Kojack I'm still waiting on my Dragonbox Pyra.

So I stopped with the crowd-funding / pre-order nonsense. At some point, I went through my Kickstarter/Indiegogo history, and I had spent like $10,000 on a bunch of projects that simply disappeared and were never heard from again. Yeah, there were a few decent one that finished their project, but I would say the success rate is less than 50%. Not worth it. I will buy something when it is for sale and the team has proven they are serious.

I would still like a good portable computer, but the ones out now are either too big, too expensive, or not good enough. Had the GPD Win 2 for a bit, but it was heavy, and even with the full keyboard it was impossible to type. I thought it would be cool for development, but it just wasn't practical. And the ones that are the right size can't do 3D.

Anbernic I think makes solid hardware, but it's mostly for handheld emulation. This RG552 is absolutely perfect for PSP games. I did have a PSP, but I missed some good titles. Not everything works 100%, but for the most part you can run at 2x resolution and get 60fps. For the troublesome games you can run at the original resolution with frame skip, you'll still probably get 40 - 50 fps, but it works. Dreamcast is supposed to be perfect, and PSX is mostly working. Anything newer is a hit or miss, I see a few Wii / Gamecube games work, but otherwise not really. Anything older like 16-bit or MAME is great with quality upscaling to 1080p (or integer scaling) and 60 fps. So for emulation, it is the best I've seen.

This is what I use for a laptop now. The Lenovo Chromebook Duet (original model). I have a few better laptops, but this is small and light, and works fine for a browser. It was $200 when I bought it. This is about as small as you can get and still use a keyboard and see text on the screen. You can run Linux on ChromeOS, it's just a command-line, but they are beta testing GUI apps. But it's not stable, CLI works 100%. You can run like GCC and stuff like that, but it's not the best for development. But for traveling, it's enough for me, I'm not doing serious work on vacation.

I was trying to create a simple, 64 bit cat for a dungeon game. I don't care if you think the artwork absolutely sucks- if it does, I want to honestly know. Any thoughts?

some_lame_kid

Nerdzmasterz Bend the knee joints a little and it'd be a pretty cute cat.

I could tell it was supposed to be a cat. I'd say that makes it a success.

Nerdzmasterz

Sounds good, at least I successfully made a small cat that doesn't look like a dog or anything else.

I am a little off-by-one error :-)

Megalomaniak

Pixophir Solve the error and see 3 more pop up! Ah the life of a programmer am-I-right?

Audiobellum

So what do you think about what was said in this video?

Pixophir

Yeah, it is complicated. A lot of calculation depends on the placement and scaling of nodes of grid-meshes. And there is the space of raster positions in the quad tree, in the current height map texture, and that of world positions, which requires quite some to and fro on CPU and GPU.

Because I have chosen the way to not store too much data but calculate it on the fly, e.g. bounding boxes of those nodes and pass it over to the vertex shader, there is a lot of possibility to do this right, almost right, almost wrong, wrong, and not even wrong :-)

Will put the code that I have online soon(tm), but there is a lot more to do.

Energy efficiency across programming languages:
https://greenlab.di.uminho.pt/wp-content/uploads/2017/09/paperSLE.pdf

tl,dr: C, C++ and Rust top; Python, Perl and Ruby flop. Actually by two magnitudes of energy consumption. So if the first use 1 watt for a calculation, the last ones need 100 of those. That's bad, but not surprising ... 😎

The trouble with making use of that data is that they're doing very atypical work with their benchmark suite. Nearly all of the actual software I run spends most of its time reading and writing data. Nearly all of the energy most home or office computers use is spent idling. If you're not running your highly efficient C code 24/7, it just means you burn more electricity doing nothing.

It's interesting, but I'm running three computers at the moment -- two of which are at maximum load 24/7 -- and they use less energy altogether than two incandescent light bulbs would.

Edit: We could all save a lot of energy by playing nothing but 2D games. Who's with me? 🙂

Bone animation is expensive. Can it be optimized or use a different approach to character animation?

P.S. I'm writing here because I'm not sure that I need to create a new topic

Certainly not me. 😛

I've got the latest generation of Filament lamps, which I suspect are somewhat more economical than PCs. Can I use the saved energy to play 3D games? 😉

I'm curious, what could even be offered as an alternative to bone animation?

Tomcat

Kojack Yep, but it's a much heavier system than bone animation, and there's complaining that

Slava Bone animation is expensive.

so it's probably not the appropriate solution.

The old alternative used to be vertex morph animations, in games like Quake 1 and Quake 2 (the idtech engines didn't get bones until Quake 3). Every vertex had it's position captured for every frame of the animation. It made procedural animation and modding pretty damn hard. It also used a LOT of memory to store, but it allowed animation effects that are very difficult with bones (unless you have a LOT of bones).

Nerdzmasterz

I'd rather play 3D games in a VR world, with graphics that would make Fallout 4 envious.

Slava

Kojack Yes, I meant vertex morph as an alternative. Vertex morph consumes more memory, but saves computing performance?

some_lame_kid

Kojack That sounds like hell to work with.

cybereality

Bone animation is expensive in what respect? Memory, processing, energy usage? Even mobile phones today can handle a number of animated characters. What platform are you testing on?
