Trajectory Anim

Blender add-on to quickly animate by drawing trajectory line.

Similar to Follow Path constraints, you can animate an object by drawing a trajectory line, but much more convenient and faster than using the constraints. Aside from following and/or rotating along the path, you can also draw trajectory line to represent rotation. Not only that, but you can also draw intersection line in your trajectory line to represent timing chart, which give better control over timing/easing.

    Timing Chart

Features

  • Timing Chart: Similar to Timing Chart, you can draw intersection line that will act as a timing. Starting and ending points is not required to be intersected
  • Multi Target: You can apply position/rotation to as many objects/bones as you want
  • Global/Local Orientation: You can choose whether you want to move or rotate the object through global axis, or local axis
  • Relativity: You can choose whether you want snap along the path, or relative to its current position
  • Rotate Along Path: Similar to using Follow Curve, this will cause object to rotate along the path
  • Automatic Tracking: Track axis and up axis are determined automatically based off the given path, you can also manually input your own track axis and up axis
  • Timings: You can set the duration to your liking, or even add step frame to skip every x frames
  • Stroke Operators: Many operator to quickly tweak your strokes
  • Layers: No need to draw everything using single layer, you can use layers and script will only animate from strokes belonging to the active layer
  • Supports Many Types: From annotation, grease pencil, or even curve object
