MeshTransform

The MeshTransform class provides functionality for defining and manipulating transformations applied to a 3D mesh over time. It supports transformations such as translation, rotation, scale, and morphing, allowing each transformation to be set and retrieved for specific time intervals. The class includes methods for managing keyframes for each type of transformation, enabling smooth animation and interpolation of transformations between time points.
