The present disclosure relates to systems, non-transitory computer-readable media, and methods for intelligently blending inverse kinematic (IK) solutions to more naturally depict joint positioning and/or movement of digital animated characters. In particular, in one or more embodiments, the character animation system can blend two IK solutions for an elbow joint based on a shoulder angle. For example, the character animation system can utilize a blending region to dynamically blend IK solutions as the shoulder angle moves through the blending region, thereby smoothly modifying bend direction and elbow position of the animated character arm. Based on the modified elbow position relative to a wrist position and a shoulder position, the animated character system can simulate more accurate, natural arm movements while reducing time and interactions needed to generate realistic animation sequences.

Systems and methods for switching to different states of electronic content being developed in a content creation application. This involves storing different states of the electronic content using a content-addressable data store, where individual states are represented by identifiers that identify items of respective states stored in the content-addressable data store. Identical items that are included in multiple states are stored once in the content-addressable data store and referenced by common identifiers. Input is received to change the electronic content to a selected state of the different states and the electronic content is displayed in the selected state based on identifiers for the selected state. In this way, undo, redo, and other commands to switch to different states of electronic content being developed are provided.

One exemplary embodiment involves receiving a plurality of three-dimensional (3D) track points for a plurality of frames of a video, wherein the 3D track points are extracted from a plurality of two-dimensional source points. The embodiment further involves rendering the 3D track points across a plurality of frames of the video on a two-dimensional (2D) display. Additionally, the embodiment involves coloring each of the 3D track points wherein the color of each 3D track point visually distinguishes the 3D track point from a plurality of surrounding 3D track points, and wherein the color of each 3D track point is consistent across the frames of the video. The embodiment also involves sizing each of the 3D track points based on a distance between a camera that captured the video and a location of the 2D source points referenced by the respective one of the 3D track points.

One exemplary embodiment involves identifying a plane defined by a plurality of three-dimensional (3D) track points rendered on a two-dimensional (2D) display, wherein the 3D track points are rendered at a plurality of corresponding locations of a video frame. The embodiment also involves displaying a target marker at the plane defined by the 3D track points to allow for visualization of the plane, wherein the target marker is displayed at an angle that corresponds with an angle of the plane. Additionally, the embodiment involves inserting a 3D object at a location in the plane defined by the 3D track points to be embedded into the video frame. The location of the 3D object is based at least in part on the target marker.

Methods and apparatus disclosed herein receive a non-integer star points input parameter value, create a star shape with a number of star points equal to an integer portion of the star points input parameter plus one, and store or render the star shape to an output device. A fractional star point is differentiated from integer star points by a differential radial length between the two. Some embodiments also receive a non-integer polygon sides input parameter value and render a modified polygon shape with a total number of sides equal to an integer portion of the polygon sides input parameter plus one. A number of sides equal to the integer portion of the polygon sides parameter minus one are rendered as regular polygon sides. Two sides are rendered as adjacent symmetrical bezier curves, and the modified polygon shape is stored or rendered to an output device.

Techniques for representing a stroke in an image, the stroke being defined by a path extending across one or more positions in the image and one or more stroke parameters, each stroke parameter representing an appearance attribute of the stroke. The techniques include associating values for the one or more stroke parameters with time values in a time dimension of the stroke, the parameter values being associated with the time values independent of position along the stroke path; and representing the stroke according to the parameter values and their associated time values.

Methods and apparatus, including computer program products, for modifying the appearance of a text object. A modification hierarchy includes a plurality of modifiers, selection functions, and/or property operations. Each modifier includes one or more selection functions and one or more property operations. Each selection function defines a selection of at least a portion of one or more text units in a text object. Each property operation specifies an operation to be performed to modify one or more properties for text units in the selection. The modification hierarchy is defined by logical relationships between the modifiers, the selection functions and the property operations. The modification hierarchy is applied to the text object to modify the specified properties for the text units in the selection according to the selection functions and the property operations.

Methods and apparatus, including computer program products, implementing and using techniques for generating a composite image from both two-dimensional (2D) image layers and three-dimensional (3D) image layers. In one embodiment, the image layers are arranged in a sequence in which a top 3D image layer is separated from a bottom 3D image layer by a 2D image layer and the image layers are rendered according to the sequence. In another embodiment, at least one of the image layers is associated with an adjustment layer, and rendering the composite image includes determining whether each current image layer has an associated adjustment layer with a dimensionality different from that of the current image layer, and if it does, applying the adjustment layer accordingly. In another embodiment, at least one of the image layers is associated with a track matte.

Methods and apparatus, including computer program products, implementing and using techniques for generating a composite image. Electronic data representing image layers to be combined in a composite image is provided. At least one of the image layers has two-dimensional content. At least one of the image layers has three-dimensional content. The layers are arranged in a composition sequence list. The image layers are grouped into metalayers including image layers with content of a common dimensionality. The metalayers are arranged in a metalayer sequence. A metalayer is selected according to the metalayer sequence and the image layers in the selected metalayer are processed to generate a raster representation of the image layers in the selected metalayer. The raster representation is composited into an image buffer and the process is repeated until the raster representation of each of the metalayers have been composited into the image buffer to form a composite image.
