memory leak #49
Comments
|
Google Chrome has had this issue for years now, the old OBJLoader had this issue in THREE.js and there's kind of a hacky fix to release the memory but it's not great. Fortunately for you, the Chromium bug just got assigned, coincidentally, https://bugs.chromium.org/p/v8/issues/detail?id=2869#c22 |

This heapened when I use Google Chrome .
When I load a big model (1GB) using the following code ,it uses a lot of memory
<!DOCTYPE html><html lang="zh"><head><meta charset="UTF-8"><title>Title</title></head><body></body><script type="module">import { OBJLoader2 } from "./jsm/loaders/OBJLoader2.js";( function () {let objLoader2 = new OBJLoader2();let callbackOnLoad = function ( object3d ) {console.log("success");};objLoader2.setModelName( "modelName" );objLoader2.load( 'test_model/test2.obj', callbackOnLoad, null, null, null );} )();</script></html>The garbage collection should clear the memory which stores the model , but it didn't do that,is
it memory leak?.
When I load using the following code,just add more line "
delete objLoader2.parser.contentRef;" incallbackOnLoadfunction<!DOCTYPE html><html lang="zh"><head><meta charset="UTF-8"><title>Title</title></head><body></body><script type="module">import { OBJLoader2 } from "./jsm/loaders/OBJLoader2.js";( function () {let objLoader2 = new OBJLoader2();let callbackOnLoad = function ( object3d ) {delete objLoader2.parser.contentRef;console.log("success");};objLoader2.setModelName( "modelName" );objLoader2.load( 'test_model/test2.obj', callbackOnLoad, null, null, null );} )();</script></html>the memory which stores the model will be clear;
