The hidden secrets of flowers

The hidden secrets of flowers To better understand the evolution of flowers, researchers from Montreal are harnessing photogrammetry - a technique commonly used by geographers to reconstruct landscape topography. This is the first time scientists have used the technique to study flowers. The team, including researchers from McGill University, Université de Montréal, and the Montreal Botanical Garden, published the results of their work in the journal New Phytologist . Photogrammetry uses information gathered from photos taken from different angles. Thanks to the triangulation of common points present on the photos, it's possible to reconstruct a 3D model of a flower. Colours are then applied to the 3D flower using information from the photos.
