Abstract: Described herein is a foamable powder-based composition, comprising: (a) at least one powder-based polymer in an amount of no less than 8% by weight, based on the total weight of the composition, (b) at least one plurality of expandable microspheres in an amount of no less than 15% by weight, based on the total weight of the composition, and (c) optionally at least one filler, wherein the plurality of expandable microspheres in the composition expands when heating; and wherein the composition has a water content of no more than 3% by weight based on the total weight of the composition.

Abstract: Systems and techniques for selective transport of spatially partitioned immersive media content are described herein. In an example, the system may negotiate an attribute for media content between a media producer and a media consumer. A content structure for the media content may be determined based on the negotiation of the attribute, and a network packet may be created with information corresponding to the determined content structure encoded into a transport protocol header of the network packet. The network packet may be filtered to produce filtered media content. The filtered media content may be transmitted to the media consumer.
