Struct Slide

Source 
pub struct Slide<N: Copy + RealField> { /* private fields */ }
Expand description

Slide induced by displacement on screen.

Implements Default and can be created with Slide::default().

Both its methods must be invoked on matching events fired by your 3D graphics library of choice.

Implementations§

Source§

impl<N: Copy + RealField> Slide<N>

Source

pub fn compute(&mut self, pos: Point2<N>) -> Option<Vector2<N>>

Computes slide between previous and current cursor/finger position in screen space.

Source

pub fn discard(&mut self)

Discards cached previous cursor/finger position on button/finger release.

Source

pub fn cast<M: Copy + RealField>(self) -> Slide<M>
where N: SubsetOf<M>,

Casts components to another type, e.g., between f32 and f64.
