PDT Trigonometrical Waves

This section of PDT is used to generate Trigonometrical Waves in a selected Object. In order to enable the button, the use must first select an object using the Object Selector box.

There are then a number of parameters that need to be set:

• The Working Plane - this is just a duplicate display of the main PDT Working Plane.

• The - Sine Cosine, or Tangent.

• The Amplitude - the height of the wave.

• The Resolution - the number of vertices on one cycle.

• If you are generating a Tangent wave, the maximum amplitude of the wave. Tangent functions range from 0 to infinity over a 90 degree wave, so this limits the extent to which the tangent wave will extend.

• Whether values are required. In this context Absolute means greater than 0, so all peaks will be positive.

And here is an “After” image:

Here is an example of “Absolute” values using a Sine Wave:

And finally an example of a Tangent Wave limited to a maximum value of 5:
