The OpenVR CHOP receives positional data from the OpenVR SDK. Each CHOP can output in one of 3 modes:
Tracking Sensors, Projection Matrices and Controllers:
Parameters - Setup Page
active - Control if this node is querying data from the OpenVR driver.
output - Controls what kind of category of data will be output from this node.
sensor- Output data such as sensor orientation and general information such as render resolution.
- Projection Matrices
projmatrices- Output the projection matrices for each eye.
controllers- Output controller state.
maxcontrollers - The maximum number of controller whose data should be output from this node.
firstcontroller - The first controller number to be output. For example if this is set to 2 and Max Controllers is 2, then data for controllers 2 and 3 will be output.
maxbuttons - The maximum number of buttons whose channels should be output for each controller.
maxanalogs - The maximum number of analog inputs (sliders, trackpads, joysticks) whose channels should be output for each controller.
orientation - When doing 'Sensor' output, controls of the orientation channels will be output. By default the units for orientation are 1 unit = 1 meter.
generalinfo - When doing 'Sensor' output, controls of general information channels will be output, such as render resolution and play area size.
near - When outputting 'Projection Matrices', controls the near plane the projection matrix will be built with.
far - When outputting 'Projection Matrices', controls the far plane the projection matrix will be built with.
unitscale - OpenVR by default works in a scale where 1 unit = 1 meter. This parameter allows the scale to be changed incase a scene is imported with a different scale.
