How to Use it?

See a two-minute demo of an early version of Motiongen in Dr. Purwar's TEDx talk

Four-bar Linkage Synthesis:

Four-bar Linkage Simulation:

App Settings and Features:

Controls

 Synthesis Menu:

	Poses - Input and edit poses. Enter 3 poses with 2 fixed-pivot constraints, 4 poses with 1 fixed-line constraint, or 5 or more poses with no other constraints.
	Fixed-Line Constraint - Draw a fixed line on which fixed pivots should lie for four-position synthesis.
	Fixed-Point Constraint - Place two fixed pivots for three-position synthesis.
	5 Arbitrary Poses - Synthesizes a linkage based on five random poses.
	4 Arbitrary Poses - Synthesizes a linkage based on four random poses and a fixed pivot-line constraint.

 

Simulation Menu

	RR Dyad - Touch and drag to draw an RR dyad.
	PR Dyad - Touch and drag to draw a PR dyad.
	RP Dyad - Touch and drag to draw an RP dyad.
	Change Crank - Switch the driving dyad.
	Change Branch - Switch the configuration to move the coupler to the other circuit.
	Change Configuration - Switch the coupler to the other branch of the circuit.

 

Animation Menu

	Play - Play/Pause the linkage animation.
	Stop - Stop the linkage animation and reset the coupler.
	Timeline - Show the animation timeline. Drag the slider to see the linkage throughout the animation.
	Capture Poses - Capture the current coupler position. Captured poses can be used to synthesize new linkage solutions from the Menu icon at the top left.

Visualization Menu

	Camera - Open the camera to take a picture to use as the background for the workspace. The slider controls the opacity of the background image.
	Load Image - Load an image to use as the background for the workspace. The slider controls the opacity of the background image.
	Clear Image - Clear the background image.

Menu Options

	Menu - Open the side menu. The side menu contains examples, and allows the synthesis of linkages from captured poses.
	Home - Opens the home screen. The home screen displays all your files and allows you to create new files and delete old ones.
	New - Create a new file. The old file will be saved and can be found on the home screen.
	Export - Export your linkage to a PDF or XML format. The exported file displays information about your linkage.
	Reset View - Reset the view to focus on the workspace.
	Undo - Undo the previous operation.
	Redo - Redo the last undone operation.
	Delete - Delete the selected element. If no element is selected, the entire linkage will be deleted (this cannot be undone!).
