COM3503 3D Computer Graphics Assignment

My assignment for the 3D Computer Graphics Module at the University of Sheffield. Achieved Grade: 71% (First Class).

Start

The main start of the program is Museum.java in the start package. When starting the program, make sure JOGL is added to the path.

From Terminal

• Compile all the classes with javac;
• Start the program with java Museum. The Museum.java file resides in the start package;
• You might need to alter the paths in TextureLibrary and Shader for the program to find the images (src/textures/images) and the shaders (src/core/shaders) respectfully.

Script File

• Start the start.bat file to start the program;
• You might need to alter the paths in TextureLibrary and Shader for the program to find the images (src/textures/images) and the shaders (src/core/shaders) respectfully.

IDE

• The program is developed with IntelliJ IDEA;
• Start the file Museum.java;
• You might need to alter the paths in TextureLibrary and Shader for the program to find the images (src/textures/images) and the shaders (src/core/shaders) respectfully if you are using a different IDE.

About

The Assignment was to model a museum room, which consists of different objects with different specificities. The room has a robot which is exploring and can be displayed in 5 poses. Some of the core features are outlined below:

• The mobile phone and the egg exhibits have specular and diffuse light mapping applied;
• The spotlight is swinging and its effects can be seen on the ground;
• The view through the window has texture effects applied, hence it appears that the clouds are moving;
• The robot is a hierarchical model and is capable of making 5 distinct poses by varying its rotation, eye, lip, ear, head and body movement;
• The robot gains awareness that the world around it is an empty dark abyss, hence during animation it looks at it with caution.

Maintenance & Extendability

The Assignment was developed in such a way, that it could be extended as a future project if needs be. Hence, the classes are structured into packages and are aimed to be extended easily. A few examples of this could be:

• Robot could have more parts added to it, by defining the part in RobotPartName.java and RobotPart.java and extending the relevant constructors in RobotPart.java and Robot.java;
• More objects could be added to the scene by extending ConstructedObjectBase.java and only implementing the getCalculatedMatrices() method, which defines object shape and position;
• The vertex and fragment shaders could be reused, as their names indicate their primary purpose and are reused throughout the project to save resources;
• User Interface is contained in InterfacePanel.java class and it could be easily extended to support more button;
• Etc.

Development

• OpenGL and Java is used for the development of this project. Due to java being used, JOGL is equipped to work with OpenGL libraries;
• GLSL files are used as vertex and fragment shaders.
