Interpolacjatweening

Interpolacjatweening is a term used in computer graphics to describe the generation of in-between frames by blending interpolation techniques with traditional tweening. The coinage appears to merge interpolation and tweening and is used to describe methods that fill gaps between keyframes with coherent motion and shape changes. It is not a formal standard in major reference works, but it appears in discussions among animators and in some technical forums as a flexible umbrella for several approaches.

In a typical workflow, keyframes specify start and end states for objects. Interpolacjatweening computes intermediate frames by interpolating parameters such as position, orientation, scale, and, when relevant, morph targets or deformation fields. Methods include linear, spherical, and cubic interpolation, often with easing curves to control speed. Some approaches enforce constraints to preserve physical plausibility or silhouette consistency across frames.

More advanced variants use optical flow or learning-based models to predict plausible in-between motion. Hybrid approaches mix deterministic interpolation with learned refinements to balance control and automation, aiming to reduce artifacts while preserving artistic intent.

Applications span 2D and 3D animation, game development, and visual effects. Advantages include smoother motion and reduced manual keyframing; drawbacks include potential artifacts in complex scenes and the need for artist oversight to maintain style and coherence.
