Method Summary

private static void	alignSegment(VJoint skeletonRoot, String parentSid, String childSid, float[] vec)
static Map<String,String>	getRenaming(String renamingList, List<GNode> rootNodes) Renames the sids from skeleton joint, both in skeletons and in skinned meshes.
private static void	prepareBindPose(VJoint joint, float[] parentRotation) assuming that we have reached the current pose from a bind pose where all rotation was Id, we want to prepare a pose that can be used to set the new bind pose.
static void	setHAnimPose(VJoint skeletonRoot) Tries to set the skeleton in the HAnim neutral pose.

Method Detail

getRenaming

public static Map<String,String> getRenaming(String renamingList,
                                             List<GNode> rootNodes)

Renames the sids from skeleton joint, both in skeletons and in skinned meshes. The new sid will be used both as joint sid and joint name (but not as joint id)

alignSegment

private static void alignSegment(VJoint skeletonRoot,
                                 String parentSid,
                                 String childSid,
                                 float[] vec)

setHAnimPose

public static void setHAnimPose(VJoint skeletonRoot)

Tries to set the skeleton in the HAnim neutral pose. It is assumed that joints have joint sids according to the HAnim standard. Assumes the ankles are aligned correctly for 'stable' standing, re-aligns them so that the ankle stance is maintained.

prepareBindPose

private static void prepareBindPose(VJoint joint,
                                    float[] parentRotation)

assuming that we have reached the current pose from a bind pose where all rotation was Id, we want to prepare a pose that can be used to set the new bind pose.

setNeutralPoses

public static void setNeutralPoses(List<GNode> skeletonRoots,
                                   List<GSkinnedMesh> skinnedMeshList,
                                   List<GNode> roots)
