I have never been able to find an explanation of transformation matrices in 3D graphics that doesn't use specialised libraries and doesn't use coding practices of questionable efficiency.
So I tried making my own, but it makes no sense, yet it almost works.
Anyone on /g/ thinks it's redeemable?
Every frame:
>create camera matrix, starting with a translation matrix
>multiply by z rotation matrix, then x, then y
>translate by (0, 0, -1) (so that when the camera rotates, it doesn't rotate around a point in front of the camera)
>multiply by projection matrix, which is as shown
Every frame, per object:
>create object matrix, starting with a scale matrix
>multiply by x rotation matrix, then y, then z
>multiply by translation matrix
>multiply with camera matrix to get the transformation matrix
In vertex shader:
>create vec4 "position" by multiplying the transformation matrix with the vertex position (since it's a vec3, 1.0 is tacked on the end)
>define gl_Position in either of the following ways
>gl_Position = vec4(position.xy/position.w, position.z, 1.0) (causes layering issues and vertices behave weirdly as they go offscreen)
>gl_Position = position (cutoffs are no longer the near and far defined by the camera)
Sorry for recreating this thread, I got some responses that would have been useful with some elaboration last time, but my laptop briefly died and so did the thread.

Canonical 3D graphics code seems to use projective geometry, which is no longer taught as a working subject. I believe this is done so as to enable translations to be performed as matrix rotations, but it feels like a bit of a hack.
I'm sure someone in the 1970s thought this was a good idea, but the rest of us are stuck with no real theory as to why we must do things this way.

Read up on linear algebra, affine geometry and projective geometry, in this order.
You should be able to understand most stuff afterwards

It's misinterpreted by dumbasses.
Quantum computers don't make operations go faster, they're only faster for special types of calculations. Watching a movie or browing the internet on a quantum computer won't go faster than a regular computer, it might even go slower.

Is Rust a good language for a total programming newbie to learn? I've been self studying this and Python for a while, and I'm wondering if I should drop Rust for now. I like what I've read about Rust, (Safety & Control) and would like to continue with it.
My job requires the occasional repetitive task for testing purposes, and Rust seems like it would fit the job better for this over Python, because I don't need Rust to be installed.

Safety & Control for what? These words alone doesnt mean anything. On Rust context, they are most buzzwords than anything.
The real key there is just marketing: Rust have a built-in code analyzer which just say "Your code isn't good... Fix it". Nothing more, nothing less. Any good static analyzer would perform equally or even better.
What we really need is a methodology related to Project Guidelines: Better design outside the language scope.
>>
>>58912929
Ok. So does a lack of guidelines make the language bad for newbs?
>>
>>58912832
Rust is a fairly young and quite rapidly evolving language. It lacks the powerful, stable libraries available for C and C++, and the ones built in to Go and the higher level languages like Python, Java, and .NET.
Depending on what you're testing, having a binary program probably doesn't make much sense. It's unwieldy, while scripting is just the tool for the job. If installing python isn't feasible, look for the OS's built in scripting capabilities: powershell or bash.

Welcome to the /g/ meta thread. Here, we discuss ways we can make /g/ great again.
>this is against the rules
See https://desuarchive.org/qa/thread/675371/#677151
Hiro said we are allowed one meta thread per board.
How do you think we can MGGA? Proposals:
-Half the board is becoming generals, taking up space for potential threads. We can overcome this by placing a limit on the number of generals allowed at a time.
-Operating system war threads provide no actual content, and just end up being people throwing shit at each other. Ban them.
-There are currently four threads about TempleOS and Terry Davis. We need to limit it to one at a time, or /tosg/.
-Tech support threads still pop up every hour. Instead of helping people. we need to link them to /sqt/.
-The sticky doesn't contain enough information. If we also added infograpics like pic related, it could prevent unnecesarry posts.
What do you think?

I agree with banning the number of generals. Some of them are way too specific, and we could combine several into one.
