Flipped floor in a CAVE

Hello again ,

I am running Vizard on a 4 wall CAVE system at Rowan University.

I have read your CAVE file and have tried to create one of our own
for us to use with a Left, Right, Front and Bottom setup.

However, I consistently run into an issue where the bottom node seems
to be flipped. We are also running a PPT tracking system and an Inertia
Cube 3 wireless sensor.

I have setup the CAVE's center to be the literal center of the CAVE (height, width /2)

Code:
import viz
import vizcave
import viztracker
import math
import VectorHelper

def CaveInit():
#Center is always assumed to be the red box on
#the floor of the CAVE (wallpaper)
#Use the PPT Tracker Offset command to fix
#where the true center is if adjustments are needed...

#Y Height should always be positive

#CAVE Dimensions in Meters
CAVE_W	= 3.048
CAVE_H	= 2.286

#Half Cave Dimensions
CAVE_W2 	= CAVE_W / 2.0	# Half width
CAVE_H2		= CAVE_H / 2.0	# Half height
#CAVE Vertices
# c0   c1   c2   c3
# *----*----*----*
# | L  |  F |  R |
# *----*----*----*
# c4 c5|  B |c6 c7
#      *----*
#      b4  b7
#
C0 = -CAVE_W2,CAVE_H,-CAVE_W2
C1 = -CAVE_W2,CAVE_H,CAVE_W2
C2 = CAVE_W2,CAVE_H,CAVE_W2
C3 = CAVE_W2,CAVE_H,-CAVE_W2
C4 = -CAVE_W2,0,-CAVE_W2
C5 = -CAVE_W2,0,CAVE_W2
C6 = CAVE_W2,0,CAVE_W2
C7 = CAVE_W2,0,-CAVE_W2

#CAVE FLOOR OFFSET DUE TO THE DEPTH NOT EQUALING THE WIDTH
OFFSET = 0.762

B4 = -CAVE_W2, 0, -CAVE_W2 + OFFSET
B7 = CAVE_W2, 0, -CAVE_W2 + OFFSET

# Create front wall
FrontWall = vizcave.Wall(	upperLeft=C1,
upperRight=C2,
lowerLeft=C5,
lowerRight=C6,
name='Front Wall' )

# Create left wall
LeftWall = vizcave.Wall(	upperLeft=C0,
upperRight=C1,
lowerLeft=C4,
lowerRight=C5,
name='Left Wall' )

# Create right wall
RightWall = vizcave.Wall(	upperLeft=C2,
upperRight=C3,
lowerLeft=C6,
lowerRight=C7,
name='Right Wall' )

# Create bottom wall
BottomWall = vizcave.Wall(	upperLeft=C5,
upperRight=C6,
lowerLeft=B4,
lowerRight=B7,
name='Bottom Wall' )

# Create cave object
cave = vizcave.Cave()
#cave.setIPD(0.06)
#cave.setNearPlane(0.15)
cave.setFarPlane(1000.0)
