Property ZIndex

ZIndex

Gets or sets the draw order for graphics. Graphics with higher Z-index values are drawn on top of lower Z-index graphics.

Declaration

public int ZIndex { get; set; }

Property Value

Type	Description
Int32	The draw order for graphics. Graphics with higher Z-index values are drawn on top of lower Z-index graphics.

Remarks

A graphic's Z-index is mostly relevant for display in a two dimensional map. For dynamic 3D rendering (in a scene), graphic display order is determined by the distance to the camera rather than by Z-index. Z-index is considered, however, when using static rendering in a scene (draping graphics on the surface, in other words).

If Z-index is not set, graphics will usually render in the order in which they were added to the graphics overlay, the first added is rendered first and subsequent ones on top. In rare cases, the rendering algorithm may change the display order to provide more efficient rendering. If ordering is important, set the Z-index explicitly on graphics. You can also place graphics of the same geometry type in their own graphics overlay and manage the order of the overlays in the MapView or SceneView.

Buffer list: Generate multiple individual buffers or a single unioned buffer around multiple points.

Convex hull: Create a convex hull for a given set of points. The convex hull is a polygon with shortest perimeter that encloses a set of points. As a visual analogy, consider a set of points as nails in a board. The convex hull of the points would be like a rubber band stretched around the outermost nails.

Convex hull list: Generate convex hull polygon(s) from multiple input geometries.

Densify and generalize: A multipart geometry can be densified by adding interpolated points at regular intervals. Generalizing multipart geometry simplifies it while preserving its general shape. Densifying a multipart geometry adds more vertices at regular intervals.
