Detailed Description

Global simulator settings.

Member Data Documentation

bool ODESimulatorSettings::adaptiveTimeStepping

If true, difficult collision situations are resolved using new adaptive time stepping methods (default true)

double ODESimulatorSettings::clusterNormalScale

During contact clustering, the metric for determining "nearby" contacts uses this weight to scale distances in normal space. Distance in position space have weight 1. (default 0.1)

double ODESimulatorSettings::instabilityConstantEnergyThreshold

If kinetic energy grows too much from step to step, instability correction is triggered. Specifically it turns on if KE[t+1] > instabilityLinearEnergyThreshold*KE[t]+instabilityConstantEnergyThreshold KE[t+1] > instabilityMaxEnergyThreshold for any object. Default values are 1, 1.5, and 100000.

double ODESimulatorSettings::instabilityPostCorrectionEnergy

The kinetic energy threshold enforced for any body going unstable. negative values -c means scale current kinetic energy by c. 0 means set velocity to 0. Positive values are constants * threshold. (default -0.9)

int ODESimulatorSettings::maxContacts

Maximum number of contacts between each pair of objects after clustering. Larger values slow down collision detection (default 20)
