Filter the point cloud for two different ranges on same field.
I am looking to filter Filed 'X' and obtain the points that only lie in the
range [-8 -0.15] U [0.15 8]. Some thing like filtering the range that lie in
two concentric circles. How can i do that ? or is the way that i can create
my own filter such that (x>0.15 && x<8) || (x<-0.15 && x>-8)
Since my point cloud is obtained from Lidar data (LaserScan messges), it
contain both negative and positive values.
