Visual MATH 4D Lite vs 3D Rotations and Quaternions

Visual MATH 4D Lite is a graphical calculator and lets you visualize your mathematical equations in 2D, 3D and 4D with animated graphs. It supports multiple types of equations like cartesian, polar, spherical and parametrical graphs. Features: - support for vectors and matrices - support for trigonometrical functions - support for complex numbers - support for complex graphs (draw real part & imaginary part) - support for cartesian graphs like f(x) and f(x,y) - support for polar graphs - support for spherical graphs - support for parametrical graphs - support for n-th derivations - support for definite integrals - support for sum, product, round like floor and ceil - support for constants - support for sharing content - gesture support for scaling and rotating graphs - support for graph animations - support for multiple graphs - support for graph legends - and more ...

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
