Here is a sample script that adds a mirror to the gallery environment and adds a self avatar that can be seen in the mirror:

import viz
viz.go()

def addMirror(mirror,mat=None):

	#If mirror matrix is not specifed, get matrix of mirror object
	if mat is None:
		mat = mirror.getMatrix()
		
	#Position of mirror
	pos = viz.Vector(mat.getPosition())
	
	#Direction mirror is pointing
	dir = viz.Vector(mat.getForward())
	dir.normalize()

	#Quaternion rotation of mirror
	quat = mat.getQuat()
	
	#Create render texture
	tex = viz.addRenderTexture()
	
	#Create render node for rendering reflection
	lens = viz.addRenderNode(size=[1024,1024])
	lens.attachTexture(tex)
	lens.setInheritView(True,viz.POST_MULT)
	lens.disable(viz.CULL_FACE,op=viz.OP_SET_OVERRIDE)
	
	#Setup reflection matrix
	rot = viz.Matrix.quat(quat)
	invRot = rot.inverse()
	lens.setMatrix(viz.Matrix.translate(pos*-1.0)*invRot*viz.Matrix.scale(1,1,-1)*rot*viz.Matrix.translate(pos))
	
	#Setup reflection clip plane
	plane = vizmat.Plane(pos=pos,normal=dir)
	dist = plane.distance([0,0,0])
	lens.clipPlane([-dir[0],-dir[1],-dir[2],dist+0.001])
	
	#Project reflection texture onto mirror
	mirror.texture(tex)
	mirror.texGen(viz.TEXGEN_PROJECT_EYE)
	
#Add gallery environment
gallery = viz.add('gallery.ive')

#Use existing painting as mirror and specify the matrix
mirror = gallery.getChild('art04-FACES')
m = viz.Matrix()
m.setPosition(mirror.getPosition(viz.ABS_GLOBAL))
m.setEuler(180,0,0)

#Apply mirror settings to mirror object
addMirror(mirror,m)

#Increase ambient lighting
viz.MainView.getHeadLight().ambient(1,1,1)

#Create a self avatar
avatar = viz.add('vcc_female.cfg')

#Link avatar body to viewpoint
avatarLink = viz.link(viz.MainView,avatar)
avatarLink.setPos([None,0,None]) #Keep avatar on floor
avatarLink.setEuler([None,0,0]) #Only update avatar yaw
