[fixed] Increasing memory allocation (interpolation cache)

[uuu]

G3D Viewer v1.3.6
Windows Vista Service Pack 2 32bit

I forgot to close G3D viewer (with animating model loaded - "megapack/tech/battlemachine attacking" if it helps), when I came back (cca 1/2 hour), it used 1700MB of memory (it would use more, but pagefile+hdd activity slowed it's hunger), even though initially it uses only about 57MB of memory. You can actually watch the memory consumption to grow.

I can reproduce this on r3497 with

Code: [Select]

./start_megaglest_g3dviewer ../../data/glest_game/techs/megapack/factions/tech/units/battle_machine/models/battle_machine_attacking.g3dAfter 5 minutes of runtime, the memory consumption has tripled. Without a model loaded, there is no change in memory consumption.

When I "clear all", memory allocation stops increasing (but also doesn't decrease). When I then load the same model again, memory allocation still remains on the same elevated amount (but it may continue increasing the previously used memory is filled up again).

Another issue I have here is that the menu does not display, or rather it is 1 pixel high, so I can only access it by pressing F10.

Give svn a try and let me know if the leak is resolved.

Thanks

r3498 does not fix it for me, yet. Memory allocation still doubles after 3 minutes.

Found a cache that was taking way too much RAM (interploation). I hace turned it off and we should now see in both the viewer AND the game a lot less RAM usage. Hopefully performance is still ok.

Memory consumption of the G3DViewer looks good to me now. I'll take a look at memory on the next game we play on head of trunk.
Thanks!

I've played a game with Pizza with a build which has the interploation cache disabled and there was no noticeable performace difference. We did, however, forget to take a look at how memory allocation has changed, but I guess it's safe to assume it will be lower now. I'll tag it as [fixed], but  more testing will be good.
