Hello. Sorry for being so slow, got lots of work with reports... Just tried Mandelbrot filter applied to a slice. With defaults, it created a kind of fractal rotated and translated relative to original slice. Should I use some particular settings to just resample? Also, tried Wavelet and Gaussian resample. These filters create volumes being appliet to the slice so it seems that they doesnt fit my needs. Any suggestions? Is there some simple filter to resample arbitrary surface in ParaView. Thanks for your attention. (Now I use Mask Points with the same problem of un-even point distribution, the best results are with Random sampling + randomised ID strides, but without limiting the maximum number of points; instead of this limit I preview points with glyphs and then feed these point to the Stream tracer with custom source)
