impl<T> Perspective3<T>
sourcepub const fn from_matrix_unchecked(matrix: Matrix4<T>) -> Self
pub const fn from_matrix_unchecked(matrix: Matrix4<T>) -> Self

.
sourcepub fn into_inner(self) -> Matrix4<T>
pub fn into_inner(self) -> Matrix4<T>
Retrieves the underlying homogeneous matrix.
sourcepub fn unwrap(self) -> Matrix4<T>
👎Deprecated: use .into_inner()
instead
pub fn unwrap(self) -> Matrix4<T>
.into_inner()
insteadRetrieves the underlying homogeneous matrix.
Deprecated: Use Perspective3::into_inner
instead.
sourcepub fn project_point(&self, p: &Point3<T>) -> Point3<T>

Updates this perspective matrix with a new width / height
aspect ratio of the view
frustum.

sourcepub fn set_zfar(&mut self, zfar: T)
pub fn set_zfar(&mut self, zfar: T)
Updates this perspective matrix with a new far plane offset of the view frustum.
sourcepub fn set_znear_and_zfar(&mut self, znear: T, zfar: T)
pub fn set_znear_and_zfar(&mut self, znear: T, zfar: T)
Updates this perspective matrix with new near and far plane offsets of the view frustum.
