Dear all,

I would like to change the texture of picked object.

Code: [Select]
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;


} else {
// uncheck clicked object
if(prevClickedObj != null) {

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

Please kindly advise!

Thank you so much!

Dear all,

First, I have tried some time to get default XYZ coordinate and direction (NEWS).
The result runs well.

But today, the result is not correct as I think.

Everybody please kindly confirm below coordinate is correct or not?
And help me change if it is not correct.

Dear all,

I am developing a AR app.
- 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!
