Dear Mr.EgonOlsen,

I found out why.

Because I forgot changing texture name between "textureLocation" and "textureSelectedLocation".

Best regards!

Dear all,

I would like to change the texture of picked object.
I have tried:

.....
if (event.getAction() == MotionEvent.ACTION_UP) {

if (System.currentTimeMillis() - time < 1000) {
Object3D clickedObj = renderer.PickObj(xpos, ypos);

if (clickedObj != null) {
// set prevClickedObj for tracking
if(prevClickedObj == null || !clickedObj.equals(prevClickedObj)) {
prevClickedObj = clickedObj;
}

statusInfo.setText(clickedObj.getName());
clickedObj.setTexture("textureSelectedLocation");

} else {
// uncheck clicked object
if(prevClickedObj != null) {
prevClickedObj.setTexture("textureLocation");
}
}
}
....


With purpose highlight a picked object.
But it is not effect.

Please kindly advise!

Thank you so much!

Dear all,

I am developing a AR app.
Include:
Layers:
- Camera
- ARView with GLSurfaceView (using jPCT-AE): display object (latitude, longitude)
- Layout control: Compass, infomation status,...
- Logic: loading locations from server.

The screen can see camera. but ARView is blue in background like below:

I placed my phone on desk -> can see blue clearly.




Is blue default of screen color in JPCT-AE? How to change bg color of World?

Many thanks for yours help!
Sorry, if my E is not well.
