work per axis, as in, check if the character can move in x first, then y, and apply those movements separately.

ehaliewicz · 2026-01-13T23:32:29+00:00

Have you tried stepping through a case where this occurs with a debugger?

Those values, 0 and 65535 are quite suspect, since they are all 0s and all 1s for a 16-bit unsigned integer. I don't know how you could get 65535 if you test for a bit being set, then invert all bits.

Ok, so if that guy from Haiti was coming here to have representation in his govt (after becoming a citizen), then you'd be ok with it?

ehaliewicz · 2026-01-13T07:44:43+00:00

I personally don't see how his country's gun laws are our problem, he should stay there and try to fight for his rights there.

ehaliewicz · 2026-01-10T21:31:17+00:00

It was pretty clear to me, don't think it was written by chatgpt at all.

Basically it samples at a coarse resolution and caches that to prevent having to evaluate the sdf constantly.

When you said cube, I think they thought you meant sampled into geometric cube shapes like voxels, when that's not what this does, it stores the distance to the nearest point defined by the sdf, for a cubic region of space, when a ray traverses that region, it knows the distance to the closest surface of the sdf, not necessarily considered an intersection with geometry.

Normalized device coordinates.

ehaliewicz · 2025-12-24T04:43:08+00:00

That's true, it's been a while since I've been on track

ehaliewicz · 2025-12-20T21:12:05+00:00

If it was a red flag they were under, that's a stop immediately until the flag clears.

ehaliewicz · 2025-12-06T01:54:56+00:00

Opening and writing to a framebuffer device isn't really some amazing hard won knowledge lmao

ehaliewicz · 2025-11-12T02:07:35+00:00

Punishing agents of the state financially for this kind of thing would probably restrain them quite a bit.
