Curve Editor Background Images


A background image may be inserted in the plot area in the Curve Editor to serve as a guide to the overlaid curve and control points. Activate the “Image” button to browse for an image file and then scale or fit the background as needed. If a background image is shown from an opposite view than OpenVSP’s convention, where U_0 starts on the right side of the plot and right side of the body, then the image may be flipped across the plotter Y axis.

Once a background image has been placed such that the desired width and height scaling fits the image, the background may be locked to the curve display using the “Lock Image” button. Once locked, the background and curve plot will zoom and pan in sync, enabling the user to closely focus on fitting corners and blends without sacrificing overall visibility.
