This animation is a 3D ball playing animation. The animation uses the ball as a playing instrument. The ball slides up and down on the track and bounces on the springboard to successfully match the melody and rhythm of the music, thus playing the theme song "My Hrart Will Go On" of Titanic. At the same time, the animation reproduces three impressive classic scenes from the movie: kissing on the bow, dancing in the third class, and Jack falling into the sea while the most plank at sea is waiting for rescue. Through this 3D ball playing animation, I am committed to combining music and visual art. While showing my technical ability and creative ability, it is also a tribute to the classic film and music of Titanic. In order to realize this work, I used Maya software to wake up modeling, animation and rendering. I hope this work can bring a wonderful audio-visual experience to the audience, and trigger meetings and emotional resonance for the Titanic theme song and film.
