Abstract: A rendering process and system that may be used to composite virtual objects in panoramic video to provide a virtual reality and augmented reality experience. The process includes receiving low dynamic range (LDR) video data, e.g. 360° video; generating radiance maps, such as diffuse and specular maps, from the LDR data; inverse tone mapping the LDR data of the maps to generate high dynamic range (HDR) data for the maps; and receiving at least one virtual object and applying image based lighting (IBL) to the virtual object using the HDR data of the maps. A perceptually based threshold is also applied to radiance maps to detect prominent pixels, and using the prominent pixels as salient lights for image based shadowing (IBS) associated the virtual object. Objects are composited 360° video in real time using IBL and IBS without precomputation allowing user interaction with the objects.

Abstract: A filter assembly is provided for removing entrained material from a fluid stream. The assembly includes a manifold with a port through which the fluid is received into or removed from the assembly, and a housing into which is inserted a tubular filter element having walls of a filtration medium. The housing and the manifold have joining formations which allow them to be joined together and separated apart by relative rotation. The filter element has an end cap thereon which sealingly engages with the manifold. The end cap has an opening therein which accepts fluid received through the port and feeds the fluid into the interior of the filter element or which accepts fluid received from the interior of the filter element and feeds the fluid to the port. The filter element is insertable into the housing along the axial direction of the filter element.
