Abstract

This is an interactive animation created using C language, with support from the OpenGL, GLUT and the SDL frameworks. The concept behind this animation is to utilize the functions provided by OpenGL to achieve visual effects involving lighting, texture, motion, modeling and interaction.

Based on experiment and research on various libraries, the Simple DirectMedia Layer (SDL) framework was chosen to implement an audio frame buffer to play background music. The animation involved significant mathematical calculation in terms of motion and modeling. The animation is an underwater scene that contains randomly generated bubbles, a dolphin and a whale. Textures were applied to surrounding surfaces that construct the underwater environment. Lighting was optimized to make all the objects in the scene visible and genuine. Timing was adjusted to obtain smooth rendering. The dolphin and the whale were constructed vertex-wise using display lists.

In terms of interaction, the animation allows users to traverse the scene using keyboard input. Users can also choose to play and stop background music, which was composed using GarageBand.

The animation has met the proposed requirements. The OpenGL application programming interface (API) provides a basic and easy-to-use library for 2D and 3D graphic development. It constitutes the foundation of higher-level platforms such as Blender and Autodesk Maya.

This report is presented as a “system requirements specification,” augmented with explanations of various technical issues and certain implementation consideration.
