PDT Trigonometrical Waves

The Menu for Trigonometrical Waves

This section of PDT is used to generate Trigonometrical Waves in a selected Object. In order to enable the Generate 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 Wave Form - Sine Cosine, or Tangent.

• The number of Cycles - each cycle is 180 degrees, NOT a full circle, so a value of 1 will result in one peak with a sine wave for example.

• The Cycle Length - the length in blend file units of one cycle.

• The Amplitude - the height of the wave.

• Whether to Empty the target object, set to true this will delete all vertices in the target object.

• 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.

• The Start Location - the point at which the first vertex will appear in Global Coordinates.

• Whether Absolute 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:
