👉 Arm math, also known as armature math, is a fundamental concept in animation and motion graphics that deals with the mathematical relationships between the positions, rotations, and transformations of an object's arm or body segments. It involves understanding how to interpolate between key poses (positions, rotations, and scales) to create smooth and natural movements. This is achieved through various mathematical operations such as linear interpolation (lerp) for positions, spherical linear interpolation (slerp) for rotations, and affine transformations for scaling and translation. Arm math also incorporates concepts like quaternions for efficient rotation interpolation, ensuring that animations are not only visually appealing but also computationally efficient. By mastering arm math, animators can create fluid and realistic movements that enhance the overall quality of their work.
