How to show different objects on different windows from the same scene

Hello,

I have two windows. On on each window I want to show different objects on the viz.SCREEN, but the rest of the scene must be the same. What is the best way to do that?

Greetings, Joran.

There are two ways to go about this.

1) Each window has its own orthographic HUD. The window HUD is slightly different than the SCREEN because the coordinates are in actual pixel units, not normalized 0 to 1. Here is a sample script that adds a different text object to each windows HUD:

Code:

import viz

viz.go()



#Set main window size to half

viz.MainWindow.setSize(0.5,1)



#Add a new window to other half

window = viz.addWindow()

window.setPosition(0.5,1)

window.setSize(0.5,1)



#Add a model

viz.add('gallery.ive')



#Add text to the main windows orthographic HUD

text1 = viz.add(viz.TEXT3D,'Text 1',parent=viz.ORTHO,scene=viz.MainWindow)

text1.fontSize(36)



#Add text to the second windows orthographic HUD

text2 = viz.add(viz.TEXT3D,'Text 2',parent=viz.ORTHO,scene=window)

text2.fontSize(36)

2) Use 2 different scenes that share the same data. Example:

Code:

import viz

viz.go()



#Set main window size to half

viz.MainWindow.setSize(0.5,1)



#Add a new window to other half

window = viz.addWindow()

window.setPosition(0.5,1)

window.setSize(0.5,1)

view = viz.addView()

view.scene(2)

window.viewpoint(view)



#Add the root of your entire scene

root = viz.add(viz.GROUP)



#Duplicate this root onto scene 2

root.duplicate(scene=2)



#Add all subsequent world objects to this root

gallery = root.add('gallery.ive')



#Add text to scene 1 screen

text1 = viz.add(viz.TEXT3D,'Text 1',parent=viz.SCREEN,scene=1)



#Add text to scene 2 screen

text2 = viz.add(viz.TEXT3D,'Text 2',parent=viz.SCREEN,scene=2)

Hi farshizzo,

I was able to copy your code to produce two different scenes that share the data, but cannot not use viz.add for anything other than text. For example, if I try:

#Add ball to scene 2 screen
ball = viz.add('white_ball.wrl',parent=viz.SCREEN,scene=2 )

the ball does not appear in the window. How can I add different types of nodes?

Try scaling the ball by a large value such as 1000. You can also add it to the ortho layer:

Code:

ball = viz.add('white_ball.wrl',parent=viz.ORTHO, scene=2)

ball.setPosition([300,300,1])

ball.setScale([100]*3)
