Detailed Description

Implementation of the ISolver interface.

When enabled, it runs the simulation on all its cloths and sends notifications before and after the simulation has been executed.

Member Function Documentation

◆ Enable()

void NvCloth::Solver::Enable ( bool  value)
overridevirtual

Enable or disable running simulation on the solver. When the solver is disabled it won't run simulation and its events will not be signaled.

Implements NvCloth::ISolver.

◆ FinishSimulation()

void NvCloth::Solver::FinishSimulation ( )
overridevirtual

Complete the simulation process. If the solver is in user-simulated mode the user is responsible for calling this function. Note: This is a blocking call that will wait for the simulation jobs to complete.

Implements NvCloth::ISolver.

◆ SetInterCollisionDistance()

void NvCloth::Solver::SetInterCollisionDistance ( float  distance)
overridevirtual

Specifies the distance (meters) that cloths' particles need to be separated from each other. Inter-collision refers to collisions between different cloth instances in the solver, do not confuse with self-collision, which is available per cloth through IClothConfigurator. When distance is 0 inter-collision is disabled (default).

Note
Using inter-collision with more than 32 cloths added to the solver will cause undefined behavior.

Implements NvCloth::ISolver.

◆ SetInterCollisionIterations()

void NvCloth::Solver::SetInterCollisionIterations ( AZ::u32  iterations)
overridevirtual

Sets the number of iterations the solver will do during inter-collision. Default value is 1.

Implements NvCloth::ISolver.

◆ SetInterCollisionStiffness()

void NvCloth::Solver::SetInterCollisionStiffness ( float  stiffness)
overridevirtual

Sets the stiffness for inter-collision constraints. Stiffness range is [0.0, 1.0]. Default value is 1.0.

Implements NvCloth::ISolver.

◆ SetUserSimulated()

void NvCloth::Solver::SetUserSimulated ( bool  value)
overridevirtual

Set the solver into user-simulated mode. When the solver is user-simulated the user will be responsible to call StartSimulation and FinishSimulation functions, otherwise they will be called by the cloth system.

Implements NvCloth::ISolver.

◆ StartSimulation()

void NvCloth::Solver::StartSimulation ( float  deltaTime)
overridevirtual

Start simulation of all the cloths that are part of this solver. This will setup and start cloth simulation jobs. If the solver is in user-simulated mode the user is responsible for calling this function. Note: This is a non-blocking call.

Implements NvCloth::ISolver.
