Hi Kazuyoshi,
I do not think the glyph filter will do what you want it to. You might use a
Python programmable filter[1] to turn each point into a line segment (i.e., a
line from (x,y,z) to (x+dx, y+dy, z+dz)). Then run "Cell Centers" on the
resulting line segment data and add oriented, unscaled cone glyphs at each cell
center to indicate the direction along the line segments. That would draw lines
along the path plus cones pointing along the direction of the path.
