helix
Transformation along helical lines.
Signatures
- helix( vector axis, float angle )
- helix( vector onset, vector axis, float angle )
Details
The helix transformation is a space point transformation that rotates all space points around a given axis. The amount of the rotation, i.e. the rotation angle changes linearly with the points's position along the axis, what results in a helical twisting.
Example
document.render_vis_smooth = true
make helix( <[0.5, 0.5, 1.0]>, <[0.0, 0.0, 1.0]>, PI/2.0 ) >>
subdiv( 0.05, <[0.0, 0.0, 1.0]> ) >> box()
Result of the example: helix transformation on a subdivided box.
Casts To
Parameters
- axis
-
Vector pointing into the helix direction.
- angle
-
Defines the angle of rotation (in rad) along vector axis. Positive values follow a right-handed helix, negative values a left-handed one.
- onset
-
A space point that acts as onset of the axis and thus as origin of the helix transformation.
