Attached is my shell script to produce a screencast,
i.e. capture the desktop (or part of it) and produce an mp4.

Thanks for the script Sven.

I have just added some NEWT support into JMonkeyEngine 3.0. How are handled touch input in NEWT? Do they simply generate mouse events?

Does headless rendering work with NEWT?

We don't differentiate touch or pointer.

We support multiple concurrent pointer events (multi-touch),
which is currently only impl. for Android.

The demo TextureSequenceCubeES2 (line 107) shows how it can be used
for a 2-finger zoom:

You mean w/o AWT, i.e. that -Djava.awt.headless=true ? Ofc.

Yes I meant with java.awt.headless set to true.

How can I make a distinction between an event coming from a touch screen and an event coming from a real mouse? Does an event coming from the mouse always have a pressure set to zero?

That is a good question, right now I don't know.

On Android we only have either or machines set-up right now
and sadly I have non X11 machine avail w/ touch.

At least I could add a 2nd mouse/pointer I guess to test multi pointers on X11 .. etc.

Maybe it is a good idea to have something like 'enum PointerType getType(intindex)',
if the NEWT driver can differentiate it. Don't know how at this point thought.

IMHO best would be to have a real world use case w/ machine and see how that goes.

Correction, MouseEvent has:

/**
* @return the pointer id for the data at index.
* return -1 if index not available.
*/
public int getPointerId(int index) { ...

If MouseEvent is constructed via the single pointer constructor,
i.e. no array of pointer [currently: X11, Windows, ..]
then the pointerID of index 0 is -1 - even though index 0 does
represent the single pointer count.

If MouseEvent is constructed via the multiple pointer constructor,
i.e. w/ array of pointers [currently: Android]
then the pointerID of each index [0..count-1] will be >= 0.

Integer pointerID's semantic is machine/OS dependent.

How can I check this semantic under Linux but with a touch screen without testing it with a real tablet? Which native API call is done under the hood?

You would need to change the NEWT X11 implementation to receive more
than one mouse event .. or something - similar like on Android.

I haven't looked into X11 event handling regarding multiple pointer events,
i.e. multi-touch - where 2 events are not sequential but one w/ multiple
'pointers' involved -> 2 finger press/swipe/etc.

If we could 'detect' these semantics, then you could create an appropriate
MouseEvent (the multi pointer ctor one) .. and dispatch it.

Ardor3D is going to use my renderer based on JOGL 2.0 very soon, Renanse asked me to make the pull request:
https://github.com/Renanse/Ardor3D/pull/4

Merge done by Renanse.

Re: JOGL 2 support for Ardor3D, JMonkeyEngine 3, jzy3d and NiftyGUI

I'm curious, are the Ardor guys going the multiple-backend route, or are they eventually going to make
a decision and go with a single backend....have they given any indication what their plans are?

Hi Harvey

Ardor3D allows to use AWT and NEWT, I added some high level canvases based on NewtCanvasAWT and GLWindow.

Ardor3D (<=1.0) allows to use shaders even though its architecture is not entirely shader-based unlike JMonkeyEngine 3.0. According to Renanse, Ardor3D 2.0 will only have a shader-based architecture, it won't work at all without shader support but I disagree with this choice. It is probable that we will have several working renderers like in JMonkeyEngine 3.0. This one officially requires shader support but there is still a renderer based on the fixed pipeline.

This post was updated on .

Hi

The user's guide of JogAmp's Ardor3D Continuation is now available here, enjoy

I remind you that JogAmp's Ardor3D Continuation is the subset of Ardor3D that I go on developing and maintaining.

Great news! I was upset when I found that ardor3d was dead earlier this year.

Personally I don't have the time (nor inclination to do it) but if some JOGL-knowledgable person feels like it the jMonekyEngine team sure could use some help in maintaining the JOGL-renderer in the upcoming 3.1 release

Given that I don't know a lot about JOGL APIs and I haven't actively used jME in several years I will be glad to help with what limited time I have. I do like both the JOGL and jME projects. gouessej - please don't hesitate to ask for help and I'll do what (little) I can.
