Tutorial Example - inverted video

Hi

I am following through the example "Getting Your Feet Wet"
and notice that on the screen the video I have selected
is inverted and appears to be a mirror image of what it should be.

#Play a movie on the screen
def playMovie():

mymovie = viz.add('rockpool2.wmv')
mymovie.loop(viz.ON)
mymovie.play()

screen.texture(mymovie)

vizact.onkeydown('m', playMovie)

[question] Can this be adjusted to play correctly.

Thanks

It looks like the texture coordinates on the model are inverted. You can reverse them by using the node.texmat command and setting the wrap mode of the texture to REPEAT:

Code:

#Play a movie on the screen

def playMovie():



        mymovie = viz.add('rockpool2.wmv',wrap=viz.REPEAT)

        mymovie.loop(viz.ON)

        mymovie.play()



        screen.texture(mymovie) 

        screen.texmat(viz.Matrix.scale(-1,1,1))

        

vizact.onkeydown('m', playMovie)

Inverted video

This solution appears to play the video, however the sound only is heard, the picture is a black screen?:confused:

Inverted video

Hi

I was able to invert the video in windows movie maker (using effects) and the video was then inverted in vizard thus playing correctly. However getting a scripting solution would be good so any advice would be great.
