Loading Object Time

Hi All,

I am running an experiment currently that involves loading a number of photographic stimuli into Vizard. I have created a city scene myself by scaling different photographs and also created multiple vehicles within the scene through scaling different photographs.

My question is - the first trial always takes a little longer to load and seems to only be a very brief presentation.

Is there a way to load the city in that will not take up so much memory? Below is how I set up the city (I'm sure there is a more efficient coding method).

Best wishes

Code:
#Create sky
sky = viz.add('skydome.dlc')
sky.texture(viz.add(viz.ENVIRONMENT_MAP,'sky.jpg'))

# ----------------------------------------------#
#           SET UP GRID LINES         #
# ----------------------------------------------#
grid = vizshape.addGrid([2,1],step=0.2,boldStep=None,axis=vizshape.AXIS_Z,parent=viz.SCREEN)
grid.color(viz.RED)
grid.setPosition([0,0.5,0])
grid.visible(viz.OFF)

# ----------------------------------------------#
#           SET UP RESPONSE Zones         #
# ----------------------------------------------#
