3d-movement
I use "vizcave" and I would like to navigate the vitual viewpoint via keyboard. For the real-position of the user I use a tracking-system and for navigation I would like to use the keyboard.
Code:
#Virtual viewpoint (Translate view origin 1 meter up and back) vp = [0, 1, -1] #Use tracker for automatically updating cave cave.setTracker(pos=tracker) #Create vizcave.CaveView object for manipulating viewpoint in cave environment origin = vizcave.CaveView(tracker) #Translate view origin origin.setPosition(vp) Code:
def onKeyDown(key): if key == 'z': #forward vp[2] += 5*viz.elapsed() if key == 'b': #backwards vp[2] -= 5*viz.elapsed() if key == 'g': #left vp[0] -= 5*viz.elapsed() if key == 'h': #right vp[0] += 5*viz.elapsed() origin.setPosition(vp) - First, the movement is not very smooth and - If I rotate the viewpoint (origin.setEuler()) the direction of the movement is the same as before (if I rotate -90 degrees yaw, I have to press "go left" to move forward). How can I smoothen the movement? Is there a function to automatically adapt the movement to the current pos? |
