Yes but what is it how does it work

Blender gang

The only nodes u ever need

What else u need

@@timsonss math node

@@ClintochX More like Meth node amirite B)

I mean, it is essentially the same infinite texture, and people just sample it in different places and at different scales

@@amaryllis0 I would say the same, if you're familiar with noise types, this definitely makes sense, but I agree, it could be explained (shown) in a little more detail :)

Agreed, it's a massive oversimplification of what really amounts to RNG with varying smooth gradients between RNG values.

the title does make some sense but yeah it is slightly misleading. maybe "why all games texture the same way" would be more accurate

@@amaryllis0 could say the same about music, all the music is the same, part of an infinite music, just sampled in different places and scales

Yep like 2D random numbers.

Well it is a random number based system. Perlin is pretty much a grid with a random value at each vert and the interpolates between those points to get the final resolution. It's how its so relatively smooth.

@@USBEN. It can actually be N-dimensional, so you can have many more, i.e. 4D for volumetric fog over time

Technically it is, it just doesn't exist as an image, but rather an algorithm that can be used to create a texture, but it can definitely be displayed as an image

@@nofabe being an algorithm that can be displayed as a texture is different from it being directly a texture. Given any algorithm there's a conceivable way to generate a texture from it, but calling those algorithms textures in of themselves is misleading. Perlin Noise is just that, noise, it's a noise algorithm, you can represent that noise as colors on texture, but the noise itself isn't a texture. Perlin noise can be used to generate audio without having anything to do with pixels, does this make Perlin noise a sound? Perlin noise can represent a vector field, does this mean that it is a vector field? For example a sine wave isn't inherently a sound, but it can be used to create a sound, similar concept. I could go on. Just because an algorithm can be used as or presented as a texture doesn't mean it intrinsically is. A texture implies a certain connotation to it, of some form of color data, these are properties derived from, and not fundamental to, Perlin noise.

@@nofabe no it’s not

imma just blow up a nuke in blender to make some noise to wake up my neighbors

This!

If I recall correctly, I dont think the creator is an industry professional, so they probably are just explaining the things they know. Which is a bit unfortunate cause as a lot of people know, yeah simplex has been dominant for a while

honestly might warrant an entire reupload. It's kinda funny how almost every time he repeats it its wrong ;;

@@yveltalsea yeah clips don't really show when and how they are used, just random clips as well.

@@yveltalsea Meh it is fine, they are similar enough but a mention of simplex would have been helpful for new developers. Personally I would not even call code noise textures unless it is static :p But it makes for a nice video title. Lets not be too hard on someone making a nice video. Edit: thing is, people will probably discover Simplex on their journey to optimize it anyway.

Yes, Simplex noise - also designed by Ken Perlin, has a few advantages. It's faster/cheaper to compute and can easily do higher dimensions (4D, 5D, can be used to animate 3D noise over time like clouds).

also god i want this music to jam out to

Like, you don't actually say what it is, just that it is noise and it was made for Tron. But what is noise? What defines noise? What was the actual function Perlin came up with?

I'm even simpler. I see hehe funny priple lady can't cook jigel pufs sword and I click

Not Today Anne Paris hope that helps ❤

Perlin is the default and industry standard noise map. That’s really all he’s saying.

From what i remember dipping my toes into noise maps, it's abt as easy as getting a blank canvas and putting random splotches of grey/black all over it

Perlin noise is a stack of different noises. So you make one random noise texture that goes from 0 to 1024 that had blobs1024-ish pixels across. You then take a second random noise pattern that's 512 pixels across that goes from -256 to +256 and add that in. Then a pattern that's 256 across going from -128 to +128 and add that in. So at each level, you have blobs of half the size and half the strength added in.

You could always program it

Perlin Noise is a specific technique used to generate smooth random textures procedurally, so it’s usually a function in a program that figures out the color at a given pixel.
