Far Beam

The far beam component allows the user to visualise elements in the scene they can interact with from afar.

If you wish to customise the look of the beam, you can set the beam material by calling SetBeamMaterial with the material you wish to use. This material can have the following parameters if you wish to use them in your material.

• IsGrabbing: Scalar parameter. This value will be 0.0f if the user is not grabbing with the far cursor, 1.0f if they are.
• handIndex: Scalar parameter. This value will be 0.0f for the left hand, 1.0f for the right hand.

The default material for the far beam has the following parameters:
