One-draw particle shadow caster matching Fluid3D ShadowmapExposer behavior. @ownership Borrows Graphics for its lifetime and owns one Graphics-managed dynamic mesh. @thread Construction, update and destruction are render-thread affine. @reentrancy Invokes no script callbacks; destruction must occur outside shadow traversal.

构造及析构函数说明

◆ VolumeFluidShadowCaster() [1/2]

eve::fluids::VolumeFluidShadowCaster::VolumeFluidShadowCaster ( graphics::Graphics & graphics )

explicit

Constructs a VolumeFluidShadowCaster.

参数

graphics Initialized backend that must outlive this caster.

在文件 VolumeFluidShadowCaster.cpp 第 17 行定义.

◆ ~VolumeFluidShadowCaster()

eve::fluids::VolumeFluidShadowCaster::~VolumeFluidShadowCaster ( )

Releases VolumeFluidShadowCaster resources.

在文件 VolumeFluidShadowCaster.cpp 第 19 行定义.

引用了 eve::graphics::Graphics::releaseMesh() , 以及 eve::graphics::RenderSystem3D::removeShadowExtraDrawer().

◆ VolumeFluidShadowCaster() [2/2]

eve::fluids::VolumeFluidShadowCaster::VolumeFluidShadowCaster ( const VolumeFluidShadowCaster & )

delete

成员函数说明

◆ operator=()

VolumeFluidShadowCaster & eve::fluids::VolumeFluidShadowCaster::operator= ( const VolumeFluidShadowCaster & )

delete

◆ particleCount()

unsigned eve::fluids::VolumeFluidShadowCaster::particleCount ( ) const

inlinenoexcept

Number of particles in the currently published shadow batch.

在文件 VolumeFluidShadowCaster.h 第 44 行定义.

◆ update()

Result< void > eve::fluids::VolumeFluidShadowCaster::update	(	const VolumeFluid &	fluid,
		unsigned	actorGroup,
		float	radiusScale,
		float	alpha = `1.f`,
		unsigned	maxParticles = `4096`
	)

Rebuild one actor's bounded octahedral shadow batch.

参数

fluid	Borrowed solver, not mutated or retained.
actorGroup	Stable emitter actor identity.
radiusScale	Positive particle radius multiplier.
alpha	Fixed-step interpolation fraction in [0,1].
maxParticles	Complete-output budget in [1,65536].

返回: Success, or failure preserving the prior visible batch.

Reuses CPU arrays and one dynamic GPU mesh after capacity warm-up. The registered CSM callback issues at most one indexed draw per cascade.
