pure virtual

The entry point for the constraint solver.

Parameters

[in]	dt	The simulation time-step
[in]	continuation	The continuation task for the solver
[in]	processLostTouchTask	The task that processes lost touches

This method is called after the island generation has completed. Its main responsibilities are: (1) Reserving the solver body pools (2) Initializing the static and kinematic solver bodies, which are shared resources between islands. (3) Construct the solver task chains for each island

Each island is solved as an independent solver task chain. In addition, large islands may be solved using multiple parallel tasks. Island solving is asynchronous. Once all islands have been solved, the continuation task will be called.

Implemented in physx::Dy::DynamicsContext, and physx::Dy::DynamicsTGSContext.

◆ updateBodyCore()

virtual void physx::Dy::Context::updateBodyCore ( PxBaseTask * continuation )

pure virtual

This method copy gpu solver body data to cpu body core.

Implemented in physx::Dy::DynamicsContext, and physx::Dy::DynamicsTGSContext.
