Nyall Dawson	f02602b9bb	[needs-docs] geometry smooth algorithm now also retains and smooths z/m values ... ...instead of just discarding them Applies to processing algorithm and expression function (and QgsGeometry::smooth method)	2018-03-30 08:59:00 +11:00
Nyall Dawson	679797e22b	[FEATURE] New simplify + smoothing expression functions ... Exposes simplification and smoothing algorithms to expression engine, via: - simplify(): applies Douglas-Peucker geometry simplification - simplify_vw(): applies Visvalingam-Whyatt geometry simplification - smooth(): smoothes a geometry Carto tip: use smooth along with geometry generators to minimise the typical "GIS" noded look of rendered geometries!	2016-09-03 21:52:06 +10:00
