resizing FrameBuffer and shadows

[raft]

I faced another weird situation. if I resize FrameBuffer when shadows are on, size change isn't reflected. FrameBuffer.getWidth/Height returns the correct values but buffer is rendered as initial size.

this is what I get by resizing 800x600 to 1024x768


reverse is also true. this is what I get by a resizing a higher resolution to 800x600


If I disable shadows and resize screen again, everything seems ok. but after enabling shadows and resizing I end up with initial size.

I've updated my driver twice and even made a bios  update.

and this is the sequence of rendering:

Code Select Expand

skyBox render / draw
clearZBuffer
world render/draw
shadowHelper.updateShadowMap
shadowHelper.drawScene
buffer update/display

really weird

and this happens all the time in the same way. not undeterministic

I see...i think i found the reason for this, i just can't figure out why the code does what it does...give me some minutes...

[EgonOlsen]

Please try this jar: http://jpct.de/download/beta/jpct.jar

[raft]

thanks, yes resizing is fixed now

however I have another weird problem. please see the video below. sometimes happens after resizing when shadows are enabled.

Looks like some threading issue...i anything (logic, rendering, input processing...) done in another thread. Is Config.useMultipleThreads enabled?

[raft]

Is Config.useMultipleThreads enabled?

not exclusively. it is left as default which is false I suppose (not in javadocs)

[EgonOlsen]

Yes, default is false.

Why are you actually doing this:

Code Select Expand


world render/draw
shadowHelper.updateShadowMap
shadowHelper.drawScene


? The shadowHelper.drawScene replaces the world render/draw calls. Try to remove that world render/draw part and see if that helps.

Why are you actually doing this:

because of being a shadows newbie I suppose. and not very clear in docs

Try to remove that world render/draw part and see if that helps.

yes, seems as it helped. problem was undeterministic but never happened in last trials. thanks

[EgonOlsen]

...and not very clear in docs

I agree. I'll make this more clear.

[raft]

Try to remove that world render/draw part and see if that helps.

yes, seems as it helped. problem was undeterministic but never happened in last trials. thanks

although very seldom, I still have this issue. possibly driver problem or?

[EgonOlsen]

I'm not sure...i looked like as if the scene was rendered using a wrong camera/camera matrix. Are you by any chance doing something in another thread that modifies jPCT related instances like moving the camera in an event listener or something like that?

[raft]

I guess no, I double checked it. GUI is based on TWL so all GUI events are handled in GL thread.

[EgonOlsen]

I've no idea what else might be the reason...
