// create a transform with a translation of (1, 2, 3) btTransform transform; transform.setIdentity(); transform.setOrigin(btVector3(1, 2, 3)); // get the translation component of the transform btVector3 translation = transform.getOrigin(); // print the coordinates of the translation std::cout << "Translation: (" << translation.getX() << ", " << translation.getY() << ", " << translation.getZ() << ")" << std::endl;In this example, we create a btTransform object with a translation of (1, 2, 3). We then use the getOrigin method to retrieve the btVector3 representing the translation component of the matrix, and print its coordinates to the console. The package library for btTransform is the Bullet Physics Library (bullet3).
