Struct trackball::First [−][src]
pub struct First<N: RealField> { /* fields omitted */ }
First person view induced by displacement on screen.
Implements Default
and can be created with First::default()
.
All methods except Self::enabled()
must be invoked on matching events fired by your 3D
graphics library of choice.

[src]pub fn capture(&mut self, yaw_axis: Unit<Vector3<N>>)
[src]
pub fn capture(&mut self, yaw_axis: Unit<Vector3<N>>)
[src]Captures current yaw axis when entering first person view.
pub fn compute(
&mut self,
vec: &Vector2<N>,
max: &Point2<N>
) -> Option<(N, N, &Unit<Vector3<N>>)>
[src]
pub fn compute(
&mut self,
vec: &Vector2<N>,
max: &Point2<N>
) -> Option<(N, N, &Unit<Vector3<N>>)>
[src]Computes pitch and yaw from cursor/finger displacement vector in screen space.
Carries cursor/finger displacements to arcs of the same length on great circles of an
eye-centered trackball with radius of maximum of half the screen’s width and height in
compliance with crate::Orbit
except that its trackball is target-centered.

Checks if self
is actually part of its subset T
(and can be converted to it).

Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
