  • Patent number: 10504282
    Abstract: Techniques for generating maps without shadows are discussed herein. A plurality of images can be captured by a vehicle traversing an environment representing various perspectives and/or lighting conditions in the environment. A shadow within an image can be identified by a machine learning algorithm trained to detect shadows in images and/or by projecting the image onto a three-dimensional (3D) map of the environment and identifying candidate shadow regions based on the geometry of the 3D map and the location of the light source. Shadows can be removed or minimized by utilizing blending or duplicating techniques. Color information and reflectance information can be added to the 3D map to generate a textured 3D map. A textured 3D map without shadows can be used to simulate the environment under different lighting conditions.

  • Patent number: 10424106
    Abstract: In some embodiments, a memory may store programming for selecting values describing a frame of pixels by modeling, based on camera data, object data, and material data, a geometric projection of light in a visual simulation, the modeling including identifying voxel data and building a voxel tree from the voxel data. A processor may, responsive to executing the programming, invoke one or more of a clipping module to generate a portion of the voxel data, a depth occlusion module to check for spatial visibility of one or more outputs of the clipping module and generate an output including one or more layers of a voxel tree, a re-projection module to conditionally generate a re-projection layer of the voxel tree, and an aggregation module to aggregate data of a final layer of the voxel tree with preceding layers to select an individual one of the values. Other embodiments may be disclosed and/or claimed.

  • Patent number: 10417813
    Abstract: A method for generating temporally stable hash values reduces visual artifacts associated with stochastic sampling of data for graphics applications. A given hash value can be generated from a scaled and discretized object-space for a geometric object within a scene. Through appropriate scaling, the hash value can be discretized and remain constant within a threshold distance from a pixel center. As the geometric object moves within the scene, a hash value associated with a given feature of the geometric object remains constant because the hash value is generated using an object-space coordinate anchored to the feature. In one embodiment, alpha testing threshold values are assigned random, but temporally stable hash output values generated using object-space coordinate positions for primitive fragments undergoing alpha testing. Alpha tested fragments are temporally stable, beneficially improving image quality.

  • Patent number: 10380712
    Abstract: A graphics processing system comprises a memory that stores graphics data. The graphics data stored in the memory is accessible using virtual memory addresses that map to physical memory addresses in the memory. The graphics processing system further comprises page merging circuitry configured to use metadata provided for a set of graphics data to determine whether any pages of the set of graphics data are similar to each other. The pages of the set of graphics data that are determined as being similar to each other are merged by mapping the virtual memory addresses for those pages to the same physical memory address in the memory. The page merging process can provide a way to reduce the number of physical memory addresses needed to store the pages of the set of graphics data in the memory.

  • Patent number: 10319134
    Abstract: According to one implementation, an animation system includes a computing platform having a hardware processor and a system memory storing a software code. The hardware processor executes the software code to receive pose data including rig control values for multiple animation rigs, and to store the rig control values for each animation rig in respective rig control caches identified with the animation rig. The hardware processor also executes the software code to receive constraint data linking one animation rig to one rig control cache identified with any animation rig, receive change data for one rig control value of that linked animation rig, update the rig control value based on the change data, and clear the rig control cache linked with the updated animation rig. Thus, updating any rig control value of an animation rig results in clearing rig control caches linked with that animation rig.
