addText problems with 3 windows
Hi
I have some problems with sowing text via viz.addTest() in a Setup with three windows. The text isn't displayed. creating the Windows: Code:
# Create a new window on the left side self.LeftWindow = viz.add(viz.WINDOW) self.LeftWindow.position(0, 1) self.LeftWindow.size(1.0/3, 1.0) self.LeftWindow.visible(0,viz.SCREEN) self.LeftWindow.fov(FOV,ASPECT_RATIO) #print self.LeftWindow #self.CenterWindow = viz.add(viz.WINDOW) #self.CenterWindow.position(1.0/3, 1.0) #self.CenterWindow.size(1.0/3, 1.0) #self.CenterWindow.visible(0,viz.SCREEN) #self.CenterWindow.fov(FOV,ASPECT_RATIO) self.CenterWindow = viz.MainWindow self.CenterWindow.position(1.0/3, 1.0) self.CenterWindow.size(1.0/3, 1.0) self.CenterWindow.visible(0,viz.SCREEN) self.CenterWindow.fov(FOV,ASPECT_RATIO) #Create a new window on the right side self.RightWindow = viz.add(viz.WINDOW) self.RightWindow.position(2.0/3, 1.0) self.RightWindow.size(1.0/3, 1.0) self.RightWindow.visible(0,viz.SCREEN) self.RightWindow.fov(FOV,ASPECT_RATIO) # Create new viewports self.LeftView = viz.add(viz.VIEWPOINT) self.RightView = viz.add(viz.VIEWPOINT) self.CenterView = viz.add(viz.VIEWPOINT) #Attach the the viewports to the windows self.LeftWindow.viewpoint(self.LeftView) self.RightWindow.viewpoint(self.RightView) self.CenterWindow.viewpoint(self.CenterView) #Rotate the view so that it looks down #set the viewing angle for the windows self.LeftView.rotate(1,LEFT_ANGLE,0,0) self.RightView.rotate(1,RIGHT_ANGLE,0,0) Code:
self.anweisung = viz.addText("",viz.SCREEN,self.CenterWindow) self.anweisung.translate(0.5,0.5) self.anweisung.color(viz.RED) Unfortunately there is no text displayed, since we changed to the 3 window setup. With one it is working poperly. Any idea why this isn't working? |

If you specify a window object as the scene of a text, then you need to specify viz.ORTHO as the parent, not viz.SCREEN. Also, when adding object to the viz.ORTHO layer, the position units are in pixels, not normalized coordinates. Here is sample code:
Code:
self.anweisung = viz.addText("hello",viz.ORTHO,self.CenterWindow,fontSize=32) self.anweisung.translate(50,50) #50 pixel from bottom left corner of window |
