|
|
// Generator with multiple modes: uniform, free, axis, fixed)
|
|
//
|
|
// Primary generator that can be configured using modes to either:
|
|
// - 'uniform' direction secondaries (default)
|
|
// - 'free' which is configured by UI - initialised in con/tor
|
|
// - 'axis' directing secondaries by rotation to x, y & z axis
|
|
// - 'fixed' along x axis, and near it ( y = 0.1 or z = 0.1)
