## ◆ PerformUnitTests()

| private

## ◆ PickRandomPositions()

void GuidewireSim.UnitTest_SolveStretchConstraint.PickRandomPositions | ( | out Vector3 | particlePositionOne,
|  | out Vector3 | particlePositionTwo
| ) |  |
| private

Picks the first particle position uniformly distributed with \( x,y,z \in [-5, 5] \) and the second uniformly distributed around the first position with a uniformly distributed distance in \( [rodElementLength - maximalDistanceOffset, rodElementLength + maximalDistanceOffset] \).

Note
  The method for picking the second position is inspired by https://math.stackexchange.com/q/50482

Requirements:

  Picks the first particle position uniformly distributed so that \( x,y,z \in [-5, 5] \).

  Picks a distance between the two particles that is uniformly distributed in the interval \( [rodElementLength - maximalDistanceOffset, rodElementLength + maximalDistanceOffset] \).

  Picks the second particle position uniformly distributed on the surface of the sphere with center `particlePositionOne` and radius `startDistance`.

## ◆ Start()

## Member Data Documentation

## ◆ constraintSolvingStep

ConstraintSolvingStep GuidewireSim.UnitTest_SolveStretchConstraint.constraintSolvingStep
| private

The component ConstraintSolvingStep that is responsible for correcting the predictions with the collision and model constraints.

## ◆ executeUnitTest

bool GuidewireSim.UnitTest_SolveStretchConstraint.executeUnitTest = false
| private

Whether or not to perform all unit tests of this script.

## ◆ mathHelper

MathHelper GuidewireSim.UnitTest_SolveStretchConstraint.mathHelper
| private

The component MathHelper that provides math related helper functions.

## ◆ rodElementLength

float GuidewireSim.UnitTest_SolveStretchConstraint.rodElementLength = 10f
| private

## ◆ sampleSize

int GuidewireSim.UnitTest_SolveStretchConstraint.sampleSize = 10
| private

The number of value-pairs the test is executed with. E.g. if sampleSize is 10, then the unit test is executed with 10 randomly drawn value-pairs. A higher number needs more time to execute.
