摘要： An image dataset comprising pixel depth arrays might be processed by an interpolator, wherein interpolation is based on pixel samples. Input pixels to be interpolated from and an interpolated pixel might comprise deep pixels, each represented with a list of samples. Accumulation curves might be generated from each input pixel, weights applied, and accumulation curves combined to form an interpolation accumulation curve. An interpolated deep pixel can be derived from the interpolation accumulation curve, taking into account zero-depth samples as needed. Samples might represent color values of pixels.

摘要： A method of optimizing a pose of a character is disclosed. An input is received. The input defines one or more effectors. A pose is generated for the character using a learned inverse kinematics (LIK) machine-learning (ML) component. The LIK ML component is trained using a motion dataset. The generating of the pose is based on one or more criteria. The one or more criteria include explicit intent expressed as the one or more effectors. The generated pose is adjusted using an ordinary inverse kinematics (OIK) component. The OIK component solves an output from the LIK ML component to increase an accuracy at which the explicit intent is reached. A final pose is generated from the adjusted pose. The generating of the final pose includes applying a physics engine (PE) to an output from the OIK component to increase a physics accuracy of the pose.

摘要： A realistic feather generation may be represented via a user interface in a modeling system. To perform the feather generation, a curve defining a spine of a feather is received from input to the user interface of the modeling system. The feather is created in the user interface based at least on the curve, where the feather includes barbs extended away from the spine of the feather in one or more directions. The feather is deformed based on one or more deformation parameters. A feather contour of the barbs along at least one of the one or more directions is generated based on a contour parameter defining the feather contour. A barb density for a number of the barbs along the spine of the feather is established based on a barb density parameter. Thereafter, a data structure representing the feather is generated.

摘要： A combustion simulation system is provided. The combustion simulation system can be performed using a computing device operated by a computer user or artist. The computer-implemented method of generating one or more visual representations of a combustion even is provided. The method includes simulating the combustion event, which transforms combustion reactants into combustion products, the combustion event occurring at a reference pressure, automatically determining values of combustion properties, the values of the combustion properties being calculated as a function of a nonzero pressure field, and generating the one or more visual representations of the combustion event based on the values of combustion properties.

摘要： In an image processing system, an image insertion is to be included onto, or relative to, a first and second frame, each depicting images of a set of objects of a geometric model. A point association is determined for a depicted object that is depicted in both the first frame and the second frame, representing reference coordinates in a virtual scene space of a first location on the depicted object independent of at least one position change and a mapping of a first image location in the first image to where the first location appears in the first image. A corresponding location in the second image is determined based on where the first location on the depicted object appears according to the reference coordinate in the virtual scene space and a second image location on the second image where the first location appears in the second image.

摘要： An animation system is provided for generating an animation control rig for character development, configured to manipulate a skeleton of an animated character. Hierarchical representation of puppets includes groups of functions related in a hierarchy according to character specialization for creating the animated rig are derived using base functions of a core component node. The hierarchical nodes may include an archetype node, at least one appendage node, and at least one feature node. In some implementations, portions of a hierarchical node, including the functions from the core component node, may be shared to generate different animation rigs for a variety of characters. In some implementations, portions of a hierarchical node, including the component node functions, may be reused to build similar appendages of a same animation rig.

摘要： An active marker relay system is provided to operate responsive active markers coupled to an object in a live action scene for performance capture, via a trigger unit that relays energy pulse information to responsive active markers. Using use simple sensors, the responsive active markers sense control energy pulses projected from the trigger unit. In return, the responsive active markers produce energy pulses that emulate at least one characteristic of the control energy pulses, such as a particular pulse rate or wavelength of energy. The reactivity of the responsive active markers to control energy pulses enables simple control of the responsive active markers through the trigger unit.

摘要： An image generation system defines a set of deformation handles having an associated set of one or more control parameters, obtains a set of object points representative of a virtual object, maps the set of object points to a plurality of key pose states, wherein the key pose state is represented by a key pose state data structure corresponding to a key pose that specifies control parameters to place the set of the deformation handles to coincide with the set of object points, determines corresponding key pose state data structures, receives a set of deformations to be applied to the set of deformation handles, interpolates poses among an interpolated key pose state set to form a current pose state based on the set of deformations, and adjusts the virtual object based on the interpolated key pose state set.

摘要： A realistic feather growth may be represented between two surface manifolds in a modeling system. To perform the feather growth, a feather groom for a plurality of feathers between an inner shell of a creature and an outer shell of the creature is received. An inner manifold for the inner shell and an outer manifold for the outer shell is determined with a plurality of follicle points and a plurality of tip points. A first surface contour definition for the inner manifold and a second surface contour definition for the outer manifold is determined and used to determine a volumetric vector field between the inner manifold and the outer manifold. Thereafter, the plurality of feathers is generated between the inner manifold and the outer manifold using the follicle points, the tip points, and the volumetric vector fields.

摘要： Methods and systems are presented for generating a rendering of a virtual scene of a plurality of virtual scene elements. Rendering can take into account a camera position of a camera in a stage environment that is to be used to capture a captured scene, a display position of a virtual scene display in the stage environment, a set of depth slices, wherein a depth slice of the set of depth slices represents a subregion of the virtual scene space, and a blur factor for the depth slice based at least in part on the camera position, the display position, and a depth value or depth range for the subregion of the virtual scene space represented by the depth slice. Using depth slices can reduce computational efforts.
