I am creating Augmented Reality in Android application, in which I have few POI and I am putting them on Camera Coordinates, Now only issue with this is nearby Coordinates are overlapping. I want to cluster the nearby Coordinates. Is there any way to do it. I am using this AR Project
Following is the code of OnDraw() method.
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (currentLocation == null) {
return;
}
final int radius = 30;
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setStyle(Paint.Style.FILL);
paint.setColor(Color.WHITE);
paint.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.NORMAL));
paint.setTextSize(60);
for (int i = 0; i < arPoints.size(); i ++) {
float currentLocationInECEF = LocationHelper.WSG84toECEF(currentLocation);
float pointInECEF = LocationHelper.WSG84toECEF(arPoints.get(i).getLocation());
float pointInENU = LocationHelper.ECEFtoENU(currentLocation, currentLocationInECEF, pointInECEF);
float cameraCoordinateVector = new float[4];
Matrix.multiplyMV(cameraCoordinateVector, 0, rotatedProjectionMatrix, 0, pointInENU, 0);
// cameraCoordinateVector[2] is z, that always less than 0 to display on right position
// if z > 0, the point will display on the opposite
if (cameraCoordinateVector[2] < 0) {
float x = (0.5f + cameraCoordinateVector[0]/cameraCoordinateVector[3]) * canvas.getWidth();
float y = (0.5f - cameraCoordinateVector[1]/cameraCoordinateVector[3]) * canvas.getHeight();
canvas.drawCircle(x, y, radius, paint);
canvas.drawText(arPoints.get(i).getName(), x - (30 * arPoints.get(i).getName().length() / 2), y - 80, paint);
}
}
}
