类
class	eve::gpgpu::EcsGpuWorkspace< Comp >
	Reusable typed CPU staging for a GPU ECS component stream. Ownership stays with the caller; one workspace must not be used concurrently. 更多...

命名空间
namespace	eve
	Build metadata (engine git commit, build time, third-party version).
namespace	eve::gpgpu
	Fluids module — interactive surface fluid simulation.

函数
template<typename Comp >
constexpr int	eve::gpgpu::componentFloatCount ()
	Component float count.
template<typename Base , typename Comp >
int	eve::gpgpu::countViewEntities ()
	Count live entities matching View<Base, Comp>.
template<typename Base , typename Comp >
int	eve::gpgpu::packViewComponent (ShaderSystem &sys, int binding, EcsGpuWorkspace< Comp > &workspace)
	Pack View<Base, Comp> into ShaderSystem binding as AoS floats. Returns entity count (0 if empty).
template<typename Base , typename Comp >
int	eve::gpgpu::packViewComponent (ShaderSystem &sys, int binding)
	Compatibility overload that uses a temporary staging workspace.
template<typename Base , typename Comp >
void	eve::gpgpu::unpackViewComponent (ShaderSystem &sys, int binding, int count, EcsGpuWorkspace< Comp > &workspace)
	Write ShaderSystem binding floats back into View<Base, Comp> (same order as pack). count should be the value returned by packViewComponent.
template<typename Base , typename Comp >
void	eve::gpgpu::unpackViewComponent (ShaderSystem &sys, int binding, int count)
	Compatibility overload that uses a temporary staging workspace.
template<typename Base , typename Comp >
int	eve::gpgpu::packViewComponentRange (ShaderSystem &sys, int binding, int firstEntity, int entityCount, EcsGpuWorkspace< Comp > &workspace)
	Pack a stable contiguous View range into an existing resident buffer. The full buffer must have been allocated by a prior full pack/ensureBuffer.
template<typename Base , typename Comp >
int	eve::gpgpu::unpackViewComponentRange (ShaderSystem &sys, int binding, int firstEntity, int entityCount, EcsGpuWorkspace< Comp > &workspace)
	Unpack a stable contiguous resident-buffer range into a matching View range.
template<typename Base , typename Comp >
int	eve::gpgpu::runViewComponentSystem (ShaderSystem &sys, int binding, float dt)
	Pack + dispatch + unpack a single-component GPU system. Additional bindings must be uploaded by the caller before this helper, or use ShaderSystem manually for multi-buffer systems.
