Add icons for 3D texture classes

[MewPurPur]

Oh, and the old Texture3D icon is deleted. Its style clashed with the one I went for here, also it's an abstract class so an icon isn't that important. Texture2D hasn't got one for example

I can't visually recognize CompressedTexture3D and NoiseTexture3D.

[Zireael07]

Yep, Noise3d looks extremely close to generic Image3d...

[MewPurPur]

OK, let me revise

[MewPurPur]

I moved the cube configuration a little so ImageTexture3D has its white in different places. I'm ready to push the changes if they are liked.

I thought the NoiseTexture3D icon was showing something like fog. But it turned out to be 3D cubes when I open the SVG 🤣

I think using a flat image would be more easier to read. It does not have to be 3D since the image is like a sticker on a box.

[WhalesState]

have a look on this, it may be easier to recognize with a jaggy line

[MewPurPur]

Squares should be good and familiar from the 2D version. This idea could be used for an icon for the Noise class.

you can keep the cube and add a jaggy line over it instead of the smaller cubes

[MewPurPur]

I get you, but that's not what I'm saying. I'm saying I want to remain similar to this:

Anyway, next take, what do you think? It's not grid-aligned, that's impossible, but hopefully it's distinct enough to make up for it.

I personally like old ImageTexture3D more for sure, and honestly I also like the cubes more.

[WhalesState]

It looks good and clearer than the previous one, the icons size in godot are 16x16px, you can make it looks sharper if you snap the points to grid if possible, like this small edit.
the issue that makes them not recognizable is that you only have 9x7 pixels inside the cube front face to draw shapes and you should have one pixel margin to not make them connected means 7x5 pixels only.

[MewPurPur]

I'm not too strict about the grid, sometimes not making things grid-aligned allows you to make them larger, and therefore clearer. Do you have the SVG of your example? I'm pretty on board with the idea of keeping the 3D-ness, but only as an "easter egg" while the front faces are big enough to look comparable to NoiseTexture2D's squares. I'll test it later though

[WhalesState]

Do you have the SVG of your example?

the points are aligned now, it's fine to ignore the grid snapping to pixels but for such small size it will result in blur even if you slightly move a point, and this blur will make it harder to read when they render in the editor.

[MewPurPur]

Could we merge this as is, anyway? I'm pretty set on doing a follow-up PR exploring the Noise-related classes, so I could explore more alt designs there, it'd also allow me to maybe change up NoiseTexture2D.

#79722 @WhalesState I used the jaggy line here.

the jaggy lines looks cool.

The NoiseTexture3D icon is a bit difficult to make out if you don't know where does it come from.
I think #78903 (comment) might've been better.

[MewPurPur]

Alrighty, seems to be what everyone thinks, so I'll do another take on this one!

[MewPurPur]

Haven't changed anything important in this push, I'm still using the initial designs. Can't make anything I like more. And honestly I feel quite restricted on a PR that's about texture cubes, rather than Noise-related icons.

Meanwhile the PR that uses a jaggy line for FastNoiseLite also is getting a bit of a pushback, since the library doesn't have you think about noise functions and a jaggy line is not a familiar association.

So let's pls refine later, I could try to make a PR that re-imagines all three icons in a way that's consistent once this gets in.

[Calinou]

Tested locally, looks good to me. The icons are easily recognizable as 3D, which is usually the most important distinction (as you can't use those in places that expect 2D textures and vice versa).

Thanks!
