Public Member Functions
int32_t	indexOf (std::string_view name) const
	The index of the bone called name, or -1 when the rig has none.
Public Member Functions inherited from Vkm::Engine::Resource
	Resource (const Resource &other)
	Duplicate other's contents and name, but not its identity.
const std::string &	name () const noexcept
	Serializable identity; non-empty and unique within its type once added.
uint64_t	uid () const noexcept
	Process-unique id stamped by add(); names the asset, not the slot it sits in.
uint64_t	version () const noexcept
	Change counter the backend keys GPU re-uploads on; moved by commit().
bool	isHidden () const noexcept
	Added by ResourceManager::addPrivate: not user-facing, not saved.
nlohmann::json &	sourceJson ()
	Mutable source JSON, allocating a null document if there is none.
const nlohmann::json &	sourceJson () const
	Const source JSON; asserts hasSource(), so guard the call with it.

Public Attributes
std::vector< glm::mat4 >	inverseBind
	Rig model space -> this bone's space, at bind.
std::vector< Transform >	bindPose
	Each bone's local TRS at bind, used wherever a clip has no channel for it.

Detailed Description

A rig: a flat, parent-before-child bone array plus its bind pose.

Bones are indices, not entities. parent < index is validated by findSkeletonFault, so a pose composes in one forward loop and a cycle is unrepresentable. The three vectors are parallel.

Member Function Documentation

indexOf()

int32_t Vkm::Engine::SkeletonAsset::indexOf

(

std::string_view

name

)

const

The index of the bone called name, or -1 when the rig has none.

Linear; resolve once and keep the index rather than calling it per frame.

Parameters

name	Bone name to look for.

Returns

Index into bones, or -1.

Member Data Documentation

bindPose

std::vector<Transform> Vkm::Engine::SkeletonAsset::bindPose

Each bone's local TRS at bind, used wherever a clip has no channel for it.

Stored: deriving it from inverseBind is lossy once a bone carries scale.
