\"guitar_designer_screenshot_main_screen\"<\/a>Guitar Designer is a simple app to help with the design of guitar body shapes. It represents the outline of a guitar body by a smooth curve controlled by a set of “control points” whose positions determine the shape of the curve:\u00a0 the control points define a broken line called the “control polygon”, with the guitar outline being a smoothed version of the polygon that passes through its endpoints. The shape of the curve can be refined by moving, adding and deleting control points by touching the diagram on the screen.<\/p>\n

Startup<\/h2>\n

On first startup, the app displays an empty grid with soundhole and outline, and is in “New Design” mode. Touch the screen to specify the positions of the control points that will determine the design, then click the “Done” button or menu item when finished.<\/p>\n

The initial settings are for a symmetric design, so two mirror-image curves will be drawn for just one set of control points. This behavior can be changed through a setting in the “Options” menu.<\/p>\n

Design Refining<\/h2>\n

Touch the diagram to select and move control points to refine the design. As the control points are moved, the design will change shape to reflect the new positions.<\/p>\n

You’ll quickly notice a couple of things about the design curve relative to the control points:<\/p>\n
