Bypassing GPU for mesh loading and reading

[slapin]

Hi, all!
For several purposes (physics, procedural generation) I need to load some Ogre's .mesh and .gltf files directly bypassing uploading them to GPU
as it is useless clutter there and might become a problem later, as this is information being interesting on CPU side, but also I'd like to benefit from format support and not reinvent wheel writing my own custom mesh format/loader. Any ideas? As special note because of need of some auto batch processing that would be important to be able to run in total GPU-less headless environment totally in software.

would this work for you?

Will try that, thanks!

Well, I found no way to use it when loading mesh from file.
I'd appreciate an example.

Code: Select all

DefaultHardwareBufferManager dmgr;
auto mesh = MeshManager::getSingleton().getByName("my.mesh");
mesh->setHardwareBufferManager(&dmgr)
mesh->load();

Thanks a lot!

Code: Select all

DefaultHardwareBufferManager dmgr;

crashes in case there is hardware buffer manager already initialized (in normal app).
It works in headless tool but I need it to work in normal app too.
If I don't use it I get everything through GPU

use DefaultHardwareBufferManagerBase
