ImageBitmapLoader: Cache promises to deduplicate requests. #27270
Conversation
sampleRenderTarget is being deleted and set to null by super.dispose(); the check for undefined was incorrect causing an attempt to call dispose on a null object.
Fix code style.

Something is wrong with the PR since the diff is the same as #27106. |
So that if multiple calls to load the same image come in, before the first one is loaded it will still only load it once.

🌳 Bundle size after tree-shakingMinimal build including a renderer, camera, empty scene, and dependencies.

Thanks, something got out of sync. Fixed now. |

I'm also looking into this for my project! Just a question, is there a benefit to doing it this way—introducing promises to three.js/src/loaders/FileLoader.js Line 4 in 9c5fcd3 three.js/src/loaders/FileLoader.js Line 53 in 9c5fcd3 |

@sxxov That is a good question. The solution of this PR tries to achieve the same (monitoring pending requests) like what is already implemented in I tend to prefer the promise based solution though. The approach in |

Description
Currently I am loading several GLTF files that reference the same texture. Since those calls all come in before the textures have downloaded the cache is failing.
This PR adds the promise to the cache so subsequent calls can see that the fetch is in progress and it will wait for them rather than downloading again.
