[Visualpython-users] bug in vpython path library

________________________________




 
I am using the extrusion
object library, path library of Vpyhon for my project. my program simply
extracts or parses G-codes with X,Y, Z coordinates, the program then uses this
extracted points as my path, a 2D square shape is then extruded through these points
or path in that sequence.
the problem is, these
points are line segments, where a line segment is define by two points i.e
X1,Y1,Z1 and X2,Y2,Z2. Now if the third point X3,Y3Z3 is sharp turn, i.e the
angle between the line segment becomes > 270, the extrusion generates very
long spikes or glitches which makes my work messy. my G-codes are all accurate,
because it is tested. this is a special case where the preceding point makes
that sharp turn. i showed it to some programmers and they say it might be a bug
with vpython extrusion library. i can share my program with you, or pictures of
what i mean. hope i get a response from you. thanks
