Video data of an environment may be prepared for presentation to a user in a virtual reality or augmented reality experience. According to one method, a plurality of locations distributed throughout a viewing volume may be designated, at which a plurality of vantages are to be positioned to facilitate viewing of the environment from proximate the locations. For each location, a plurality of images of the environment, captured from viewpoints proximate the location, may be retrieved. For each location, the images may be reprojected to a three-dimensional shape and combined to generate a combined image. The combined image may be applied to one or more surfaces of the three-dimensional shape to generate a vantage. The vantages may be stored such that the vantages can be used to generate viewpoint video of the scene, as viewed from a virtual viewpoint corresponding to an actual viewer's viewpoint within the viewing volume.
