Detailed Description

Defines the path that a tubular or extruded shape follows in 3D space.
The parametric parameter 't' defines a position along the path where t=0 is the start and t=1 the end of the shape.

Values of outside the range ≥0 and ≤1 are not on the path and need not be defined in any class implementing this interface.

The attribute nbrSlices does not affect the shape or the path, it only affects the level of detail in shapes using the path.

Parameters
nbrSlices

Member Function Documentation

boolean shapes3d.path.AbstractPath.isOpenPath ( )
Returns
false if the path forms a closed loop, else true

Implements shapes3d.path.Path.

int shapes3d.path.AbstractPath.nbrSlices ( )
Returns
the number of slices to use in this path

Implements shapes3d.path.Path.

PVector shapes3d.path.AbstractPath.orthogonal ( float  t)

If you don't provide an implementation in the child class this version will attempt to find a solution that minimizes twist along the path.

Parameters
t≥0 and ≤1.0
Returns
a PVector giving the x,y,z coordinates of the tangent orthogonal at position t

Implements shapes3d.path.Path.

abstract PVector shapes3d.path.AbstractPath.point ( float  t)
pure virtual

Get the position along the path.

Parameters
t≥0 and ≤1.0
Returns
a PVector giving the x,y,z coordinates at a position t

Implements shapes3d.path.Path.

Implemented in shapes3d.path.BCurve2D, shapes3d.path.BCurve3D, shapes3d.path.BSpline3D, shapes3d.path.BSpline2D, shapes3d.path.Lissajous, shapes3d.path.Spiral, shapes3d.path.Linear, and shapes3d.path.Ring.

PVector shapes3d.path.AbstractPath.tangent ( float  t)

Get the normalised tangent to the path.

Parameters
t≥0 and ≤1.0
Returns
a PVector giving the x,y,z coordinates of the tangent at position t

Implements shapes3d.path.Path.
