BoneBindPose

Description

A table structure representing a single bone's orientation when its mesh is in its baseline (or "bind") pose before any animation is played.

This structure does not contain the bone ID for the bone it represents and instead relies on the structure's index within the table returned by util.GetModelMeshes to identify the bone it corresponds to.

Example: Gets every bone's bind pose in model space, and relative to its parent bone (the form an animation sets a bone in).

local _, bindPoses = util.GetModelMeshes( "models/player/kleiner.mdl" ) for boneId = 0, #bindPoses do local bindPose = bindPoses[ boneId ] -- The bone's position and rotation in model space local boneToModel = bindPose.matrix:GetInverseTR() -- The same relative to its parent: the parent's matrix already goes from model space into the parent's space local parentBindPose = bindPoses[ bindPose.parent ] local boneToParent = parentBindPose and parentBindPose.matrix * boneToModel or boneToModel print( boneId, boneToModel:GetTranslation(), boneToParent:GetTranslation() ) end

Members

number parent
The bone ID of this bone's parent bone.
VMatrix matrix
The inverse of this bone's bind pose transform: it converts a position from model space into this bone's local space (Source's poseToBone). Use matrix:GetInverseTR() to get the bone's position and rotation in model space.
