OK, TKS.

I mean like this:
public void onSurfaceChanged(GL10 gl, int width, int height) {
    gl.glViewport(0, 0, width, height);

    // make adjustments for screen ratio
    float ratio = (float) width / height;
    gl.glMatrixMode(GL10.GL_PROJECTION);        // set matrix to projection mode
    gl.glLoadIdentity();                                        // reset the matrix to its default state
    gl.glFrustumf(-ratio, ratio, -1, 1, 3, 7);           // apply the projection matrix   //The data will change for different device's camera.
}
So, I can't do it like this, if i use JPCT-AE?
Thank you!

Hi,
   Thank you for reply. I want to change camera PROJECTION View, but I can't find the interface from JPCT-AE.
I calibration camera for android and compute the camera matrix. Then I want to configure PROJECTION View. How can I do it in JPCT-AE?
Thank you again.

Hi, all
    When I use JPCT API, can i also use OpenGL ES API.For examples, I want to use follow code to update PROJECTION View.
gl.glMatrixMode(GL10.GL_PROJECTION);
FloatBuffer floatBuffer = FloatBuffer.wrap(new float[]{//data......});
gl.glLoadMatrixf(floatBuffer);
It will work?
Thanks!
