3D Object Motion Simulator

Build a small 3D scene, transform objects, and preview movement or recorded keyframes in the browser.

What this tool does

3D Object Motion Simulator is an interactive scene for adding basic 3D shapes and experimenting with motion. Create cubes, spheres, cones, cylinders, polyhedra, toruses, planes, rings, and torus knots, then select objects to change their names, positions, rotations, and scale.

Each object can have active translate or rotate movements. You can also record transform keyframes while dragging the gizmo, play the result, and scrub its timeline. A perspective scene, small orthographic view, and camera navigation make it easier to inspect the result from different angles.

Who this is for

• Students and beginners learning 3D transforms, axes, and animation timing
• Designers and developers blocking out motion ideas before implementing them elsewhere
• Anyone who wants a lightweight browser sandbox for shape placement and keyframe experiments

How to use this tool

1. Choose Add Object, select a shape, and click an object or Select Object to make it active.
2. Use Move (T), Rotate (R), or Scale (S) and drag the transform gizmo. The Top, Front, and Side buttons change the orthographic preview.
3. Choose Movement (M) to add a continuous translate or rotate movement, then set its axis and speed in the object properties dialog.
4. Choose Record, transform the selected object to capture keyframes, then stop recording and use Play or the timeline slider to preview it.
5. Open Help for mouse, touch, and keyboard shortcuts. Use Reset View to restore the camera.

Inputs

Inputs include a selected primitive shape, object name, position, rotation, scale, movement type, axis, speed, and transform-gizmo actions. Camera orbit, pan, zoom, orthographic view buttons, and recorded timeline positions control how you inspect the scene.

Outputs

The output is a live 3D scene with movable objects, active movement arrows, and an in-browser animation preview. Recorded keyframes can be played or scrubbed while the page is open. This page does not include a 3D model, video, or project-file export action.

Example use cases

• Prototype the timing and direction of a rotating or translating object
• Practice the difference between position, rotation, scale, and world/local axes
• Storyboard a simple 3D interaction before rebuilding it in a full scene editor
