Curve Tessellation

Customization ›› Geometry ››

Feature data providers that do not support circular arcs create segmented lines to simulate the curves of an arc. This is called tessellation. The degree of tessellation determines how accurate the displayed curve will be (how close it will approximate the mathematical “true” curve) and how much performance overhead is required to generate the graphics for a curve. You can specify the arc-chord distance, which determines the density of the segmented lines for such providers. The lower the arc segmentation value, the more line segments are used to create the arc (which makes the arc more precise).
