Blender is always ahead of the game because it uses Z-up but by default it gives you the axis rotation order that would be correct for Y-up.

This >>967255. The people who made the original 3D software used mathematical 3D convention, that is how we arrived at Z-up. Since this was already convention anything that came after and did it different is what got us into this mess. It's so ridiculous we haven't standardized it yet since having a unified standard, whatever we settle on, would simplify things so much.

Anon, in 3D graphics you have multiple transform spaces.

object space, view space, world space, uv space to name a few common ones.

to translate between these spaces your 3D sofwtare do matrix multiplication by various 4x4 matrices.
To have your UV coordinates show up correctly on your mesh you will do a multiplication by the relevant matrix in your software.

Then to have your UV mapped object appear oriented in worldspace amongst other objects you do another matrix multiplication such that it sits in world in the right orientation.
To then appear in screenspace (view) as if you where watching it from a certain vantage you multiply this worldspace by another matrix that is commonly called the 'World-View-Projection' 'WVP' matrix.'World Matrix' multiplied by your 'View Matrix' by your 'Projection Matrix'.

One can think of these transform matrices as mathematical operations that moves all vectors on an object from one set of dimensions into another set of dimensions
while preserving their relative relationship to one another. We commonly use a few very specific ones that are useful for the purposes of 3D graphics but it's really arbitrary vector math.
Like you can multiply the object space of an object by some matrix to have it appear in your screenspace as if not sitting in 3-space but in some wacky hyperbolic geometry etc.

There are a lot of things going on underneath the hood of your 3D program that you're obviously oblivious to and here you are pretending to know things while calling people names.

AI will replace any use for you as a modeling artist.

whether it be game related or animation. the industry is in decline of hiring on new users. it's really only good for self publishing at this point or just as a hobby. why would I spend thousands on 3D Studio Max or Maya or even bother with Blender when it lacks plugins for film special effects that 3DS has.

I gave up on 3D modeling a decade ago but need to stop using internet on my free time and felt like making a new years resolution to doing more creative shit and less chatty chat as I am doing now

y'all are niggers
there is a reason all cad/archvis-centric software is Z up, as building plans are top down, it was convenient to match the "ground plane" with X and Y on the 2d drawn building plan.
entertainment-centric software is the same, except the bulk of blueprints/concepts are usually front/side views, hence Y up
cue a bunch of different software growing up doing the same thing slightly differently and there you have this clusterfuck.

I have no idea why this isn't user-configurable in all of them, maybe aside of Minecraft. All it takes for conversion is one matrix multiplication, and to top it off the 3x3 matrix required is always exactly one unit value (either +1 or -1) and two zeroes on each column and each row. If you can't manage to code that in within 10 minutes, what the fuck are you doing in 3D programming?

If you use Euler angles at all in your code, you should re-educate yourself about things like "gimbal lock", "complex numbers" and "quaternions" before you are allowed to touch any 3D code again.

Also "projective plane" while you're at it.

For displaying the rotation as Euler angles, there's no reason to not make the display configurable in terms of order of rotations and orientation of the positive rotation is concerned.

Judging by the fact that absolutely no one in the thread brought troons up except for you, I'd say that not only are they living rent free in your head, they've settled down and had several generations that consider your head their "family home".

Well clip space is Y-up I guess, with Z as depth. But the convention for cameras is different than for the world. Blender uses Z-depth/Y-up for cameras, despite the world being Z-up.
