streamline3d

Built-in command

Arguments:

• x[%],y[%],z[%],_L>=0,_dl>0,_interpolation,_is_backward={ 0 | 1 },_is_oriented={ 0 | 1 }    or
• 'formula',x,y,z,_L>=0,_dl>0,_interpolation,_is_backward={ 0 | 1 },_is_oriented={ 0 | 1 }

Description:

Extract 3D streamlines from selected vector fields or from specified formula.

interpolation can be { 0:nearest integer | 1:1st-order | 2:2nd-order | 3:4th-order }.

Default values:

dl=0.1, interpolation=2, is_backward=0 and is_oriented=0.
