Quaternion Rotation Visualization

This program demonstrates a 3D visualization of quaternion rotation using OpenGL. The rotation is applied to a wireframe teapot, and the user can interactively change the viewing angle and teapot position.

Dependencies

Ensure that you have the following dependencies installed:

  • OpenGL
  • GLUT (OpenGL Utility Toolkit)

Installation

To install the necessary OpenGL and GLUT libraries, follow these steps:

  1. Open Visual Studio

    • Launch Visual Studio.

  2. Open NuGet Package Manager

    • In the Visual Studio toolbar, click on Tools.

  3. Open Package Manager Console

    • From the dropdown menu, select NuGet Package Manager.
    • Then choose Package Manager Console from the submenu.

  4. Install OpenGL and GLUT

    • In the Package Manager Console, type the following command and press Enter: 
      Install-Package nupengl.core

Usage

Once the program is running, you can interact with the visualization using the following keyboard controls:

Viewing Angle Adjustment

  • 'W' or 'w': Move the eye position up
  • 'S' or 's': Move the eye position down
  • 'A' or 'a': Move the eye position left
  • 'D' or 'd': Move the eye position right
  • 'Q' or 'q': Move the eye position closer
  • 'E' or 'e': Move the eye position farther

Teapot Position Adjustment

  • 'I' or 'i': Move the teapot upward
  • 'K' or 'k': Move the teapot downward
  • 'L' or 'l': Move the teapot right
  • 'J' or 'j': Move the teapot left
  • 'O' or 'o': Move the teapot forward
  • 'U' or 'u': Move the teapot backward

Rotation Axis Adjustment (Special Keys)

  • Arrow keys: Adjust the rotation axis (up, down, left, right)
  • Page Up: Increase rotation axis depth
  • Page Down: Decrease rotation axis depth

Quaternion Operations

Quaternion operations are tested and displayed in the console when the program is executed. The operations include quaternion length calculation, normalization, conjugation, and inversion.

Notes

  • The program uses a quaternion-based rotation to smoothly rotate the teapot.
  • Information about the viewing angle, rotation axis, eye position, and teapot position is displayed on the screen.
