Hi Bernhard,

At moment 3D cache has almost any use in the current code.

If my branch get merged on day:
https://code.launchpad.net/~mrluzeiro/kicad/kicad_new3d-viewer
The 3D viewer will use that cached models to speed up the board loading (so there is no need to parse the model files and recalculate normals etc..)

The cache is global, on accord to last Cirilo email, that will be per user account.
There is a hash function that maps the real file to the cached data, also it checks for file modification (Cirilo can give more details about it).

Mario

+1 for the button or auto cleanup from my side.

What is cached there at all?
I just looked on my OS X setup and I found the cache folder, but it is empty.
And yes, I am working on a couple of boards with 3d models…

How is it in general thought to work?
Is it intended to cache whatever it caches on a per model, per project, per etc. basis?

Apart from that, (1) seems to be the right place for OS X.


Regards,
Bernhard

I am not sure having a manual button to click to clear the cache helps a lot... I think some autocleanup would be nice, but that does of course not exclude a button for those people who likes to click on stuff.

+1 on a "Clear cache" button/menu item
