![After learning about FinalizationRegistry, I also learned about the using statement:
The using declaration declares block-scoped local variables that are synchronously disposed. Like const, variables declared with using must be initialized and cannot be reassigned. The variable's value must be either null, undefined, or an object with a [Symbol.dispose]() method. When the variable goes out of scope, the [Symbol.dispose]() method of the object is called, to ensure that resources are freed.
It's useful in scenarios where you might otherwise use a try/finally, e.g.:
let normalMap;
try {
tex = textureLoader.load('muppet.jpg');
tex.doSomething();
// …
} finally {
tex.dispose();
}
With a using statement, and assuming the texture object implemented [Symbol.dispose](), you could write it like this instead:
using tex = textureLoader.load('muppet.jpg');
tex.doSomething();
[Symbol.dispose]() will be called when tex goes out of scope. Unlike FinalizationRegistry — but just like a finally block — it's guaranteed to be called, so you can depend on it (in environments that support it).
It's currently supported in Chromium-based browsers, Node, and Firefox, but not yet in Safari. It's also been supported in TypeScript since v5.2, which was released in August 2023.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:zcycfvljdjkc2ywtj33blgdl/bafkreidukmuj4ospd7bsbl7rbpe6e5rydnbw2qqgkofxtwznwr5q35aaya@jpeg)
![Required dispose
A non-obvious thing is how to deal with objects that must be disposed. In other words, if a programmer accidentally writes const instead of using, can we catch it? For many scenarios, we can — by writing a getter for [Symbol.dispose]():
import assert from 'node:assert/strict';
class MyResource {
constructor() {
this._using = false;
}
doSomething() {
assert(this._using, 'Did you forget `using`?');
// …
}
get [Symbol.dispose]() {
this._using = true;
return () => {
// Actual dispose logic goes here.
}
}
}
using res1 = new MyResource(); // ok
const res2 = new MyResource();
res2.doSomething(); // Throws](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:zcycfvljdjkc2ywtj33blgdl/bafkreicqcjuhplvwl5lhbsz2bm2oukphpanscstaquhqdmjvmvt2kqvyki@jpeg)

The base #material of the water is a #blendedmaterial with two different #maps used. One is for the #mask and another is for the foam. There is a #normalmap used in the #bumpchannel. Keep a close watch to creativesnext.com for #3dassets.

I discovered a silly hack to use image2image like it's Control-net. You take a depthmap, or a normalmap and just load it as the image on the image2image tab, adjust the denoise to 70-75%... do your prompts and other settings, generate.

この提案手法のベストモデルと呼ばれている2 bounce までのではLambertだとまだ黒つぶれが消えないので、私の実装したのと同じ提案されている別の手法で最大反射回数を100とかにするとこんな具合にNormalMapの影響がかなり薄くなります。これはだいぶ私の実装のやつと似た結果だと思います。

And the logical next step, of course, is the implementation of the ‘object3d_normal’, which renders the object's normalmap!

Every asset was shot with the Normalmap-inator set to MAX.
And I wouldn't have it any other way.

Are you using a tiling noise texture for the latex/plastic normalmap/grains? or is it actual baked texture.
looks good.

Normal mapping purple majesty potatoes is surprisingly therapeutic. Trying out a few different methods of normal mapping here so that we can have some fun effects like swinging fluorescent lamps in the interrogation booth.

このスレッドが参考になりそうなので後で読む。結構最近のBlenderのCyclesでのNormalMapの問題に対処しようとするスレッドのようで、NormalMapのせいで裏からヒットしたりレイがめり込んだりという問題について書かれているよう。

だめだ。デカールシェーダーにnormalmap適用しようとするとそれだけでだいぶ難易度があがってしまう。
とりあえず現状のunlit版で出して、「これ以上はプロ用のツール使ってくれ」が正解な気がする。

Does this means that every textures of the games are like tripled for the specular/metallic/roughness and normalmap ?

I don't really know how to edit NormalMap while keeping transparency. I duplicate a large number of layers to create a pseudo-opaque image and set the transparency to 50% at the end. Crude method, but at least easy. #Koikatsu

...and custom water normals! This here is a mix of a "ripple" normalmap and a regular water normalmap, applied to a refracting material. Underneath it is water (but you can't see it) which allows for the water properties (splashing) to remain.
