Segment Editor : Segment-Range 

The Segment Range separator is available with many (not all) Traditional Motion-Laws.

Parameters:

Start-Range: default = 0

End-Range: default = 1

The Segment-Range parameters control the phases at which to start and end the mathematical-function of the motion-law.

One application of Segment-Range the parameters is to design Asymmetrical Motions - see below.

Default Segment Ranges

Default Segment Ranges

Start-Range ≥ 0

End-Range ≤ 1

0 ≤ Start Range < End Range ≤ 1

Start-Range and End-Range parameters do NOT change the Segment-Width.

Example:

The images below show the acceleration graph of a Modified Sinusoid motion-law with different Segment-Range parameter values.

Note: the Segment-Width does not change when you edit the Segment-Range parameter.

1) Standard Mod Sine

1) Standard Mod Sine

STANDARD Modified Sinusoid.

Segment-Width = 120º-30º = 90º

Start-Range = 0.0

End-Range = 1.0

2) Start Range = 0.2 ; End-Range = 1

2) Start Range = 0.2 ; End-Range = 1

Modified-Sinusoid with 20% clipped from its Start.

Segment-Width = 120º-30º = 90º

Start-Range = 0.2 - to remove 20% from the start of the Modified-Sinusoid mathematical function

End-Range = 1.0

Start Range = 0.0 ; End-Range = 0.8

Start Range = 0.0 ; End-Range = 0.8

Modified-Sinusoid with 20% clipped from its End.

Segment-Width = 120º-30º = 90º

Start-Range = 0.0

End-Range = 0.8 - to remove the 20% from the end of the Modified-Sinusoid mathematical function

Asymmetric Motion - Example

For example: use an Asymmetric Modified-Sinusoid to accelerate rapidly and decelerate more gradually, or vice versa.

You split a symmetric Modified-Sinusoid segment into two segments, and then use the Segment-Range parameters to change the phase of the crossover to design the Asymmetric Modified-Sinusoid.


In the image below there is a Rise and Return motion.

The Rise is an Asymmetric Modified Sinusoid (0 - 180º). The crossover is at 60º.

The Return is a Symmetric Modified Sinusoid (180 - 360º). The crossover is at 270º.
