详细描述

Minimal observable contract for physics simulation providers.

The backend borrows domain-owned state and must be destroyed before that state. Implementations own no graphics or presentation resources. Calls are simulation-thread affine and must not run concurrently with another mutation of the same domain state. A failed step leaves observation and domain state unchanged.

在文件 SimulationBackend.h 第 158 行定义.

构造及析构函数说明

~ISimulationBackend()

virtual eve::physics::ISimulationBackend::~ISimulationBackend ( )

virtualdefault

Releases the backend; borrowed domain state is not destroyed.

成员函数说明

determinism()

virtual SimulationDeterminism eve::physics::ISimulationBackend::determinism ( ) const

pure virtualnoexcept

Returns the provider's replay/determinism guarantee.

返回

The declared determinism level.

在 eve::fluids::FluidSimulator, eve::physics::Cloth, eve::physics::Cloth3D, eve::physics::ClothGPU, eve::physics::Rope3D , 以及 eve::physics::SoftBody3D 内被实现.

kind()

virtual SimulationBackendKind eve::physics::ISimulationBackend::kind ( ) const

pure virtualnoexcept

Identifies the provider family.

返回

CPU, GPU, or a named test accelerator.

在 eve::fluids::FluidSimulator, eve::physics::Cloth, eve::physics::Cloth3D, eve::physics::ClothGPU, eve::physics::Rope3D , 以及 eve::physics::SoftBody3D 内被实现.

observation()

virtual SimulationObservation eve::physics::ISimulationBackend::observation ( ) const

pure virtualnoexcept

Returns completed-step observables by value.

返回

A snapshot that remains valid after the backend changes.

在 eve::fluids::FluidSimulator, eve::physics::Cloth, eve::physics::Cloth3D, eve::physics::ClothGPU, eve::physics::Rope3D , 以及 eve::physics::SoftBody3D 内被实现.

restoreObservation()

virtual eve::Result< void > eve::physics::ISimulationBackend::restoreObservation ( const SimulationObservation &  )

inlinevirtual

Restores progress metadata after the owner restores its state.

参数

observation

Completed-step observation to install.

返回

Applied when supported, or Unsupported when the backend cannot restore metadata without rebuilding its state.

备注

This operation changes only backend-owned progress metadata; callers must restore the domain state atomically as one unit.

Failure.

被 eve::fluids::FluidSimulator, eve::physics::Cloth, eve::physics::Cloth3D, eve::physics::ClothGPU, eve::physics::Rope3D , 以及 eve::physics::SoftBody3D 重载.

在文件 SimulationBackend.h 第 200 行定义.

引用了 eve::Diagnostic::error(), eve::Result< T >::failure() , 以及 eve::Unsupported.

step()

virtual eve::Result< void > eve::physics::ISimulationBackend::step ( const eve::SimulationStep &  step, const SimulationSettings &  settings  )

pure virtual

Advances the borrowed solver state by one checked fixed step.

参数

step	Injected tick and duration; tick must increase strictly.
settings	Solver policy for this step.

返回

Applied with updated state, or a structured rejection/failure.

在 eve::fluids::FluidSimulator, eve::physics::Cloth, eve::physics::Cloth3D, eve::physics::ClothGPU, eve::physics::Rope3D , 以及 eve::physics::SoftBody3D 内被实现.
