Hello dear devs.
I have polyline objects defined as :
positions: Cesium.Cartesian3.fromDegreesArray( points ),
material: new Cesium.PolylineOutlineMaterialProperty(
color: color.withAlpha( 0.6 ),
outlineColor: Cesium.Color.BLACK.withAlpha( 0.40 )
and I would love if this can be interpolated somehow.
- is there a way to do so ?
@Yordan_Yanakiev1 It depends what you’re trying to accomplish. The Cesium library does have a few interpolation algorithms: HermitePolynomialApproximation - Cesium Documentation LagrangePolynomialApproximation - Cesium Documentation
There isn’t a way to automatically apply these to your polyline via the Entity API, but you can use those algorithms to pre-compute your positions array. The Entity API does however have built-in support interpolation for
position property used to draw a
path. See Cesium Sandcastle
Hey Hannah !
Thank You for Your reply.
Well… I just have a polylines which is updated each couple of seconds, and I would like to have interpolation on them. to be more… smooth in some way.
