US Patent:

61150517, Sep 5, 2000

Filed:

Aug 7, 1996

Appl. No.:

8/693942

Inventors:

David P. Simons - Lynnfield MA
Scott S. Snibbe - Seatle WA

Assignee:

Adobe Systems Incorporated - San Jose CA

International Classification:

G06T 1100

US Classification:

345442

Abstract:

A computer-implemented method and apparatus for reparameterizing a parametric function representing an animation feature in an animation system where the parametric function is represented by a curve having unequal arc-length per unit parameter. The system samples at intervals of the parameter along the length of the curve and then calculates the arc-length over each interval. Thereafter, one or more differentiable curves are fitted to the parameter, arc-length pairs.

Abstract:

A method for compositing first and second digital images having different pixel aspect ratios to reduce distortion of image content. The method includes determining a scaling factor from first and second pixel aspect ratios; scaling a first image by the scaling factor; and compositing the first and second images into a composite image. The scaling step may be limited to stretching or squashing the first image in only a horizontal direction. The scaling step may include resampling the first image. In another aspect, the invention features a method for controlling motion along a motion path in a composition having nonsquare pixels. The method includes determining a scaling factor based on the composition pixel aspect ratio; applying the scaling factor to a copy of the motion path; reparameterizing the copy of the motion path to generate a scaled motion mapping; and using the scaled motion mapping to control motion along the motion path. The motion path may define the motion of a layer in the composition.

Abstract:

A manifold for distributing a circulating fluid, such as water, to multiple zones of a hydronic system, such as a hot water heating system. The manifold is of unitary construction and includes a plurality of distribution branches and an air scoop extending from a common header conduit. The air scoop extracts air from the water being circulated through the manifold. The air scoop may be coupled to an air vent to purge air from the water. The manifold may also include an expansion tank coupling that is disposed on the header conduit to couple the tank to the header conduit. The air scoop may include a housing affixed to the header conduit and a baffle that protrudes into the header conduit to direct air into the housing so that it can be vented through the air vent. The baffle may be angled relative to the longitudinal axis of the header conduit.
