Matt Pharr, Wenzel Jakob et Greg Humphreys avaient publié il y a 14 ans l’ouvrage Physically Based Rendering: From Theory to Implementation. Au fil des années, ce livre sur le rendu physique a été plusieurs fois mis à jour et réédité ; il était devenu une référence. Il avait même reçu un Academy Award for Scientific and Technical Achievement, lors de la cérémonie des Oscars Scientifiques et Techniques.
Il reste toutefois très onéreux : environ 70€ sur Amazon.fr, par exemple, et une cinquantaine d’euros en numérique.
Les auteurs viennent cependant d’annoncer la mise en ligne intégrale et gratuite de l’ensemble de l’ouvrage, que nous ne pouvons que vous inviter à consulter. Mieux encore : l’équipe explique que son projet est de proposer chaque année une version mise à jour du livre, pour tenir compte des dernières avancées techniques. Pour y parvenir, elle a mis en place un Patreon qui financera l’initiative.
Vous retrouverez ci-dessous le plan complet du livre. Le site officiel propose une version interactive, avec des liens permettant d’accéder directement aux différents chapitres.
