A user interface to a virtual camera for a 3-D rendering application provides various features. A rendering engine can continuously refine the image being displayed through the virtual camera, and the user interface can contain an element for indicating capture of the image as currently displayed, which causes saving of the currently displayed image. Autofocus (AF) and autoexposure (AE) reticles can allow selection of objects in a 3-D scene, from which an image will be rendered, for each of AE and AF. A focal distance can be determined by identifying a 3-D object visible at a pixel overlapped by the AF reticle, and a current viewpoint. The AF reticle can be hidden in response to a depth of field selector being set to infinite depth of field. The AF and AE reticles can be linked and unlinked, allowing different 3-D objects for each of AF and AE.

Virtual camera for 3-D modeling applications

Systems and methods for producing an acceleration structure provide for subdividing a 3-D scene into a plurality of volumetric portions, which have different sizes, each being addressable using a multipart address indicating a location and a relative size of each volumetric portion. A stream of primitives is processed by characterizing each according to one or more criteria, selecting a relative size of volumetric portions for use in bounding the primitive, and finding a set of volumetric portions of that relative size which bound the primitive. A primitive ID is stored in each location of a cache associated with each volumetric portion of the set of volumetric portions. A cache location is selected for eviction, responsive to each cache eviction decision made during the processing. An element of an acceleration structure according to the contents of the evicted cache location is generated, responsive to the evicted cache location.

Systems and methods for 3-D scene acceleration structure creation and updating

Methods, systems, devices and computer software/program code products enable generating reduced-noise image frames based on image frames received from a digital camera pipeline; and enable efficient stereo image search between corresponding images generated by at least two cameras.

Temporal de-noising

In some aspects, systems and methods provide for forming groupings of a plurality of independently-specified computation workloads, such as graphics processing workloads, and in a specific example, ray tracing workloads. The workloads include a scheduling key, which is one basis on which the groupings can be formed. Workloads grouped together can all execute from the same source of instructions, on one or more different private data elements. Such workloads can recursively instantiate other workloads that reference the same private data elements. In some examples, the scheduling key can be used to identify a data element to be used by all the workloads of a grouping. Memory conflicts to private data elements are handled through scheduling of non-conflicted workloads or specific instructions and/or deferring conflicted workloads instead of locking memory locations.

Graphics processor with non-blocking concurrent architecture

Ray tracing, and more generally, graphics operations taking place in a 3-D scene, involve a plurality of constituent graphics operations. Responsibility for executing these operations can be distributed among different sets of computation units. The sets of computation units each can execute a set of instructions on a parallelized set of input data elements and produce results. These results can be that the data elements can be categorized into different subsets, where each subset requires different processing as a next step. The data elements of these different subsets can be coalesced so that they are contiguous in a results set. The results set can be used to schedule additional computation, and if there are empty locations of a scheduling vector (after accounting for the members of a given subset), then those empty locations can be filled with other data elements that require the same further processing as that subset.

Methods, systems, devices and computer software/program code products enable reconstruction of synthetic images of a scene from the perspective of a virtual camera having a selected virtual camera position, based on images of the scene captured by a number of actual, physical cameras.

Image reconstruction for virtual 3D
