 C3D Parameter FORCE_PLATFORM:ORIGIN
-===== AMTI force platforms =====
+==== AMTI force platforms ====
 The ORIGIN is the vector from the sensor coordinate system to the top center of the force platform surface. It is expressed in the force platform coordinate system, so the z-value is defined to be negative.
-===== KISTLER force platforms =====
+==== KISTLER force platforms ====
 The ORIGIN is a vector comprised of the following components.

   - z= distance from the sensor coordinate system to the top surface of the force platform surface. This value should be negative
-===== BERTEC force platforms =====
+==== BERTEC force platforms ====
 Contact the manufacturer because the origin value varies with the type of BERTEC force platform. For recent Force Platforms Bertec has elected to calibrate their force platforms differently from the other manufacturers.
@@ Line 21: / Line 23: @@
 For newer digital platforms, the CalMatrix has been computed assuming an ORIGIN value of (0, 0, 0)
-===== BERTEC treadmills =====
+==== BERTEC treadmills ====
 Bertec uses an ORIGIN of (236,813,0) and (-236,813,0), which is a nuisance for Vicon users because Vicon stores the ORIGIN parameter incorrectly.
@@ Line 33: / Line 35: @@
 Vicon users with Bertec treadmills, should use a very small z-component 0.0001 so that Visual3D knows to multiply by -1.

+==== Guessing the correct FORCE_PLATFORM::ORIGIN ====
 The C3D file format is a public document (http://www.c3d.org) that most hardware vendors currently export. We are only aware of one implementation of the format that has an inconsistency that Visual3D must handle explicitly.
