RenderPipelineApp vs 3D Rotations and Quaternions

This is a interactive tutorial about basic rendering pipelines. We will explore some abstract mathematical concepts within the render pipeline through intuitive operations. Later on, we will extend the theory of 3D rendering to 4D using `ARKit` and take a glimpse into high-dimensional geometry, which can provide you with a brand new experience. Although they may have a novel visual style, their underlying logic remains similar. I aim to make interactive teaching accessible and memorable by utilizing Swift, `SceneKit`, and `ARKit`. Hope you have fun here!

3D Rotations and Quaternions is an interactive tool for users who work with 3D orientation math in graphics, roboticsor simulation. It provides precise computations, clean visualizations, and fast conversions between the standard rotation representations. Features include: • Conversion between Euler angles, axis–angle, quaternions, and rotation matrices • Interactive 3D visualization and rotation animation • Quaternion interpolation (LERP and SLERP) • Rotation of user-defined points by user-defined quaternions • Determination of a quaternion that rotates vector v into vector w • Composition of up to 10 sequential quaternion rotations • Quaternion generation from constant angular velocity and time • Reflection of a point across a plane Feedback and suggestions: graphmath@aol.com
