We use the reverse search technique to give algorithms for generating all graphs onn points that are 2- and 3-connected planar triangulations withr points on the outer face. The triangulations are rooted, which means the outer face has a fixed labelling. The triangulations are produced without duplications inO(n2) time per triangulation. The algorithms useO(n) space. A program for generating all 3-connected rooted triangulations based on this algorithm is available by ftp.
