aiToGlm()

glm::mat4 anim_utils::aiToGlm

(

const aiMatrix4x4 &

m

)

Convert an Assimp row-major 4x4 matrix to GLM column-major.

Parameters

m	Source assimp matrix.

Returns

Equivalent GLM mat4.

buildJoint()

bool anim_utils::buildJoint	(	const aiNode *	node,
		const std::unordered_set< std::string > &	boneNames,
		ozz::animation::offline::RawSkeleton::Joint &	outJoint,
		std::unordered_map< std::string, JointRestPose > &	restPoses
	)

Recursively build a RawSkeleton joint tree from the Assimp node hierarchy.

Only includes nodes that are bones or ancestors of bones (prunes mesh nodes and other non-skeletal branches).

Parameters

node	Current Assimp node to process.
boneNames	Set of bone names referenced by meshes.
outJoint	Output joint to populate.
restPoses	Map to store rest-pose transforms keyed by joint name.

Returns

True if this node or any descendant is a bone.

ozzToGlm()

glm::mat4 anim_utils::ozzToGlm

(

const ozz::math::Float4x4 &

m

)

Convert an ozz SIMD 4x4 matrix to a GLM column-major mat4.

Parameters

m	Source ozz matrix.

Returns

Equivalent GLM mat4 (column-major).
