Support / Re: background video
« on: February 20, 2014, 01:03:04 pm »
Thanks guys for your replies.

I tried overrideTexelData with ByteBuffer first but could not get very far.

Then I tried SurfaceTexture and managed to get some progress. Now I have Audio playing but the video does not play.

so to test this, as a proof of concept, basically in the onSurfaceCreated of my GLSurfaceView.Renderer I create the media player and surface texture like this:

Code: [Select]
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
int[] texture = new int[1];

        GLES20.glGenTextures(1,texture, 0);
        GLES20.glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, texture[0]);
        GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
             GL10.GL_TEXTURE_MIN_FILTER,GL10.GL_LINEAR);       
        GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
             GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
    GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
             GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE);
    GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
             GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE);

int mTextureID = texture[0];

mSurface = new SurfaceTexture(mTextureID);
mSurface.setOnFrameAvailableListener(new videoTexture());

try {
AssetFileDescriptor afd = getAssets().openFd("test7.mp4");
MediaPlayer player = new MediaPlayer();
    player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
    player.setSurface(new Surface(mSurface));
    player.prepare();
    player.start();
    player.setLooping(true);

} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}

and then I have this class:
Code: [Select]
class videoTexture implements SurfaceTexture.OnFrameAvailableListener {
@Override
public void onFrameAvailable(SurfaceTexture surfaceTexture) {
updateSurface = true;
mGLView.requestRender();
}
}

and finally in my onDrawFrame method I have:
Code: [Select]
if (updateSurface) {
                mSurface.updateTexImage();
                updateSurface = false;
            }

I really appreciate your input  :)

Support / background video
« on: January 20, 2014, 07:49:33 am »
Hi,

I am trying to add a video to my game background. I tried FrameBuffer.blit method and changed the background texture on every frame but this is very slow and maxes out my memory pretty soon.

Is there any other way to display a video on the background?

Cheers

Thanks Irony, I am at very early stages at the moment but what I have in mind is very similar to your game. I'll let you know if I have any questions. Thanks

Thanks I really appreciate being showcased on the project page :)

I have already started working on a space dogfight game. Hopefully this will have a wider audience.

Projects / Mohr's Circle app - a learning aid for engineering students
« on: October 25, 2013, 12:46:49 am »
Hi All,

I finally published my first app. It is a learning aid for engineering students to understand advanced 3D stress analysis. I used JPCT for my sensor orientation. also almost all of the rotation calculations are handled by JPCT.

This App only works on devices with Android 4.0 or higher. Also it works best on HD devices (e.g. HTC One).

Support / Re: setRotationPivot translates my object
« on: September 19, 2013, 01:12:46 pm »
Thanks for the quick response. but I really get my objects translated with the setRotationPivot method.

This code

Code: [Select]
xConeLeft = Primitives.getCone(90, 2);
xConeRight = Primitives.getCone(90, 2);
xConeRight.setAdditionalColor(new RGBColor(0, 0, 255));
xConeLeft.setAdditionalColor(new RGBColor(255, 0, 0));
xConeRight.rotateZ((float) -Math.PI/2);
xConeLeft.rotateZ((float) Math.PI/2);
xConeRight.strip();
xConeLeft.strip();
xConeRight.build();
xConeLeft.build();
world.addObject(xConeRight);
world.addObject(xConeLeft);

xConeRight.setRotationPivot(new SimpleVector(10, 10, 10));

results in this image:



and this code
Code: [Select]
xConeLeft = Primitives.getCone(90, 2);
xConeRight = Primitives.getCone(90, 2);
xConeRight.setAdditionalColor(new RGBColor(0, 0, 255));
xConeLeft.setAdditionalColor(new RGBColor(255, 0, 0));
xConeRight.rotateZ((float) -Math.PI/2);
xConeLeft.rotateZ((float) Math.PI/2);
xConeRight.strip();
xConeLeft.strip();
xConeRight.build();
xConeLeft.build();
world.addObject(xConeRight);
world.addObject(xConeLeft);
results in this image


however If I don't have xConeRight.rotateZ((float) -Math.PI/2);
then it all works fine.

Support / setRotationPivot translates my object
« on: September 18, 2013, 02:40:44 pm »
Hi,

I am having a very hard time understanding how setRotationPivot works on AE version

When I do the following

Code: [Select]
xConeRight.setRotationPivot(new SimpleVector(15, 15, ,15));
it is the same as if I was doing

Code: [Select]
xConeRight.translate(30, 0, 0);
and then when I call rotateX or rotateY the object actually rotates around point (15, 0 ,0 )

I appreciate any help.
