I have a large scene with a lot of Mesh and MorphAnimMesh. I want to free memory when the meshes are removed. If i know right this is the best way to do:
for ( var i = scene.children.length - 1; i >= 0 ; i -- ) {
var obj = scene.children[i];
scene.remove(obj);
obj.deallocate();
obj.geometry.deallocate();
obj.material.deallocate();
obj.material.map.deallocate();
}
if i check the memory usage at task manager after this, nothing changes. ( tried to wait a few min for GC but nothing. ) Google Chrome memory snapshot shows the objects still there. morphTargets in THREE.Geometry @1862203 etc.
Tried to set the obj to null, but still no memory decrease.
Any idea what am i doing wrong?
Its a game with levels and the player can change from one to another. After a few change memory usage increases to really high. Thats why i want to remove all object from memory before the level change.

Reset to default 10Most likely, you need to add some, or all, of the following:
geometry.dispose();
material.dispose();
texture.dispose();
Check out these examples:

http://mrdoob.github./three.js/examples/webgl_test_memory2.html
three.js r.60
I did try all the dispose and deallocate methods but nothing worked.
Then I did the following for my ionic application which is using webgl renderer to render a 360 image.
this.renderer = new THREE.WebGLRenderer({ antialias: true });
RicohView.prototype.stopRendering = function () {
this.canRender = false;
this.renderer.forceContextLoss();
this.renderer.dispose();
console.log('renderer disposed');
cancelAnimationFrame(this.requestId);
}
requestId is something which can be captured from
this.requestId = requestAnimationFrame(render);
