frustum culling

[EgonOlsen]

I've uploaded a new jar here: http://www.jpct.net/jpct-ae/download/alpha/jpct_ae.jar

That should fix the near-plane-blitting-issue in most situations. The problem is/was, that the blitting happens in fixed point coordinates while the near plane is defined in float.
In addition, this jar includes a change for animated objects. In former versions, animated objects reverted to simple vertex arrays even when VBOs were enabled, because i had a problem with updating the meshes otherwise. This should be fixed now. VBOs are also default now, because on current hardware, it makes no sense not to. Isn't the play field in Jumpy actually one large "animated" object? Maybe this version can improve performance somewhat with this!? .(or maybe it doesn't even work...please give it a try and let me know...

right, indeed a few large objects. static tiles, dynamic tiles, dynamic items..

this jar works ok, but performs worse on N1. on my test level it was:
* doing nothing: 31 fps
* moving around and collecting items: down to 20 fps

with new jar:
* doing nothing: 26 fps
* moving around and collecting items: down to 13 fps

maybe it's just N1?

[EgonOlsen]

Try to default back to vertex arrays by setting Config.useVBO=false; and see if that is faster again.

[raft]

yes, it's definetely faster this way. so we conclude to what, every device has a different nature

oh, and can you please provide me a test jar that that is mentioned in this post:

[EgonOlsen]

Well, i guess i'll set the default back to false then. Not enabling VBOs on a device that could do faster with them enabled doesn't hurt as much as this, so it's the better default. On my phone, the setting just doesn't matter...it's all the same performance wise.

I've updated the jar with the timing output. Enable it with Config.timingOutput=true;. Let me know if you need more data for other operations.

[raft]

thanks, provides very valuable information for me

[EgonOlsen]

Sooo...is it a bottleneck or not?

Another question about the performance characteristics of your game: You are touching the object3d only if something changes, don't you? So no change in geometry...no vertex upload...correct?

[raft]

possibly it's the lagging factor but not too bad. at least on N1. there are few logs that take two digit milliseconds.

correct, i touch objects when i change them. 2 things trigger an upload:
* hide a subobject (less frequent)
* move a subobject (need to be done every frame) possibly this is the causing the noticable lag

[EgonOlsen]

I don't have access to the emulator ATM, so...when compiling the object for the level geometry, does it say that it uses mapped access or direct?

[raft]

i'm not sure what you mean. here is the complete log while loading level zero

I meant this one:

Code Select Expand


Vertex indices will be mapped!


Thanks for the info. I was just thinking about some optimization idea, but i guess it wouldn't work anyway.

You might want to give the jar in this directory a try: http://www.jpct.net/jpct-ae/download/tmp/test/

It adds support for an accelerated buffer copying via libgdx's native libs. The parts of libgdx needed for this can be found in the zip in case you don't want to download the complete libgdx.

Let me know if it works and does something good for performance.

it works but i didnt notice any particular speed up during game play. upload timing logs seems to stay low but only a few entry is logged so i cant say for sure what's going on later.

btw, i didnt notice any log saying something like "native upload enabled". i first tried new jar without libgdx jars and waited for a crash but that didnt happen. then added jars, set Config.disableNativeBufferCopies to false but i'm not sure if it's actually used. only difference i noticed is, old way continuosly logs uploading times, native one logs a few times.

[EgonOlsen]

The jar works with and without libgdx. There should appear a line in the logs that indicates if it's used or not. It starts with LIBGDX...
The lack of log messages might be caused by the fact that the libgdx path uses another render backend and i might have forgotten to add the timing log to it.

i'll profile the application. uploading doesn't seem to be bottleneck here
