Delete FIRST and LAST point of line geometry

[Sunsheku 0]

Hello.

I'm trying to delete first point and last point of geometry made with line node.

Somebody have a solution for this?

Hi,

many ways to do that... here is one:

make a "group by range" node, choose points as a group type, and put 0 for start, 1 for end, and check inverse range. This will select the last point.

make another group, with point 0.

blast those 2 groups.

 

a shorter way would be a wrangler:

put down a point wrangler node.

and type this :

removepoint(0,0);
if(@ptnum == (@numpt-1))
    removepoint(0,@ptnum);

first line remove point 0 (the first point of the line). (0,0)means : (geometry entering slot number 0 of the node , point number 0)

second line reads : if the actual point number is equal to the number of points minus one (the last point of the line)

third line : remove that point

//set a wrangle to run over primitives
int primpts[] = primpoints(0,@primnum);
removepoint(0,primpts[0]);
removepoint(0,primpts[-1]);
