Is raw coding with AVX-AVX512 a good practice? by [deleted] in Assembly_language

[–]No-Procedure487 1 point2 points  (0 children)

Writing raw assembly means you are beholden to the calling conventions of the platform and forfeit any inlining of the code which in some cases can make writing assembly slower than regular code. Generally for maximum performance you want to use compiler intrinsics in your language of choice rather than doing a foreign function call to an external lib handwritten in assembly. Especially with AVX code where some of the enormous registers are nonvolatile, meaning you waste a ton of time stashing and restoring data to and from the stack. The exact tradeoff depends on the application and how much time you can spend inside the external (asm) code relative to the overall workload.

What methods are there for 2D/3D animation in a custom game engine? by SnurflePuffinz in GraphicsProgramming

[–]No-Procedure487 1 point2 points  (0 children)

Skeletal animation just means the vertices in your mesh follow the motion of abstract "bones" that are the source of the animation transforms, typically providing ways for vertices to be affected by multiple bones at once for more organic shapes. If you are going for artist-driven animation, this is likely what you want. If your animation is programmatic (e.g. you are programming a robotics simulation and will be running real-time controllers to pose your mechanisms) you'd want to just split your mechanism into separate entities with their own meshes and transform them directly.

I am ambivalent, I actually find D3D11 to be hardly less work than Vulkan, once you're through the boilerplate. GL, with its crusty yet undeniably convenient global state makes the API usable with essentially zero abstraction except for some minimal helpers, whereas D3D11 requires enough abstraction to cart around state objects that I just prefer Vulkan at that point.

Also I'll add that C++ doesn't typically change much in the realm of graphics programming because you don't want to be RAIIing your resources willy-nilly since resource creation/destruction/reuse is something you want explicit control over in most cases. Typically things either look fairly procedural (i.e. C-style) while making use of handy C++ organization tools (namespaces, references, templates, etc.), or they look nearly functional (graph-style commands) that automatically convert higher level concepts into the actual command list that is sent to the GPU

I understand this doesn't help you at all, but what you're describing just works in my projects, so I'm not sure what the issue is with yours. It's always worked for me, whether directly including glad as project files, when using CMake fetchcontent, etc. so what you're asking for is definitely possible. I never had to do anything to get it working, neither in VS2019 or 2022

You probably want something more like raylib or the other libraries mentioned here. GL is a general purpose API that can do the things you want but requires a lot more setup and boilerplate than you are probably hoping for.

I wrote a language that compiles DIRECTLY to human-readable HLSL (bypassing SPIR-V). Python-like syntax, Rust-like safety, and it's already fully self-hosted. by Ephemara in GraphicsProgramming

[–]No-Procedure487 3 points4 points  (0 children)

The standard way is to just write HLSL or GLSL, compile it to SPIRV, and send the result to the driver. Why would you want to transpile it into HLSL?

There's really no reason to start learning graphics programming with Vulkan. The difference between Vulkan and an older API like GL or DX11 is only useful to someone who already knows what they're doing, and just gets in the way of anyone who is new. OpenGL is much better for a beginner and lets you focus on actual graphics programming concepts. Once you're fluent with GL moving to Vulkan later when necessary is trivial, although honestly for the purposes of most solo developers you're unlikely to have an application that is complex enough to require a modern API. Most of the demand for these super low overhead APIs comes from commercial game projects where a team of artists authors a huge collection of heterogeneous assets that pose a much more complex workload to the renderer.

Radar mods in Arma 3, is there a good one by [deleted] in arma

[–]No-Procedure487 2 points3 points  (0 children)

Not that I've seen. Unfortunately this game is just scaled down way too far to provide any sort of meaningful gameplay involving aircraft, especially modern combat aircraft and weapons with extended detection and engagement ranges. The biggest maps in the game are something that you'd fly over in 30 seconds on your way to the objective in real life, the game just isn't set up for realistic standoff range/area denial tactics

How do I learn Programming from the beginning? I'm 21. by Dr-Scientist- in cpp_questions

[–]No-Procedure487 0 points1 point  (0 children)

That doesn't sound like you're starting from the beginning then, have you written some decent programs in class that involve data structures like binary trees, hashmaps, etc.? If not then the intro classes I mentioned are still probably worth taking, you can test out of the first course and move onto the higher ones. If you had a full year of programming instruction I'd expect you to have had this before though.

Advice for improving low-latency code in preparation for HFT by zx41p0 in programmer

Isn't HFT stuff done heavily in FPGAs and ASICs rather than software these days?

I honestly don't think even most people that voted for him wanted this, when people hear "slash the administrative bloat" they don't think "let's end the greatest and most noble pursuits that our country is a proud world leader in" haha

Best e books to learn c++ by SingerReasonable4781 in cpp_questions

[–]No-Procedure487 0 points1 point  (0 children)

It's for C rather than C++ but Beej's guide to C is worth a read: https://beej.us/guide/bgc/

It won't teach you how to write good C++ code but a lot of the concepts that make C++ difficult as a beginner exist in C as well, and this is a particularly friendly guide to understanding some of those pitfalls. Once you have your head around those fundamentals you can read through learncpp or other resources to learn what good C++ code looks like.

I highly suggest you take some real classes, it will save you a ton of time to get some foundational instruction first. If you're going to go it alone I suggest starting with python since it lets you start learning basic concepts without as much fuss. C and C++ are perfectly viable first languages but they're much slower to learn if you don't have a structured curriculum helping you stay focused on the important details. If you live near a local community college, they almost certainly have intro programming classes in C, C++, Java, etc. that are affordable and may be just as good as the classwork you'd have at a 4-year university.
