Trait nalgebra::geometry::TCategory

pub trait TCategory: Any + Debug + Copy + PartialEq + Send {
    fn check_homogeneous_invariants<N: RealField, D: DimName>(
        mat: &MatrixN<N, D>
    ) -> bool
    where
        N::Epsilon: Copy,
        DefaultAllocator: Allocator<N, D, D>;

    fn has_normalizer() -> bool { ... }
}

Trait implemented by phantom types identifying the projective transformation type.

NOTE: this trait is not intended to be implemented outside of the nalgebra crate.

Required methods

fn check_homogeneous_invariants<N: RealField, D: DimName>(

) -> bool where
    N::Epsilon: Copy,
    DefaultAllocator: Allocator<N, D, D>, 

Checks that the given matrix is a valid homogeneous representation of an element of the category Self.
