Simple Animation Graph brings traditional 2D animation timing techniques into the 3D viewport. Using Blender's built-in Annotate tool, users can draw paths and timing spacings directly on the screen to control object and armature movement.

The tool features two primary modes: Pose-to-pose for interpolating between keyframes across armatures or object groups, and Follow Trajectory for mapping position and rotation along hand-drawn paths. By drawing intersections along the annotation stroke, the add-on automatically generates keyframes that match the visual spacing, allowing for intuitive visual control over easing and timing.
