[src]
This transformation seen as a Projective3
.
pub fn into_inner(
self
) -> Matrix<N, U4, U4, <DefaultAllocator as Allocator<N, U4, U4>>::Buffer>
[src]
self
) -> Matrix<N, U4, U4, <DefaultAllocator as Allocator<N, U4, U4>>::Buffer>
Retrieves the underlying homogeneous matrix.
pub fn unwrap(
self
) -> Matrix<N, U4, U4, <DefaultAllocator as Allocator<N, U4, U4>>::Buffer>
[src]
self
) -> Matrix<N, U4, U4, <DefaultAllocator as Allocator<N, U4, U4>>::Buffer>
use .into_inner()
instead
Retrieves the underlying homogeneous matrix. Deprecated: Use Perspective3::into_inner instead.
pub fn aspect(&self) -> N
[src]
Gets the width / height
aspect ratio of the view frustum.
pub fn fovy(&self) -> N
[src]
Gets the y field of view of the view frustum.
pub fn znear(&self) -> N
[src]
Gets the near plane offset of the view frustum.
pub fn zfar(&self) -> N
[src]
Gets the far plane offset of the view frustum.
pub fn project_point(&self, p: &Point<N, U3>) -> Point<N, U3>
[src]
Projects a point. Faster than matrix multiplication.
pub fn unproject_point(&self, p: &Point<N, U3>) -> Point<N, U3>
[src]
Un-projects a point. Faster than multiplication by the matrix inverse.
