I am also having a lot of trouble trying to implement a mirror. In this version I cannot seem to get the mirror to reflect avatars:
import viz
import time
import vizact
viz.go()
clock = 0
PERSON_HEIGHT = 1.5
GRAVITY = 9.81
OFFSET = 0 #Offset due to the room model load
print OFFSET
light = viz.MainView.getHeadLight()
light.disable()
roomGroup = None
viz.clearcolor(0.1,0.1,0.3)
labRoom = viz.add('LabRoom.ive')
labRoom.setPosition(0, OFFSET, 0)
#Correct view height
viz.MainView.eyeheight(0)
##---------------------------------------------------------------------
##Configure tracking
##---------------------------------------------------------------------
##Orientation of the HMD
#isense = viz.add('intersense.dls')
##isense.addTracker() #adding the tracker #Commented out because of the dls file (instead of a dle
#view = viz.MainView #defining the main view
#vrpn = viz.add('vrpn7.dle') #Interface with PPT computer
#PPT_HOSTNAME = '171.64.33.43' #PPT IP address
##Adding the tracker to the orientation
#headMarker = vrpn.addTracker('PPT0@' + PPT_HOSTNAME, 0)
##Linking the orientation to the main view
#headOri = viz.link(isense, view, mask = viz.LINK_ORI, priority = 0)
##Linking the PPT to the mainview
#headPos = viz.link(headMarker, view, mask = viz.LINK_POS, priority = 0)
##Specify HMD model
#nvis.nvisorSX111()
#--------------------------------------------------------
#Mirror
#--------------------------------------------------------
REFLECT_MASK = viz.addNodeMask()
def addMirror(mirror,mat=None,eye=viz.BOTH_EYE):
#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=[512,512])
lens.attachTexture(tex)
lens.setInheritView(True,viz.POST_MULT)
lens.disable(viz.CULL_FACE,op=viz.OP_OVERRIDE)
if eye == viz.LEFT_EYE:
lens.disable(viz.RENDER_RIGHT)
mirror.disable(viz.RENDER_RIGHT)
elif eye == viz.RIGHT_EYE:
lens.disable(viz.RENDER_LEFT)
mirror.disable(viz.RENDER_LEFT)
mirror.renderToAllRenderNodesExcept([lens])
#Setup reflection matrix
rot = viz.Matrix.quat(quat)
invRot = rot.inverse()
lens.setMatrix(viz.Matrix.translate(-pos)*invRot*viz.Matrix.scale(1,1,-1)*rot*viz.Matrix.translate(pos))
#Setup reflection clip plane
s = viz.sign(viz.Vector(dir) * viz.Vector(pos))
plane = vizmat.Plane(pos=pos,normal=dir)
dist = plane.distance([0,0,0])
lens.clipPlane([dir[0],dir[1],dir[2],s*dist-0.01])
#Project reflection texture onto mirror
mirror.texture(tex)
mirror.texGen(viz.TEXGEN_PROJECT_EYE)
viz.startlayer(viz.QUADS)
#Hardcoding the mirror's plane
viz.texcoord(0,0)
viz.vertex( 6.35 , OFFSET + 1.4 , -3.1)
viz.texcoord(0,1)
viz.vertex( 6.35 , OFFSET + 2.85, -3.1)
viz.texcoord(1,1)
viz.vertex( 2.8 , OFFSET + 2.85, -3.1)
viz.texcoord(1,0)
viz.vertex( 2.8 , OFFSET + 1.4 , -3.1)
mirrorRight = viz.endlayer( )
mirrorLeft = mirrorRight.copy()
#specify the matrix
m = viz.Matrix()
m.setPosition([0.25,1,0.25])
m.setEuler(0 , 0 ,0) #This determines which way the mirror is facing
#Apply mirror settings to mirror object
addMirror(mirrorRight,m,viz.RIGHT_EYE)
addMirror(mirrorLeft,m,viz.LEFT_EYE)
#Increase ambient lighting
#viz.MainView.getHeadLight().ambient(1,1,1)
#--------------------------------------------------------
#Create a self avatar
#--------------------------------------------------------
avatar = viz.add('vcc_female.cfg')
avatar.setScale(1.7,1.7,1.7)
#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
avatar.setMask(viz.LEFT_MASK|viz.RIGHT_MASK,mode=v iz.MASK_REMOVE) #Only draw avatar in mirror
#Link avatar head to viewpoint
head = avatar.getBone('Bip01 Head')
head.lock()
viz.link(viz.MainView,head,mask=viz.LINK_ORI)
avatar2 = viz.add('vcc_female.cfg')
avatar2.setPosition(4, .1, 0)
avatar2.setScale(1.7,1.7,1.7)
