Modeling changing facial expressions?
Hi all
I need my avatar to express several emotions that should be changing fluently. For example I want the avatar to smile and then change to frown. How can I do this? I guess using some sort of morphing? I know that I can attach a head to my avatar, so I could create 2 heads (one smiling and one frowning) and then morph from one to the other, right? Could anyone please give me a hint into the right direction for doing this? :-) Best would be if I could morph also to a certain degree, let's say 50%, so the facial expression would be neutral then. Is this possible? Thanks a lot :-) Josh |

Hey,
great question, unfortunately I as well don't know how to implement this, but i did make my avatar yawn so if it could be of any use to you : def makeAvatarYawn(avatar,eyes,eyebrows,mouth,isOpenin g) : increaseFactor = 0.1 waitTimeFactor = 0.07 maxOpenTime = 0.4 maxOpen = 3 if isOpening : eyes = eyes + increaseFactor*0.5 eyebrows = eyebrows + increaseFactor mouth = mouth + increaseFactor if mouth >= maxOpen : isOpening = False yield viztask.waitTime(maxOpenTime) else : eyes = eyes - increaseFactor*0.65*0.5 eyebrows = eyebrows - increaseFactor*0.65 mouth = mouth - increaseFactor*0.65 avatar.morph(0,eyes) avatar.morph(1,eyebrows) avatar.morph(2,mouth) yield viztask.waitTime(waitTimeFactor) if mouth > 0 : viztask.schedule(makeAvatarYawn(avatar,eyes,eyebro ws,mouth,isOpening)) viztask.schedule(makeAvatarYawn(avatar,0,0,0,True) ) |
