Vector Gem vs 3D Rotations and Quaternions Usage & Stats
Vector Gem allows the input and three-dimensional display of vectors, lines and planes. The input supports different forms (e.g. linear equation, vector form, normalized form, ...)
Vector Gem can display the starting point, the direction vectors and the normalized vector for each plane and calculate the intersection points with the axes. For lines it can display the starting point and the direction vector and calculate the points of intersection with the coordinate planes.
The color can be selected for each object along with different settings for the display.

“3D Rotations and Quaternions” app helps understand and visualize 3D rotations.
Chapters 1-3
Conversions, algorithms, interactive graphs, and animations of the four standard 3D rotation representations:
1. Euler angles.
2. Axis - angle.
3. Quaternion.
4. Rotation matrix.
The user can define rotation as Euler angles, axis-angle, or Quaternion to convert it to the other representations.
Chapter 4
Data, algorithms, graphs and animations for both linear and spherical interpolation between two quaternions.
Chapter 5
Visualization and data for rotation of user-defined point by user-defined Quaternion.
Chapter 6
Data, calculation algorithm, corresponding matrix, and interactive graph for the quaternion that results in rotation between user-defined vectors v and w.
Chapter 7
Serial rotations with up to 10 quaternions.
Chapter 8
Quaternion calculation based on constant angular velocity and time.
Chapter 9
Reflection of a point across a plane.
Developers hope to get feedback from users at graphmath@aol.com.
