Expand description

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<T: RealField, D: DimName>(
    mat: &OMatrix<T, D, D>
) -> bool where
    T::Epsilon: Copy,
    DefaultAllocator: Allocator<T, D, D>, [src]

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

Provided methods

fn has_normalizer() -> bool[src]

Indicates whether a Transform with the category Self has a bottom-row different from 0 0 .. 1.
