## Implementations§

source§### impl<T> Perspective3<T>

### impl<T> Perspective3<T>

source#### pub const fn from_matrix_unchecked(matrix: Matrix4<T>) -> Self

source#### pub fn into_inner(self) -> Matrix4<T>

#### pub fn into_inner(self) -> Matrix4<T>

Retrieves the underlying homogeneous matrix.

source#### pub 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.

source#### pub fn project_point(&self, p: &Point3<T>) -> Point3<T>
