Making a HD Complete Character blink

[Frank Verberne]

Hi Jeff,

Sounds like a good idea! However, I've tried to print the eulers (also tried quaternions) of the eye related bones, while running one of the standard animations and was unable to detect changes in eulers (or quaternions) of those bones. So I don't know how the HD character blinks during the standard animations. In its cfg file, no blink morph is specified, so blinking is not accomplished through applying a moprh. Any suggestions?

import viz
import vizact

viz.go()

avatar = viz.add('vcc_male2.cfg', pos = [0,.15,.25], euler = [180,0,0])
avatar.state(1)
boneList = []

for bone in avatar.getBoneList():
	if 'Eye' in bone.getName() and not (('brow' in bone.getName()) or 'Nub' in bone.getName()):
		boneList.append(bone)

def printInfo():
	for bone in boneList:
		print bone.getName(), bone.getEuler()
	
vizact.ontimer(viz.FASTEST_EXPIRATION, printInfo)

Okay, I'm pretty sure the eyelids are not moved by bones. I've tried recording a little piece of one of the standard animations of the sample HD character, with blinking included. Uncomment vizact.onexit(saveTrackingData) to enable saving. Warning: the resulting file gets big (for a .log file) fast:

import viz
import vizact
import cPickle

viz.go()

avatar = viz.add('vcc_male2.cfg', pos = [0,.15,.25], euler = [180,0,0])
avatar.state(1)
boneList = []
boneNameList = []

for bone in avatar.getBoneList():
	boneList.append(bone)
	boneNameList.append(bone.getName())

global bone_info, total_info
bone_info = []
total_info = []

def updateBoneInfo():
	global bone_info, total_info
	for bone in boneList:
		bone_info.append(bone.getName())
		bone_info.append(bone.getEuler())
	total_info.append(bone_info)
	bone_info = []

vizact.ontimer(viz.FASTEST_EXPIRATION, updateBoneInfo)

BONE_DATA = open("Recording_of_bones.log", 'w+') 

def saveTrackingData(): 
	global total_info
	cPickle.dump(total_info, BONE_DATA) 
	BONE_DATA.flush() 
	BONE_DATA.close() 

#vizact.onexit(saveTrackingData)

Then, I played back the recordings on the same avatar, and the whole animation is played back, EXCEPT for the blinking (press the b-key for playback if the previous code is used to create a short recording):

import viz
import vizact
import viztask
import cPickle
from collections import deque 

viz.go()

avatar = viz.add('vcc_male2.cfg', pos = [0,.15,.25], euler = [180,0,0])
boneList = []
boneNameList = []

for bone in avatar.getBoneList():
	boneList.append(bone)
	boneNameList.append(bone.getName())

for bone in boneList:
	bone.lock()
	
BONE_DATA = open("Recording_of_bones.log", 'r') 

def setBones():
	total_info = deque(cPickle.load(BONE_DATA)) 
	yield viztask.waitDraw()
	while len(total_info) > 0:
		line = line = deque(total_info.popleft())
		while len(line) > 0:
			boneName = line.popleft()
			boneOrientation = line.popleft()
			if boneName in boneNameList:
				index = boneNameList.index(boneName)
				boneList[index].setEuler(boneOrientation)
			else:
				print 'bone not found on character!'
		yield viztask.waitDraw()

def onKeyDown(key):
	if key in 'bB':
		viztask.schedule(setBones)

viz.callback(viz.KEYDOWN_EVENT,onKeyDown)

So that would rule out any bone involvement in blinking of the eyes. Any other suggestions?
