Randomly and Continuously Change Avatar's Face Texture
I would like to make a Sequence that Waits 2-6sec., Randomly changes the texture on the avatar's face, and Repeats.
Based on the post http://www.worldviz.com/forum/showthread.php?t=776 the texture needs to be set to repeating mode. Otherwise, the face is blacked out. See attached files and code. Thanks, Karla Code:

Here is some sample code that uses the vizact library to create an action that does what you want.
Code:
import viz viz.go() #Create quad for displaying texture quad = viz.addTexQuad(pos=(0,1.8,2)) #List of texture filenames files = ['ball.jpg','gb_noise.jpg','brick.jpg','lake3.jpg'] #List of texture objects textures = [ viz.addTexture(f) for f in files ] #Create action that randomly waits between 2-6 seconds waitTime = vizact.waittime( vizact.randfloat(2.0,6.0) ) #Create action that randomly applies texture from list above randomTexture = vizact.texture_node( vizact.choice(textures,vizact.RANDOM) ) #Create sequence that repeats above actions indefinitely my_action = vizact.sequence( waitTime, randomTexture, viz.FOREVER ) #Add action to quad quad.addAction(my_action) |

Avatar's face blacked out
Thanks for the suggestion. It works for quad objects but not for the avatar's face.
The avatar's face becomes blacked out when the texture is applied. There seems to be a difference between applying a texture to an avatar's face and applying it to other objects. I am having a similar problem as in post http://www.worldviz.com/forum/showthread.php?t=776 Using 'texture.wrap(viz.WRAP_S,viz.REPEAT), texture.wrap(viz.WRAP_T,viz.REPEAT),' applies the texture correctly to the avatar's face. Therefore, it is not blacked out when using 'wrap.' How can I incorporate 'wrap' with the random texture application? An error message said "'ActionData' object has no attribute 'wrap'." Thanks, Karla [/CODE] Code:
#August 22nd, 2008 import viz viz.go() #Orient view to look at avatar mv_x = 0; mv_y = 1.78; mv_z = -1.0; viz.MainView.setPosition(mv_x,mv_y,mv_z) mv_euler_x = 180; mv_euler_y = 0; mv_euler_z = 0; viz.MainView.setEuler(mv_euler_x,mv_euler_y,mv_euler_z) #Create avatar for displaying texture character1 = viz.add('male.cfg'); character1.translate(0,0,-1.4572); character1.rotate(0,1,0,0); character1.state(1) #Neutral state of avatar face1 = character1.face('M-0327.vzf') #add a face to the avatar eyes_center = viz.add('M-0327_eyes_Center.jpg'); face1.texture(eyes_center); eyes_center.wrap(viz.WRAP_S,viz.REPEAT); eyes_center.wrap(viz.WRAP_T,viz.REPEAT) #TRYING TO DEFINE A SEQUENCE THAT RANDOMLY CHANGES THE TEXTURE ON THE AVATAR'S FACE #Intention: Make a Sequence that Waits 2-6sec., Randomly changes gaze, Repeats #Use 4 positions (Left, Right, Center, and Up) to create different Eye Contact #List of texture filenames files = ['M-0327_eyes_Left.jpg','M-0327_eyes_Right.jpg','M-0327_eyes_Center.jpg','M-0327_eyes_Up.jpg'] #List of texture objects textures = [ viz.addTexture(f) for f in files ] #Create action that randomly waits between 2-6 seconds waitTime = vizact.waittime( vizact.randfloat(2.0,6.0) ) #Create action that randomly applies texture from list above randomTexture = vizact.texture_node( vizact.choice(textures,vizact.RANDOM) ) #Create sequence that repeats above actions indefinitely my_action = vizact.sequence( waitTime, randomTexture, viz.FOREVER ) #Add action to avatar face1.addAction(my_action) #ERROR: Avatar's face is Blacked-out; need to set texture to repeating mode #Try setting texture to repeating mode #files = ['M-0327_eyes_Left.jpg','M-0327_eyes_Right.jpg','M-0327_eyes_Center.jpg','M-0327_eyes_Up.jpg'] #textures = [ viz.addTexture(f) for f in files ] #waitTime = vizact.waittime( vizact.randfloat(2.0,6.0) ) #randomTexture = vizact.texture_node( vizact.choice(textures,vizact.RANDOM) ) #my_action = vizact.sequence( waitTime, randomTexture, randomTexture.wrap(viz.WRAP_S,viz.REPEAT), randomTexture.wrap(viz.WRAP_T,viz.REPEAT), viz.FOREVER ) #face1.addAction(my_action) #ERROR: Message says 'ActionData' object has no attribute 'wrap' |

Then set the the textures to repeat mode when you add them:
Code:
textures = [ viz.addTexture(f,wrap=viz.REPEAT) for f in files ] |

THANK YOU! THANK YOU! That code solves what I want.
