Lately I’ve been working with the THREE.js glTFLoader and I was curious about the memory footprint it has on the GPU. Precisely what I don’t clearly understand is how come a binary file that is 869B (simple cube) has a memory footprint of more than 200mb? I suppose this is not something related to …

Thanks for sharing the issue. As I said I don’t think this is THREE.js related, I see this in everything that loads glTF on web platform. It doesn’t matter if I use Chrome Task Manager or MacOS native Activity Monitor, footprint is the same. As for Memory Panel in Chrome DevTools I was not aware th…

[image] fanna: I see this in everything that loads glTF on web platform. Even if you don’t use glTF but any other 3D format you will see this footprint. It’s it important to highlight this, otherwise users might get confused.

The memory cost of geometry will be pretty much the same on the GPU as in the glTF file. PNG and JPG textures, which could be embedded in any model format, often increase in size ~8x once uploaded to the GPU, because they must be decompressed. The environment map used in most viewers is another pote…

Hi, I have the same problem. Have you solved this memory problem?

Memory consumption always depends on what is allocating memory in your application. If you can share an example with more details we may be able to help.

The most common source of this problem is textures. PNG and JPEG textures always consume more GPU memory than their actual file sizes. To check this for a glTF file: npm install --global @gltf-transform/cli gltf-transform inspect model.glb Example output, note the size vs. gpuSize columns: TEXT…

I don’t know how to release the GPU memory. I have several scenes, I need to check the scene and load different models. My solution is to remove and dispose the models in the last scene, then load the new models. The problem is after using dispose function, the CPU and GPU memory is not released. Th…

See How to dispose of objects | three.js for details on cleaning up the scene. If memory is not released then probably something has not been disposed as needed.

That doesn’t seem to work anymore - is there another way? [Capture]
