Function spirv_std::arch::ddy_fine_vector [−][src]
pub fn ddy_fine_vector<F: Float, VECTOR: Vector<F, LENGTH>, const LENGTH: usize>(
component: VECTOR
) -> VECTOR
Returns the partial derivative of Self
with respect to the window’s
Y coordinate. Uses local differencing based on the value of Self
for
the current fragment and its immediate neighbor(s).
