Pygame Screen within Vizard World

Hello everyone,

at the risk of asking a silly question I would like ask wether anyone knows how one could have a screen with a pygame game on within Vizard.

The same way Vizard offers the possibility to play a video file on a virtual object (e.g. 3d model of a screen) with the viz.addVideo() function, would it be possible to blit (hope that's the correct term...) a pygame animation on a screen model within a model of a virtual room? Or would there be some other way with Python using some of pygame's functions?

Best regards and many thanks!

Alvin

To be clear, you want to display the live output of a pygame application as a texture in Vizard?

Hello,

thank you for your quick answer! Yes exactly! Essentially what we would like to do is to run a little experiment programmed with pygame on a 3d model of a screen in a virtual model of a room. So it would be sort of a "virtual recreation" of a normal psychological experimental setting. Would you know an existing solution to do this?

Best regards and many thanks!

I needed something similar, and my solution was to have one laptop running the program I wanted to show in Vizard. On another computer, I use a webcam to film the contents of that laptop, and show the videofeed of that webcam on a texture in Vizard. See the example code below. Something similar may be a solution for you as well.

Code:

viz.go()

screen = viz.addTexQuad(size=4)

#Create Video Camera extension

video = viz.add('VideoCamera.dle')

#Connect to next available generic video capture device

cam = video.addWebcam()

#Apply videofeed of webcam as a texture of the screen

screen.texture(cam)

See (this thread: http://forum.worldviz.com/showthread.php?t=4458) for another suggestion of using VLC to capture the desktop of a computer running the pygame and stream it out via directshow.

Hello Mr Verberne,

thank you very much for your solution, this is an ingenious idea! I will definitely try to do that.

Many thanks and best regards!
