When I first time click on model to add red point (collision detection) the app freezes for 30 seconds ? Can you help what to do ?

On your CollisionController,
.
execute this,
.
"float[] point = CollisionDetection.getTriangleIntersection(collisionEventListener, objectHit, view.getWidth(), view.getHeight
(), view.getViewMatrix(), view.getProjectionMatrix(), x, y);"
.
on a separate thread like,
.
Runnable runnable = new Runnable()
{
public void run()
{
...
...
float[] point = CollisionDetection.getTriangleIntersection(collisionEventListener, objectHit, view.getWidth(), view.getHeight
(), view.getViewMatrix(), view.getProjectionMatrix(), x, y);
...
...
}
};

Thread thread = new Thread(runnable);
thread.start();
.
.
then wait for it to complete. (Show a progress bar if u prefer)

I am not aware of "Octree" so I want somebody to help me on same thing.

Hello @abhishekthanvi8
The Octree initialization is lazy.
It means it is build up the first time you use it.

The Octree takes some time to build. Time depends on the object complexity.

The use of a thread is an ok workaround. @dilipkold

from my understanding, the final solution would be:

• speed up Octree creation algorithm
• initialize Octree on background (configurable)

What engine is used to interpret the DAE model? Is this engine suitable for IOS and PC?
