Struct trackball::Scene [−][src]
Scene wrt enclosing viewing frustum.
Implements Default
and can be created with Scene::default()
.
Implementations
impl<N: RealField> Scene<N>
[src]
pub fn fov(&self) -> Fixed<N>
[src]
Fixed quantity wrt field of view, see Self::set_fov()
.
pub fn set_fov(&mut self, fov: impl Into<Fixed<N>>)
[src]
Sets fixed quantity wrt field of view.
Default is fixed vertical field of view of π/4.
use nalgebra::Point2; use trackball::Scene; // Default screen size. let max = Point2::new(800, 600); // Default scene with fixed vertical field of view of π/4: // // * Increasing width increases horizontal field of view (more can be seen). // * Increasing height scales scene zooming in as vertical field of view is fixed. let mut scene = Scene::default(); // Unfix vertical field of view by fixing current unit per pixel on focus plane at distance // from eye of one, that is effectively `upp` divided by `zat` to make it scale-independant: // // * Increasing width increases horizontal field of view (more can be seen). // * Increasing height increases vertical field of view (more can be seen). scene.set_fov(scene.fov().to_upp(&max.cast::<f32>()));
pub fn clip_planes(&self, zat: N) -> (N, N)
[src]
Clip plane distances from eye regardless of Self::scale()
wrt to distance between eye
and target.
Default is (1e-1, 1e+6)
measured from eye.
pub fn set_clip_planes(&mut self, znear: N, zfar: N)
[src]
Sets clip plane distances from target or eye whether Self::scale()
.
Default is (1e-1, 1e+6)
measured from eye.
pub fn scale(&self) -> bool
[src]
Object inspection mode.
Scales clip plane distances by measuring from target instead of eye. Default is false
.
pub fn set_scale(&mut self, oim: bool)
[src]
Sets object inspection mode.
Scales clip plane distances by measuring from target instead of eye. Default is false
.
pub fn ortho(&self) -> bool
[src]
Orthographic projection mode.
Computes scale-identical orthographic instead of perspective projection. Default is false
.
pub fn set_ortho(&mut self, opm: bool)
[src]
Sets orthographic projection mode.
Computes scale-identical orthographic instead of perspective projection. Default is false
.
pub fn projection_and_upp(&self, zat: N, max: &Point2<N>) -> (Matrix4<N>, N)
[src]
Projection transformation and unit per pixel on focus plane wrt distance between eye and target and maximum position in screen space.
