evaluate()

void MayaFlux::Kinesis::CurveEvaluator::evaluate	(	const Eigen::MatrixXd &	control_points,
		Eigen::Index	num_samples,
		Eigen::MatrixXd &	out
	)

Evaluate a curve into a caller-owned matrix.

Parameters

control_points	MxN matrix, columns are control points.
num_samples	Output column count, at least 2.
out	Resized to rows(control_points) x num_samples and overwritten.

Boundary overload. Wraps evaluate_planar and transposes the result.
