Using current scene as a texture?

[iva]

I don't know how to exactly explain what am I trying to do. I want to have a screen somewhere in the Vizard scene that is showing the scene from a certain viewpoint. I know how to do it in different windows, but windows are parented to screen, and I would like, somehow, to have them parented to the world, which doesn't really work. Does anybody have any ideas?

Okay, I cannot edit my message, but I solved the problem and here is my code:


import viz

viz.go()
view=viz.MainView
viz.MainView.setPosition(-1.5,2.5,-6)
viz.MainView.setEuler(0,10,0)
viz.fov(70)

scene=viz.add("piazza.osgb")



WALL_SCALE = [1.6, 1.87, 1]

wall = viz.addTexQuad(size=1.87)
wall.setPosition( [-2, 0, 0] )
wall.zoffset(1) #avoid zfighing, make wall appear behind pictures
wall.setScale( WALL_SCALE )


wallL = viz.addTexQuad(size=1.87)
wallL.setPosition( [-3.5, 0, -1.5] )
wallL.setEuler(-90,0,0)
wallL.zoffset(1) #avoid zfighing, make wall appear behind pictures
wallL.setScale( WALL_SCALE )

wallR = viz.addTexQuad(size=1.87)
wallR.setPosition( [-0.5, 0, -1.5] )
wallR.setEuler(90,0,0)
wallR.zoffset(1) #avoid zfighing, make wall appear behind pictures
wallR.setScale( WALL_SCALE )




male = viz.add('vcc_male.cfg')
male.setPosition([-2, 0,-1.5])
male.state(9)

logo = viz.add('logo.ive',pos=(0,3,6))
logo.addAction(vizact.spin(0,1,0,45))
logo.scale(0.5, 0.5, 0.5)
# Create render texture
tex = viz.addRenderTexture()
texL = viz.addRenderTexture()
texR = viz.addRenderTexture()

# middle cave wall
cam = viz.addRenderNode()
cam.setSize(512,512)
cam.setInheritView(False)
cam.setPosition([0.0, 2.0, 0])
cam.lookAt([0,2,33])
cam.setFov(60,1.0,0.1,100)
cam.setRenderTexture(tex)
cam.setRenderLimit(viz.RENDER_LIMIT_FRAME)
wall.texture(tex)

# left cave wall
camL = viz.addRenderNode()
camL.setSize(512,512)
camL.setInheritView(False)
camL.setPosition([0, 2.0, 0])
#camL.setEuler([-90,0,0])
camL.lookAt([-19,2,11])
camL.setFov(60,1.0,0.1,100)
camL.setRenderTexture(texL)
camL.setRenderLimit(viz.RENDER_LIMIT_FRAME)
wallL.texture(texL)

# right cave wall
camR = viz.addRenderNode()
camR.setSize(512,512)
camR.setInheritView(False)
camR.setPosition([0.0, 2, 0])
camR.lookAt([19,2,11])
camR.setFov(60,1.0,0.1,100)
camR.setRenderTexture(texR)
camR.setRenderLimit(viz.RENDER_LIMIT_FRAME)
wallR.texture(texR)


I was trying to have a mini-cave inside of my scene, this is good enough :)

For future reference you can always look at the 'The Pit' world demo, as well as the mirror script that's in the Worldviz Knowledge Base ;)

There are also some examples of using render nodes to render the scene to a texture in the Vizard/examples/renderNodes folder.

Hm, I completely forgot that the pit has this camera-like thingy. Oh well:)
