GestureMomentum

Struct GestureMomentum 

Source
pub struct GestureMomentum {
    pub pan: PanMomentum,
    pub zoom: AnchoredMomentum,
    pub bearing: AnchoredMomentum,
    pub pitch: AnchoredMomentum,
}
Expand description

How a gesture keeps moving the camera after the user lets go.

A part moves only when its velocity is set, and each part slows on its own. Every part defaults to MomentumDecayModel::Friction with a half-life of 140 ms, and these other defaults:

  • Pan stops at 10 logical pixels per second, needs a release of at least 200, and counts a release faster than 10000 as 10000.
  • Zoom stops at 0.01 levels per second and moves at most 2.5 levels. Its snap settles on the nearest whole level.
  • Bearing stops at 1 degree per second and needs a release of at least 60. Its snap settles on north within 7 degrees.
  • Pitch stops at 1 degree per second and needs a release of at least 5. Its snap settles flat within 7 degrees.

See mln_gesture_momentum in the C API reference.
