  Abstract

Summary:

Traditional two-dimensional software programs for drawing pedigrees are limited when dealing with extended pedigrees. In successive generations, the number of individuals grows exponentially, leading to an unworkable amount of space required in the horizontal direction for 2D displays. In additionA large number of individuals cannot be clearly displayed in a given space, due to the exponential expansion of generations. When displaying large families, , it is not always possible to place closely related individuals near each other due to the lack of space in two dimensions. To address these issues we have developed three-dimensional pedigree drawing techniques to enable clearer visualisation of extended pedigrees. Currently no other methods are available for displaying extended pedigrees in three dimensions. We have made freely available a software tool – "Celestial3D" – that implements these novel techniques.
