详细描述

Root-to-skin binding table (UE UGroomBindingAsset analogue, CPU-only).

Built once against a rest mesh; applied each frame (or on demand) against a deformed mesh that shares topology. Does not depend on the animation module — callers supply packed positions.

@thread Affine to the caller; not synchronized. @reentrancy Does not invoke callbacks.

成员函数说明

◆ build()

Result< void > eve::graphics::hair::GroomBinding::build	(	const StrandsDatas &	strands,
		const SkinTriMesh &	restMesh
	)

Project every strand root onto the closest rest-mesh triangle. @ownership Overwrites this binding; strands remain caller-owned.

在文件 Binding.cpp 第 164 行定义.

引用了 a, b, bary, eve::graphics::hair::RootAttach::barycentric, c, eve::Diagnostic::error(), eve::Failed, eve::Result< T >::failure(), found, eve::graphics::hair::SkinTriMesh::indexCount, eve::InvalidArgument, eve::InvariantViolation, ok, eve::graphics::hair::RootAttach::restNormal, eve::graphics::hair::RootAttach::restRoot, root, strands, eve::Result< T >::success() , 以及 eve::graphics::hair::RootAttach::triangleIndex.

◆ clear()

void eve::graphics::hair::GroomBinding::clear ( )

在文件 Binding.cpp 第 217 行定义.

◆ deform()

Result< StrandsDatas > eve::graphics::hair::GroomBinding::deform	(	const StrandsDatas &	restStrands,
		const SkinTriMesh &	deformedMesh,
		BindingDeformMode	mode = `BindingDeformMode::Rigid`
	)		const

Deform rest strands using this binding and a deformed skin mesh.

返回: A new StrandsDatas (same curve topology); rest strands unchanged.

在文件 Binding.cpp 第 224 行定义.

◆ rootAt()

const RootAttach * eve::graphics::hair::GroomBinding::rootAt ( size_t index ) const

Root at.

在文件 Binding.cpp 第 219 行定义.

引用了 index.

◆ rootCount()

size_t eve::graphics::hair::GroomBinding::rootCount ( ) const

inline

Root count.
