+## Section 2: Cubism params calculation control
+#
+# These values control how the facial landmarks are translated into
+# parameters that control the Cubism model, and will vary from person
+# to person. The following values seem to work OK for my face, but
+# your milage may vary.
+
+# Section 2.1: Face Y direction angle (head pointing up/down)
+# The Y angle is calculated mainly based on the angle formed
+# by the corners and the tip of the nose (hereafter referred
+# to as the "nose angle").
+
+# This applies an offset (in degrees).
+# If you have a webcam at the top of your monitor, then it is likely
+# that when you look at the centre of your monitor, the captured image
+# will have you looking downwards. This offset shifts the angle upwards,
+# so that the resulting avatar will still be looking straight ahead.
+faceYAngleCorrection 10
+
+# This is the baseline value for the nose angle (in radians) when looking
+# straight ahead...
+faceYAngleZeroValue 1.8
+
+# ... and this is when you are looking up...
+faceYAngleUpThreshold 1.3
+
+# ... and when looking down.
+faceYAngleDownThreshold 2.3
+
+# This is an additional multiplication factor applied per degree of rotation
+# in the X direction (left/right) - since the nose angle reduces when
+# turning your head left/right.
+faceYAngleXRotCorrection 0.15
+
+# This is the multiplication factor to reduce by when smiling or laughing -
+# the nose angle increases in such cases.
+faceYAngleSmileCorrection 0.075
+
+
+# Section 2.2: Eye control
+# This is mainly calculated based on the eye aspect ratio (eye height
+# divided by eye width). Note that currently an average of the values
+# of both eyes is applied - mainly due to two reasons: (1) the dlib
+# dataset I'm using fails to detect winks for me, and (2) if this is
+# not done, I frequently get asynchronous blinks which just looks ugly.
+
+# Maximum eye aspect ratio when the eye is closed
+eyeClosedThreshold 0.2
+
+# Minimum eye aspect ratio when the eye is open
+eyeOpenThreshold 0.25
+
+# Max eye aspect ratio to switch to a closed "smiley eye"
+eyeSmileEyeOpenThreshold 0.6
+
+# Min "mouth form" value to switch to a closed "smiley eye"
+# "Mouth form" is 1 when fully smiling / laughing, and 0 when normal
+eyeSmileMouthFormThreshold 0.75
+
+# Min "mouth open" value to switch to a closed "smiley eye"
+# "Mouth open" is 1 when fully open, and 0 when closed
+eyeSmileMouthOpenThreshold 0.5
+
+
+# Section 2.3: Mouth control
+# Two parameters are passed to Cubism to control the mouth:
+# - mouth form: Controls smiles / laughs
+# - mouth openness: How widely open the mouth is
+# Mouth form is calculated by the ratio between the mouth width
+# and the eye separation (distance between the two eyes).
+# Mouth openness is calculated by the ratio between the lip separation
+# (distance between upper and lower lips) and the mouth width.
+
+# Max mouth-width-to-eye-separation ratio to have a normal resting mouth
+mouthNormalThreshold 0.75
+
+# Min mouth-width-to-eye-separation ratio to have a fully smiling
+# or laughing mouth
+mouthSmileThreshold 1.0
+
+# Max lip-separation-to-mouth-width ratio to have a closed mouth
+mouthClosedThreshold 0.1
+
+# Min lip-separation-to-mouth-width ratio to have a fully opened mouth
+mouthOpenThreshold 0.4
+
+# Additional multiplication factor applied to the mouth openness parameter
+# when the mouth is fully smiling / laughing, since doing so increases
+# the mouth width
+mouthOpenLaughCorrection 0.2
+
+
+## Section 3: Filtering parameters
+# The facial landmark coordinates can be quite noisy, so I've applied
+# a simple moving average filter to reduce noise. More taps would mean
+# more samples to average over, hence smoother movements with less noise,
+# but it will also cause more lag between your movement and the movement
+# of the avatar, and quick movements (e.g. blinks) may be completely missed.
