refined the workbench to cope with more complex forms.

At resolution of 50 all 100 points are inside in 1 go!

@venu

this will prevent you having to do lots of iterations when using complex shapes:random-point-in-polygons.fmw

No iteration, just setting high enough resolution in grid builder...

There already seems to be a custom transformer on FME Hub (by @takashi, unsurprisingly) that might be helpful here.

A possible solution could include

  • Cloner to create multiple features, e.g. 121 Sand features for block A.
  • BoundsExtractor to get min/max X/Y values for the polygon
  • Two RandomNumberGenerators to generate min/max X/Y values inside the bounds and a VertexCreator to create a point based on those values
  • SpatialFilter to check if random point is inside (if not, loop) if the blocks aren't perfectly rectangular and oriented north/south
