Support / EGL_BAD_ALLOC error
« on: January 21, 2015, 05:38:51 pm »
Hello everyone,

I hope I can get some help with an odd error.
I am getting this error a lot lately in the Google Developers Console:
Code: [Select]
java.lang.RuntimeException: eglSwapBuffers failed: EGL_BAD_ALLOC
at android.opengl.GLSurfaceView$EglHelper.throwEglException(GLSurfaceView.java:1077)
at android.opengl.GLSurfaceView$EglHelper.swap(GLSurfaceView.java:1035)
at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1333)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1116)
I got three reports of this error.
I found it odd that all three reports came from Android 2.2 devices.
Devices:
Galaxy Mini (GT-S5570)
IDEOS S7 Slim (qsd8k_slim)
Galaxy Precedent (SCH-M828C)

I hope that I can get some help with this error! :)

Cheers,
Abiram

Projects / Skin Viewer 3D
« on: January 19, 2015, 11:01:58 am »
Hey guys,

I made an app called: Skin Viewer 3D.
It uses jPCT-AE for the 3D viewer and the live wallpaper! :)

This is how it looks like:


I don't think most of you people here would be interested in a Minecraft app but make sure to check it out if you are! :)

Some code I wanted to share (how I added rain and snow to the app):
(I don't know if this is neat code or not, but I hope it might be useful to some people. I am a beginning Java programmer ;p)

SkinActivity.java (incomplete!)

Feel free to use this code.
This is not 3D snow though!

Support / Object3D's transparency issue
« on: December 06, 2014, 12:07:56 pm »
Hey everyone,

I had a hard time trying to register to this forums, so I used my schoolemail...  :o
Anyway, I have an issue with 2 Object3D's...
Both objects are cubed. They have individual textures on each face.
Both objects have this transparency value:
Code: [Select]
this.setTransparency(300);
Box1 is in box2. (their center point is equal)
Box1's dimensions: 2f * 2f * 2f
Box2's dimensions: 2.2f * 2.2f * 2.2f
Box2 has more transparent area's than box1.
However, box2's non-transparent textures don't seem to be visible...
When I remove
Code: [Select]
this.setTransparency(300); from box1, then those non-transparent textures do show up... (but then I get black-ish areas on the box1 texture...)

How can I solve this problem?

Cheers,
Abiram

PS: This library is AWESOME   ;D
