As good ole Captain Jack Sparrow returns for his 4th adventure, Cinesite was involved in creating the old classic London and other environments.  Using shots from the Old Royal Naval College in Greenwich, they used a special proprietary tool called ‘CsPhotoMesh’ to help in geometric reconstruction of the scene.  FXGuide has all the details.

“Given a set of digital images of a static scene, CsPhotoMesh produces a textured 3D mesh accurately representing the scene geometry and 3D cameras matching the original photos positions,” explains Stanley-Clamp. “The tool is fully automatic. All it requires is to drop all the images in a directory and run the command. This kicks off a reconstruction process on our renderfarm resulting in a 3D mesh and camera positions ready for texturing.”
