The range of movement is displayed on-screen to the artist, together with the computer-generated character. In this way, the rail manipulator directly communicates to the artist the degree to which a portion of the computer-generated character can be moved, in response to the artist's selection of the portion of the computer-generated character.

Stereoscopic modeling based on maximum ocular divergence of a viewer
A computer-implemented method for computing an effective inter-ocular distance for a modeled viewer based on a maximum ocular divergence angle. A maximum ocular divergence angle, viewing distance, and an inter-ocular distance are obtained for the modeled viewer.

A minimum scene depth is calculated based on the distance from the pair of cameras to a nearest point of interest in the computer-generated scene. A near-parallax value is also calculated based on the focal length and the minimum scene depth. Calculating the near-parallax value includes selecting a baseline stereo-setting entry from a set of stereo-setting entries, each stereo-setting entry of the set of baseline stereo-setting entries includes a recommended scene depth, a recommended focal length, and a recommended near-parallax value. For the selected baseline stereo-setting entry: the recommended scene depth corresponds to the minimum scene depth, and the recommended focal length corresponds to the focal length. The near-parallax value and far-parallax value are stored as the bounded-parallax constraints for the placement of the pair of stereoscopic cameras.

Systems and processes are described below relating to evaluating a dependency graph having one or more temporally dependent variables. The temporally dependent variables may include variables that may be used to evaluate the dependency graph at a frame other than that at which the temporally dependent variable was evaluated. One example process may include tracking the temporal dirty state for each temporally dependent variable using a temporal dependency list. This list may be used to determine which frames, if any, should be reevaluated when a request to evaluate a dependency graph for a particular frame is received. This advantageously reduces the amount of time and computing resources needed to reevaluate a dependency graph.

An animated special effect is modeled using a fluid dynamics framework system. The fluid dynamics framework for animated special effects system accepts volumetric data as input. Input volumetric data may represent the initial state of an animated special effect. Input volumetric data may also represent sources, sinks, external forces, and/or other influences on the animated special effect. In addition, the system accepts input parameters related to fluid dynamics modeling. The input volumes and parameters are applied to the incompressible Navier-Stokes equations as modifications to the initial state of the animated special effect, as modifications to the forcing term of a pressure equation, or in the computations of other types of forces that influence the solution. The input volumetric data may be composited with other volumetric data using a scalar blending field. The solution of the incompressible Navier-Stokes equations models the motion of the animated special effect.

A high dynamic range (HDR) image can be lossy compressed by first mapping floating point image data values of the HDR image from a light linear space to a perceptually linear space using a first non-linear mapping function. A value in the light linear space is proportionate to the power of a light source, and a value in the perceptually linear space is proportionate to a visual perceived brightness. Floating point discrete cosine transform (DCT) frequency coefficients of the floating point image data values of the HDR image are determined. The floating point DCT frequency coefficients are quantized. The quantized floating point DCT frequency coefficients are compressed. The compression of the quantized floating point DCT frequency coefficients is lossless. The compressed quantized floating point DCT frequency coefficients are stored.
