Viewpoint Compass
Hi,
I am creating an application that has a pretty large CAD model and when the users are navigating through the model there have been complaints that they are losing track of where they are in the model. I want to create a "you-are-here" type window that the user can pop up on the screen. I have been experimenting with addWindow() and addView() to get a top down view of the environment. I would like to be able to insert an arrow over this window that follows the position and orientation of the main viewpoint. Is this possible? Thanks! -- Patrick |

Here is a sample script that shows how to overlay objects on a sub-window:
Code:
import viz import vizact viz.go() #Add the room and arrow room = viz.add('gallery.ive') # Create a new window in the upper left corner UpperLeftWindow = viz.addWindow(pos=(0,1.0),size=(0.2,0.2)) UpperLeftWindow.visible(0,viz.SCREEN) # Create a new viewpoint BirdView = viz.addView() #Attach the bird's eye view to the upper left window UpperLeftWindow.setView(BirdView) #Move the view above the center of the room BirdView.setPosition([0,9,0]) #Rotate the view so that it looks down BirdView.setEuler([0,90,0]) #Overlay arrow on sub window (20x20 pixels) arrow = viz.addTexQuad(parent=viz.ORTHO,scene=UpperLeftWindow,size=20) arrow.texture(viz.add('arrow.tif')) def UpdateArrow(): #Get the current head orientation and position yaw,pitch,roll = viz.MainView.getEuler() pos = viz.MainView.getPosition() # Place arrow on top of viewpoint x,y,z = UpperLeftWindow.worldToScreen(pos,mode=viz.WINDOW_PIXELS) arrow.setPosition([x,y,0]) # Rotate arrow to match yaw rotation arrow.setEuler([0,0,-yaw]) vizact.ontimer(0,UpdateArrow) |
