Computer Graphics assignments

Computer Graphics project, built entirely with OpenGL and C++.

Structure

The project is structured in consecutive assignments, one of each is based in the previous work. This repo contains:

• Assignment 1 - PLY model visualization: Model visualization of PLY files.
• Assignment 2 - Poligonal models: Model generation, surfaces of revolution.
• Assignment 3 - Hierarchical models: Hierarchical model generation with several degrees of freedom.
• Assignment 4 - Illumination: Illumination control in a more complex scene.

Installation

The libraries freeglut and libjpeg (in its development version) are needed in the compilation process. These libraries are available in the majority of Linux distributions. For compiling and/or running with the default settings, execute the following order:

make

Once the project is compiled, run it with the following order:

./bin/prac <PLY_file> <PLY_revolution> <face_num>

Where <PLY_file> is the path to the PLY file loaded by assignment 1 and <PLY_revolution> is the path to the PLY file loaded by assignment 2 to generate the surface of revolution with <face_num> number of faces.

Keys

• F1: Shows first assignment.
• F2: Shows second assignment.
• F3: Shows third assignment.
• F4: Shows fourth assignment (default).
• 1: The model is rendered in WIRE mode.
• 2: The model is rendered in SOLID mode.
• 3: The model is rendered in CHESS mode (default mode).
• 4: The model is rendered in POINT mode.
• F: Switches the visualization of the faces normals.
• V: Switches the visualization of the vertices normals.
• Q: Quits the program.

Furthermore, in the third assignment (F3), the following keys are used to manipulate the model:

• Z/z: First degree of freedom control.
• X/x: Second degree of freedom control.
• C/c: Third degree of freedom control.
• B/b: Fourth degree of freedom automatic control.

In the fourth assignment (F4), the illumination is controlled with:

• A/Z: Changes position of white light in the horizonal plane.
• X/C: Changes position of white light in the vertical plane.
