Perception Neuron Mocap Skeleton
Method #
This node reads bone data from a Perception Neuron motion capture suit and applies it to Bone nodes, either via direct input links or by a connection to the root of the target hierarchy. A network connection must be made to the Axis Neuron software which provides a stream of bone data from the suit. The server address and port must be entered to match the output address and port in Axis Neuron. If there is no connection the node will be hatched out in red.
The input skeleton the node is applied to must have been designed to receive motion capture data: the bones must be named, oriented and arranged appropriately. Mixamo rigs are a good reference.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Axis Neuron Server Address The address / IP of the Axis Neuron server providing the skeleton stream.
Axis Neuron Server Port The port of the Axis Neuron server providing the skeleton stream.
Avatar Index Select the mocap actor to drive the skeleton.
Input Skeleton Scale Uniformly scale the size of the input mocap skeleton.
Mirrored Mirror the movements of the incoming mobcap data along the x axis.
Flip Z Flip the Z axis of the skeleton, to match a model with a flipped z axis.
