Support / Initialize OpenGL ES for PowerVR, need to test on device
« on: July 02, 2011, 04:37:57 pm »
Hi,
I need to test my app on phones w/ PowerVR GPUs. It works fine on my HTC Desire and other phones with Adreno GPUs but I'm getting error reports from people with PowerVR GPUs. Without LogCat logs I'm clueless about origin of errors.
My app doesn't use JPCT-AE, it uses very simple OpenGL ES 2.0 object rendering.

You can download apk file here: http://dl.dropbox.com/u/7197208/LiveWallpaperRoseFree.apk
It's a live wallpaper, not a regular application. Please set it as wallpaper and if it crashes please send me LogCat logs either by sending them to keaukraine@mail.ru or attaching them to replies in thread.
I've added additional logging to determine if GL config is chosen correctly.

Thanks in advance!

I've made this in collaboration with my brother in approximately 2 days:

I just like my HTC Desire :)

Support / Transparent polygons sorting
« on: May 02, 2011, 09:50:05 am »
Hi,
I have an object which has only transparent triangles in it. The problem is that triangles are messed up in JPCT-AE. Does it have option for better triangle sorting algorithm? If not, please take a look at it, because I've had this problem with my previous app and had to calculate z-order manually which I can't do in current situation.

You can watch a video here: http://www.youtube.com/watch?v=lJtHyJDjtjM&feature=related (sorry, it is badly focused).

It is already present on the Market.

Support / Getting error Tried to set an undefined texture as default!
« on: December 22, 2010, 03:42:33 pm »
I've got a few error reports with the following exception:

Code: [Select]
java.lang.RuntimeException: [ 1292804064901 ] - ERROR: Tried to set an undefined texture as default!
at com.threed.jpct.Logger.log(Logger.java:159)
at com.threed.jpct.Object3D.setTexture(Object3D.java:3230)

Does anybody have some clues of exception's origin?

It seems that the problem is somehow connected to Motorola phones, so I need somebody with Droid to test my app.
If somebody wants to help me in testing app, please contact me.

Support / Framebuffer problem?
« on: December 19, 2010, 04:49:15 pm »
I'm making live wallpaper.

If you set wallpaper and then go to live wallpapers and launch it for preview, after returning back to home screen textures for transparent objects get changed in random order.
If I change device orientation, it will re-create framebuffer and everything is OK.
I can't track the moment when I have to re-create framebuffer because these are two different processes for 2 wallpapers.
Apparently something bad happens to framebuffer, please give me some recommendations.

I've made live wallpaper using jPCT-AE.
It comes in two forms: free and paid.

More details on both versions find here:

Support / Moving texture
« on: December 02, 2010, 02:03:09 pm »
Hi,

How can I change texture UV coordinates to move it in some loop?
I want to achieve effects like falling rain drops (place some transparent polygons with rain texture and continuously move texture in the bottom direction to achieve desired effect), or grass waving on the wind (move texture in the left/right direction), water running in the river, etc...

Support / renderScene() not applying changes to objects
« on: November 25, 2010, 08:32:53 pm »
After opening another instance of activity previously launched activity makes some re-initialization stuff after which renderScene() call seems to be ignoring rotation made to objects.
Camera rotates as usual, but transformations are not applied to objects, they keep their old transformations applied.

In short, it behaves like renderScene() doesn't do any work.
Calling world.buildAllObjects() before renderScene() doesn't work as well.
Please explain what needed stuff can be lost after re-initialization or may be if it's a bug in JPCT-AE, fix it.

Support / Specular lighting
« on: November 23, 2010, 07:55:13 am »
Hi,

I am trying to add specular highlights to objects.
I've set world ambient light to (90,90,90) and placed light with intensity of (250,250,250) 100 units afar from object.
As I rotate camera around object, I don't see specular highlights. I haven't tried moving light itself yet, will specular be more noticeable in that case?

May be I haven't set something up correctly? Objects are loaded from serialized data. Config has default values for specTerm & specPow.

Support / Loading serialized objects problem
« on: November 20, 2010, 06:59:07 pm »
Hi,

I have a scene which consists of few objects.
If I import them one by one into 3D Studio, their positions fit each other perfectly.
But when I try to load set of serialized objects in jPCT-AE, they appear in wrong positions.
I suppose it is because of re-calculating object's origin which happens after build() call.

Is there a way to get object being loaded exactly into the same origins as they were placed in 3DS files?

Support / Pre-computed light maps
« on: November 15, 2010, 08:19:41 am »
Can I use pre-computed light maps with jPCT-AE? Does it support multi-texturing so I can apply pre-computed shadows on objects?
If it doesn't support this, vertex coloring also can be handy in this situation. Does engine support coloring of certain vertices? This way I also can make some parts of objects darker and lighter.

If jPCT-AE doesn't have this feature (vertex colors) please add it, I suppose it isn't very hard to implement.
