In one aspect, a conversation status of each of a plurality of communication channels is determined. Channels belonging to a first group status are grouped into a first set, and channels belonging to a second group status are grouped into a second set. Display data is generated to indicate the respective groupings, and audio and text is selectively displayed on user devices according to the groupings.

Abstract: Systems and methods for automatically animating a character based on an existing corpus of animation are described. The character may be from a previously produced feature animated film, and the data used for training may be the data used to animate the character in the film. A low-dimensional embedding for subsets of the existing animation corresponding to different semantic labels may be learned by mapping high-dimensional rig control parameters to a latent space. A particle model may be used to move within the latent space, thereby generating novel animations corresponding to the space's semantic label, such as a pose. Bridges may link a first pose of a first model within the latent space that is similar to a second pose of a second model of the space. Animations corresponding to transitions between semantic labels may be generated by creating animation paths that traverse a bridge from one model into another.

Abstract: Systems, methods, and computer-readable medium for approximating mesh deformations for character rigs are disclosed. An embodiment includes applying a first deformation function to one or more mesh elements to determine an intermediate position based on a transform to a first structural element, wherein the one or more mesh elements are assigned to the first structural element, generating an offset based on a second deformation function for the one or more mesh elements using a deformation function approximation model, wherein the offset is a positional offset of the one or more mesh elements from the intermediate position to a target position corresponding to the transform applied to the first structural element, and generating a combined mesh deformation for the one or more mesh elements by combining the intermediate position and the offset.

Abstract: A process for transitioning a reactor from base-catalyzed polyol production to double metal cyanide (DMC)-catalyzed polyol production is described. The process includes discharging a base-catalyzed and un-neutralized product mixture from a reactor, and adding an acidified polyether polyol starter and DMC catalyst mixture to the reactor. A DMC-catalyzed polyol production reaction can then be conducted in the reactor without intermediate washing or rinsing of the reactor, and without catalyst deactivation from base or alkaline hold-up.

Abstract: A lighting correction filter for selectively correcting lighting in computer animation is disclosed. The lighting correction filter can select a computer-generated object having one or more lighting attributes. The selected object can be a portion of an object, an entire object, a portion of a computer-generated scene, or an entire scene. The filter can then set lighting correction values for the lighting attributes of the selected object. The lighting correction values can be color values, exposure values, or both. The filter can apply the lighting correction values to the selected object's lighting attributes to effect a lighting correction in the object prior to rendering.
