extract_value()

double MayaFlux::Nodes::Input::InputNode::extract_value ( const Core::InputValue &  value )

protectedvirtual

Extract a scalar value from an InputValue.

Parameters

value

The input value to extract from

Returns

Scalar value for smoothing/output

Override in derived classes for specific input types. Default handles SCALAR and MIDI CC values.

Reimplemented in MayaFlux::Nodes::Input::HIDNode, and MayaFlux::Nodes::Input::MIDINode.
